Two new species of Asteraceae (tribe Anthemideae, subtribe Pentziinae) from the Cape Floristic Region of South Africa are described. Marasmodes schlechteri Magee & J.C.Manning, a local endemic from the lowlands between Piketberg and the Olifants River Mountains, is distinguished by its spreading leaves with axillary fascicles and relatively large, solitary capitula with obconical involucre borne on very short lateral shoots. Pentzia trifida Schltr. ex. Magee & J.C.Manning is a well-collected limestone fynbos endemic that is readily distinguished by the regularly trifid leaves, broadly cyathiform involucres with lanceolate to oblanceolate bracts, and the well developed pappus extending the entire length of the relatively short corolla tube.  相似文献

The new species Caesia sabulosa Boatwr. and J.C.Manning from deep sands along the West Coast of South Africa and sandy flats in the Cederberg and Bokkeveld Escarpment is described. It is distinguished by its extensively branched rhizome resulting in a robust, clump-forming habit, and unique ‘palisade’ root system of closely packed, hard, vertical roots; mostly larger flowers; erect fruiting pedicels; and details of the seed testa sculpturing.  相似文献

The genus Psednotrichia (Asteraceae–Senecioneae) is endemic to Angola and currently consists of two annual species, P. xyridopsis (O. Hoffm.) Anderb. & P. O. Karis, and P. newtonii (O. Hoffm.) Anderb. & P. O. Karis. A perennial member of the genus was collected on a recent field trip to Angola, and is here described as P. perennis N. G. Bergh & B. Nord., sp. nov. A key to the three species is provided.  相似文献

Combretum stylesii O.Maurin, Jordaan & A.E.van Wyk, a liana or slender tree with scrambling branches from the Tugela River Valley (KwaZulu-Natal), South Africa, is described. Molecular data supports its placement in subgenus Combretum section Ciliatipetala with its closest relative Combretum edwardsii. The new species differs from C. edwardsii in having, amongst others, a single mature leaf form, leaves softly textured, with whitish hairs, often with drooping habit, shorter leaf petioles (less than 5 mm), and less complex 8-celled leaf scales. A key to the species and infraspecific taxa of section Ciliatipetala in the Flora of southern Africa region is provided.  相似文献

The new species Polhillia ignota Boatwr. is described. This species is known only from two collections, one between Vredenburg and Saldanha and the other close to Porterville. The new species is most similar to P. obsoleta, which is known only from a few localities around Worcester, in its narrow, sericeous leaflets and flowers of equal size, but differs in its flattened mature leaves with larger leaflets (up to ± 12 mm long), longer pseudo-peduncles (up to ± 15  mm long), denser inflorescences (with up to four flowers), shorter pedicels (1–2 mm long) and non-auriculate wing- and keel petals.  相似文献

Othonna cerarioides Magoswana and J.C. Manning is described as a new species from Namaqualand, Northern Cape Province of South Africa. It is an erect shrub with rod-like stems and branches, bearing numerous spur-shoots with obovate-oblanceolate leaves clustered at the tips, and up to nine disciform capitula per spur-shoot. Othonna cerarioides is anomalous in the genus in that the style of some of the disc florets is bifid. Othonna is diagnosed within subtribe Othonnineae by female-sterile disc florets with simple (or very rarely minutely bifid) styles. The disc florets in the closely related genus Hertia are bisexual with well branched styles.  相似文献

Two new Coecobrya species, which were newly collected in 2014, are described from China. Coecobrya sanmingensis sp. n. from southeast China (Fujian) is the fourth 1+1 eyed species in the genus; it can be distinguished from other three species by the ciliate chaetae X and X2-4 on the ventral side of head, the abundant chaetae on the trochanteral organ, a large outer tooth on the unguiculus, the absence of smooth manubrial chaetae, and the dorsal chaetotaxy. Coecobrya qinae sp. n. from southwest China (Yunnan) is characterized by paddle-like S-chaetae of Ant. III organ, ciliate chaetae X, X2 and X4 posterior to labium, medial macrochaetae on the mesothorax, and 5+5 central and 2+2 lateral macrochaetae on the fourth abdominal segment. An updated key to the Chinese species of Coecobrya is given.  相似文献

