Calocedrus rupestris Aver., H.T. Nguyen & L.K. Phan was described in 2008 based on some morphological characters that were not sufficiently significant to discriminate it as a species distinct from C. macrolepis Kurz. We applied a new approach to resolve these conflicting views by using sequence data from DNA (ITS) to elucidate phylogenetic relationships between the two species. Analyses of a partial ITS1 sequence in 5 individuals of 2 subpopulations of C. macrolepis and 18 individuals of 8 subpopulations of C. rupestris collected in Vietnam were done. Molecular characterization of the two species showed its low divergence with the lack of autapomorphic characters. In addition, the ITS1 partial sequences of some C. rupestris individuals were identical with C. macrolepis. Due to the less distinctive morphology between C. rupestris and C. macrolepis, the divergence between them does not exceed the interspecific levels, and therefore, C. rupestris could not be regarded as an independent species in relation to C. macrolepis but only as one of its varieties, C. macrolepis var. rupestris (Aver., H.T.

A new species of Primulaceae, Primula hunanensis G. Hao, C. M. Hu & X. L. Yu, from Hunan, China, is described and illustrated. Based on its general morphology it clearly belongs to P. sect. Carolinella, characterized by the calyptrate capsules, but can be distinguished by its adaxially glabrous leaves which are much longer than the petioles, blade base broadly cuneate to subrounded, umbellate inflorescence, and glabrous pedicels and calyx. 相似文献

A new species of Primulaceae, Primula wawushanica G. Hao, C. M. Hu & Y. Xu, from Sichuan, China, is described and illustrated. In general morphology it is clearly allied to P. sect. Petiolares subsect. Davidii, characterized by firmly papery or leathery leaves, with adaxially impressed veins which are often prominently raised and alveolate abaxially. However, from other species of this subsection, P. wawushanica is distinguished by its glabrous and sessile leaves, smaller flowers, and by the shorter scape at flowering time. 相似文献

A new species of Primulaceae, Primula persimilis G. Hao, C.M. Hu & Y. Xu, from Sichuan, China, is described and illustrated. In general morphology it is allied to the species of P. sect. Monocarpicae, characterized by the presence of multi‐cellular hairs, the distinctly petiolate leaves, a campanulate calyx, and a globose or cylindrical capsule with valvate dehiscence. The new species superficially resembles P. tsiangii W.W. Smith, but can be distinguished by its white flowers, longer calyx lobes, and cylindrical capsules. 相似文献

A new species of Primula, P. vallicola Y. Xu, G. Hao & C.M. Hu, is described and illustrated from Sichuan province, China. Based on general morphology the new species is assigned to Primula sect. Aleuritia subsect. Yunnanensis. It is closely allied to P. kialensis, but can be distinguished by its larger stature, leaf shape, and the well‐differentiated petiole. The leaf shape of the new species is ovate to ovate‐elliptic and usually sub‐rounded at base. The new species also resembles P. homogama, but differs in being glabrous rather than with appressed hairs, and with longer petiole. 相似文献

The name Lithocarpus longinux (Hu) Chun ex Y. C. Hsu & H. W. Jen is reinstated. It used to be treated as a synonym of L. areca (Hickel & A. Camus) A. Camus, but morphological characters of cupules and leaves support the reinstatement. These two species, together with L. longzhouicus (C. C. Huang & Y. T. Chang) J. Q. Li & L. Chen, make up a small group that is distributed in limestone areas and have similar morphological characters. A key is provided to distinguish between them, and their is discussed. 相似文献

Artabotrys manoranjanii M. V. Ramana, J. Swamy & K. C. Mohan (Annonaceae), a new species from the foot hills of Saddle Peak National Park, north Andaman Islands, is described and illustrated. Its fleshy petals and prominent stigmas, distinguish it from all previously known species. Its affinity with A. parkinsonii Chatterjee, a Myanmar species, and A. grandiflorus King, a species from Malayan peninsula, is deliberated. 相似文献

Calathea dorothyae J. M. A. Braga & H. Kenn. sp. nov. from the sandy coastal plains of southeastern Brazil is described and illustrated. It is apparently endemic to the ‘Cabo Frio Center of Plant Diversity’, and it is considered ‘Critically Endangered’ (CR). The new species is somewhat similar to C. reginae J. M. A. Braga and C. sphaerocephala K. Schum. with which it is compared. 相似文献

Annulatascus joannae, A. lactus, and A. tropicalis are described and illustrated from decaying woody substrata in freshwater habitats in Hong Kong. Annulatascus joannae is distinguished by ellipsoidal and thick-walled ascospores whereas A. lacteus has milky ascomata and A. tropicalis has relatively large, fusiform, 1–3-septate ascospores. Annulatascus biatriisporus is reported as a new record in Hong Kong. A key to and a synoptic table of Annulatascus species are provided.

Four species of Mastigostyla (Iridaceae) from Bolivia are described, illustrated and maps of their distribution provided: M. cardenasii R. C. Foster, M. chuquisacensis Huaylla & Wilkin, M. torotoroensis Huaylla & Wilkin and M. woodii Huaylla & Wilkin, the last three as new species. Mastigostyla gracilis R. C. Foster is synonymised under M. cardenasii R. C. Foster. Notes on conservation status, nomenclature and identification are included. Although some uncertainty exists
over generic placement due to phylogenetic systematic research now in progress, marked infraspecific variation is documented
for the first time within South American Tigridieae. This draws attention to the need for more extensive sampling if adequate
species delimitation is to be achieved in Tigridieae. Photographs illustrate morphological variation in all four species.
A key is provided to facilitate identification of Bolivian Mastigostyla. 相似文献
