[Botany • 2020] Drosera buubugujin (Droseraceae, sect. Prolifera) • A spectacular New Species of Sundew from the Cape York Peninsula Bioregion, Australia

Drosera buubugujin M.T.Mathieson

in Mathieson et Thompson, 2020. 

Drosera buubugujin is described as new. It is a terrestrial herb known only from Muundhi and Juunju Daarrba Nhirrpan National Parks (Cape York Peninsula Aboriginal Land - CYPAL) in northern Queensland and is readily distinguished from any other members of the genus by its unique combination of characters. The species is illustrated and diagnosed herein. A key is provided to the species of Drosera section Prolifera. Its conservation status is assessed and a status of Critically Endangered is recommended. 

Key Words: Droseraceae; Drosera; Drosera buubugujin; Australia flora; Queensland flora; new species; taxonomy; identification key; conservation status 

 

Drosera buubugujin M.T.Mathieson sp. nov. with affinity to D. schizandra, but differing by the lateral inflorescence presentation, smaller flowers, shortly and thickly bilobed anther filaments, white to creamy white anthers and pollen, and predominantly oblanceolate to obovate leaf shape.

Etymology: This species is named after the Buubu Gujin Aboriginal Corporation lands, which include Muundhi and Juunju Daarrba Nhirrpan National Parks (CYPAL) where it was collected.

Abstract

Drosera maanyaa-gooljoo, a new annual species of Drosera section Arachnopus from the remote Buccaneer Archipelago and Yampi Peninsula in the northwest Kimberley region of Western Australia, is described and illustrated. Drosera maanyaa-gooljoo is a distinctive species that differs in morphology and indumentum from all previously known taxa of D. section Arachnopus. Comprehensive photo plates comparing all morphological details, as well as seed shape and structure, with those of the putatively related D. barrettiorum and D. hartmeyerorum are provided. Given D. maanyaa-gooljoo is only known from two small populations, a Priority One status under Conservation Codes for Western Australian Flora is recommended. Both populations occur within exclusive Native Title lands of the Dambimangari and Mayala Traditional Owners. This exciting new species discovery highlights the importance of both consultation with Indigenous people and herbarium revisions for alpha taxonomy and biodiversity research.

It is essential for scientists who conduct research on Country to recognise the knowledge, skills, and interest in land management of Aboriginal people. We consulted with both Traditional Owner groups of the area where this species occurs over multiple years, and it was eventually decided to name this species with an Aboriginal name. Naming new species with Aboriginal words selected by the Traditional Owners themselves is rapidly becoming a common praxis in taxonomic research, especially for narrowly endemic taxa that only occur in a small area managed by a single Traditional Owner group (see, e.g., the recently described Drosera buubugujin). As in our case there are two different Traditional Owner groups speaking two different languages, a compromise for the species name had to be found. Each group selected their own name for this species and both words were then combined with a hyphen. The word “maanyaa” means centipede in the Worrora language spoken by the Dambimangari, a clear reference to the curved, sickle-shaped lamina and the extremely long tentacles of this species. The Mayala selected the word “gooljoo” which means grass in the Bardi language. As both words stand independently in the specific epithet, the use of a hyphen is permitted in this case according to the rules of taxonomic nomenclature.

[Botany • 2020] Drosera stipularis (Droseraceae) • A New Species for the D. petiolaris Complex from Cape York Peninsula, Queensland, Australia

Abstract
Across tropical northern Australia 14 Drosera species are recognised within the D. petiolaris complex. The complex is placed in section Lasiocephala; a group of perennial sundews mostly characterised by an indumentum of white hairs upon the petiole. Here we describe a new species for the complex, D. stipularis Baleeiro, R.W.Jobson & R.L.Barrett, which is known only from white-sand habitats on Cape York Peninsula, Queensland. The new species is allied to D. petiolaris R.Br. ex DC. and D. lanata K.Kondo.



Drosera stipularis Baleeiro, R.W.Jobson & R.L.Barrett, sp. nov.

 Type: Queensland: Cape York Peninsula, [precise locality withheld] R.W. Jobson 3134 & P.C. Baleeiro, 13 Apr 2016 (holo: NSW 1056757; iso: BRI). 

Diagnosis: Drosera stipularis is similar to D. petiolaris and D. lanata but differs by its slender v. thickened stems with perennating buds held above v. at or below ground level, the petiole not elongating post anthesis v. elongating to 40 mm long, petiole distal end reflexed v. straight, inflorescences being mostly glabrous v. hairy below first flower, short pedicels up to 0.6 mm long v. 3.0 mm long at anthesis, and the prominent stipules exserted well above the central rosette v. stipules not being prominent.

Etymology: The specific epithet refers to the erect to spreading stipules exserted above the central rosette.

 Distribution and Ecology: Known only from two collections north of Cooktown and east of Starke National Park. Our examination of Drosera collections at BRI, and NSW, and examination of images of collections from the vicinity (held at CNS and JCU), uncovered no additional specimens. Both 2013 and 2016 specimens were located c. 300 m apart from each other. Found on moist pockets (each pocket c. 20 m2 ) of fine sand substrate within low heath and sedges (Fig. 3). The moist fine sand pockets were infrequent across the location and were not observed elsewhere in nearby habitat. Within each pocket D. stipularis was common, forming several scattered colonies each containing c. 30 individuals (P.C. Baleeiro pers. obs.). Found in flower in April and July.