The phylogeny of the genus Brachyglottis suggests that its constituent species should contain pyrrolizidine alkaloids. Consistent with this hypothesis, and the established occurrence of such alkaloids in Brachyglottis repanda, Brachyglottis kirkii, and Brachyglottis hectori, an investigation of Brachyglottis adamsii revealed the presence of senecionine and retrorsine; Brachyglottis huntii was found to contain senkirkine and retrorsine; 7-O-angelylheliotridine was the predominant alkaloid in Brachyglottis perdicioides, and the same alkaloid together with senecionine, senkirkine and intergerrimine was present in the Brachyglottis hectori × B. perdicioides “Alfred Atkinson” horticultural hybrid; Brachyglottis sciadophila contained clivorine and neopetasitenine (acetylfukinotoxin); the latter alkaloid was also present in B. kirkii together with the previously reported senkirkine and senkirkine 12-acetate.  相似文献

A new species of scorpion of the genus Neoscorpiops Vachon, 1980 is described from Northern Maharashtra. Neoscorpiops maharashtraensis sp. nov. is a medium-sized scorpion species ranging from 36 to 42 mm. Carapace, mesosoma and metasoma brown, legs and telson yellow; pedipalp in a shade of brown with carinae dark drown to black. Granulation on carapace coarse, with a few smooth patches; on mesosoma, which is restricted to the posterior half. Anterior margin of carapace with a moderately deep “U”-shaped emargination medially lacking elevated edges. Pectines well developed 7/7. Trichobothria on patella ventral 13–16. Pedipalp chela narrow and elongate in males, length-to-width ratio in males is 4.86–5.05.  相似文献

A new orchid, Disa albomagentea, is described from the Hottentots Holland Mountains in the Western Cape Province of South Africa. It is an obligately fire-dependent species closely related to Disa obtusa (sect. Disella), from which it can be easily distinguished by the larger flowers, i.e. galea 7-9 mm long versus 4-7 mm long, which are patent and bicoloured, i.e. magenta, white and not spotted versus purple brown, white to cream to greenish, and variously purple spotted. It appears to be endemic to seeps and marshes on the high peaks.  相似文献

The new species Pelargonium elandsmontanum is a local endemic from Elandsberg Nature Reserve near Malmesbury in the Western Cape Province, South Africa. One of six species of sect. Hoarea with just the posterior two petals developed, it resembles P. ternifolium in its trifoliolate leaves and pink petals but is distinguished from that species by the short, stout petioles, rhombic, acute leaflets with the upper surface glabrous or with spreading hairs (vs cuneate, apically incised leaflets with both surfaces adpressed-hairy), and five (vs four) fertile stamens.  相似文献

Three new species of the genus Trachyandra are described, T. hantamensis Boatwr. & J.C.Manning, T. kamiesbergensis Boatwr. & J.C.Manning and T. sanguinorhiza Boatwr. & J.C.Manning. These species form part of a group of morphologically similar species referred to here as the T. thyrsoidea group and are distinguished by their generally small stature, filiform leaves (except for T. tortilis), and simple or shortly branched racemes of patent flowers with maculate tepals. Many of the species in the group have roots that contain abundant anthraquinones, visible as a red substance below the outer skin of the roots, and which is soluble in alcohol, thus often staining herbarium papers purple. A synopsis of the eight species that comprise the T. thyrsoidea group is presented, with maps of each species and illustrations of those described as new.  相似文献

A new high-elevation scorpion species of the genus Scorpiops is described from the Indian state of Himachal Pradesh. Scorpiops spitiensis sp. nov. is the second highest-elevation scorpion species in Asia and the first one from India occurring at elevations above 4200 m. The new species closely resembles Scorpiops petersii, but it can be distinguished from it based on a suit of characters, one of which is the presence of 16 trichobothria on the external aspect of the patella, which is unique to the new species.  相似文献

A highly localised new species from the Cederberg Mountains near Wuppertal in the Western Cape Province is described. Annesorhiza asparagoides B.-E. Van Wyk, collected for the first time in 2009, differs from all other species of Annesorhiza (and the closely related Chamarea) in the unusual leaf structure, with crowded, subsessile, acicular leaf segments, resulting in dense, bottlebrush-like pinnae. The new species has a cluster of 10 or more slender roots, small (< 150 mm long), sparsely hairy leaves and small (± 8 mm long), oblong, conspicuously ribbed, homomericarpic fruits.  相似文献

Taxonomic considerations are given for the genus Lissothus Vachon, 1948 (Scorpiones, Buthidae). Two species are currently known, Lissothus bernardi Vachon, 1948 from Libya and Lissothus occidentalis Vachon, 1950 from Mauritania. In this contribution, a new species, Lissothus chaambi sp. n., is described from the desert of Central Algeria. The new species is most closely related to L. bernardi. The geographical distribution of the genus is discussed.  相似文献