 DOI:  10.11646/phytotaxa.501.1.2

Abstract

A new annual species of Drosera section Arachnopus, Drosera margaritacea, from the western Kimberley region (Western Australia) is described and illustrated, including detailed comparisons with the morphologically most similar species, D. finlaysoniana. The latter name is lectotypified here. The global range of D. finlaysoniana is provided, including a doubtful first record for Thailand, while the species, in contrast with statements made in some published references, does not occur in India, Laos, Cambodia and the Philippines. Additionally, the first record from Indonesia of the frequently misidentified D. aquatica is reported.

Drosera margaritacea T.Krueger & A.Fleischm., sp. nov. 

Diagnosis:—Drosera margaritacea is morphologically similar to Drosera finlaysoniana Wall. ex Arn. in Hook. from which it differs (contrasting characters in parentheses) by its petiolate leaves, borne on a 1.5–3.5 mm long petiole (leaves sessile), petiole covered with 20–50 stalked secretive glands 0.10–0.40 mm long with a multicellular stalk and translucent milky white, hemispherical to depressed ovoid gland head 0.10–0.30 mm in diameter that remains present even in dried material (petiole absent), stem, leaves, peduncle, pedicels and sepals covered with 0.05–0.30 mm long stalked capitate trichomes with uniseriate stalk and yellow, spherical, non-secretory gland head ca. 0.05 mm in diameter (stem, abaxial leaf surface, peduncle, pedicels and sepals covered with 0.1–0.3 mm long secretory capitate trichomes with uniseriate stalk and flattened gland head secreting a translucent mucilage droplet 0.1–0.2 mm in diameter), T-or Y-shaped trichomes absent (adaxial leaf bases and margins covered with 0.05–0.40 mm long T-or Y-shaped trichomes), inflorescence (20–)30–55(–65) cm long, with at least 30–50 flowers, its peduncle held upright, ± parallel to stem and much exceeding the carnivorous leaves (inflorescence (3–)6–18(–26) cm long, (2–)6–20(–26)- flowered, peduncle usually horizontal [this character is typically very obvious in live specimens, but sometimes not easily discerned in pressed herbarium material], shorter than or at most equalling the leaves in length), flowers 18–24 mm in diameter (7–14(–20) mm in diameter), stamen connective longer than filament, shorter than thecae and with rounded yellow tip ca. 0.2–0.4 mm in diameter (stamen connective usually much shorter than filament, as long as the thecae, lacking a rounded yellow tip).

Etymology:—The species’ epithet (from Latin margaritaceus = pearly, pearl-bearing) refers to the indumentum of unique, stalked secretive glands with translucent milky white, hemispherical to depressed ovoid (pearl-like) gland heads, as well as to the characteristic swollen, roundish (pearl-like) apical dilatation of the anther connective.

 DOI: 10.3372/wi.48.48106

Abstract

Drosera xerophila A. Fleischm., a new species of sundew from Overberg District, Western Cape Province, South Africa, is described and illustrated together with details on its distribution, ecology, habitats and conservation status. The new species is morphologically compared with presumably closely related taxa. An identification key and synopsis are provided for all rosetted hemicryptophyte (”perennially growing”) Drosera species of the SW part of Western Cape Province, with synonymy, types, distribution (including maps) and citation of specimens and georeferenced photographs. The names D. aliciae Raym.-Hamet, D. curviscapa T. M. Salter and D. curviscapa var. esterhuyseniae T. M. Salter are lectotypified.

Key words: carnivorous plants, Drosera, Droseraceae, Fernkloof Nature Reserve, fynbos, new species, nomenclature, Overberg District, South Africa, sundew, taxonomy, typification, Western Cape Province

Fleischmann.

Drosera xerophila A. Fleischm., sp. nov.

Diagnosis: — Related to Drosera esterhuyseniae (T. M. Salter) Debbert, but differs from that species in having broadly spatulate, decumbent, rosette leaves (leaves narrowly cuneate to rectangular, held upright at an angle of 70°–30°) and glabrous, emarginate to bifid stigmatic tips (stigmas entire, knob-shaped, papillate). Resembles D. aliciae Raym.-Hamet due to similar flat, rosetted habit and basally ascending inflorescence scape, but differs from that species in having well-pronounced, cuneate, eglandular petioles (3–)5–10 mm long (petiole 1–3(–5) mm long and hence leaves appearing almost sessile [“apetiolate”] in D. aliciae), in style arms entire or only shortly bifid in distal ⅓–¼ (style arms forking below middle, usually again bifid or tripartite in distal part) and fusiform seeds without terminal appendages (seeds narrowly fusiform with filiform appendage on micropylar and chalazal end).

...

Ecology and habitats — Drosera xerophila grows in Sandstone Fynbos vegetation over Table Mountain Sandstone, on well-drained ground in sandstone gravel, in cracks of sandstone rock, or in sandy soils with little organic matter (Fig. 2A, B). 

 ....

Etymology — The specific epithet denotes the fact that this species prefers to grow on well-drained, drier, only slightly moist ground (xerophilus = dry loving). This is not unusual for several species of Drosera from Mediterranean areas in the S hemisphere, but contrasts with the “conventional”, largely N-hemisphere-based experience of sundews as typical bog plants.
