Molecular characterization of Calocedrus rupestris Aver., H.T. Nguyen & L.K. Phan, 2008 (Cupressaceae) based on ITS1 partial sequence

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. Nguyen & L.K. Phan) L.K. Phan, Long K. Phan & Aver.     

Primula hunanensis sp. nov. (Primulaceae) from Hunan,south–central China

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.

Primula persimilis sp. nov. (Primulaceae) from Sichuan,China

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.

Reinstatement of the name Lithocarpus longinux (Fagaceae)

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.

A new entomopathogenic nematode, <Emphasis Type="Italic">Steinernema robustispiculum</Emphasis> n. sp. (Rhabditida: Steinernematidae), from Chumomray National Park in Vietnam

Steinernemar robustispiculum n. sp. (Rhabditida: Steinernematidae) was isolated from woodland in Chumomray National Park, Sason, Sathay, Kontum, Vietnam. Its morphology, morphometrics, cross-hybridisation and the ITS-rDNA sequence analysis revealed that S. robustispiculum clearly differs from other known Steinernema spp. As in the cases of S. intermedium (Poinar, 1985), S. robustispiculum has very robust spicules, but it can be distinguished by the longer tail of the infective juvenile, lower E%, shorter spicules, the shape of the spicules, the number of genital papillae in the caudal region and the presence of a mucron on the male tail. S. robustispiculum has a lateral field resembling that of S. sangi Phan, Nguyen & Moens, 2001, but can be distinguished by a higher E%, higher D%, smaller length to width ratio of the spicules and the morphology of both the spicule head (manubrium) and the dorsal lobe of the spicule. The morphometrics of infective juveniles of S. robustispiculum are similar to those of S. monticolum Stock, Choo & Kaya, 1997; these species can be distingusihed by the position of the excretory pore, the smaller length to width ratio of the spicules, and the length and morphology of the spicule head (manubrium). The phylogenetic relationships within Steinernema Travassos, 1927, including the newly sequenced Vietnamese species S. robustispiculum n. sp., S. loci Phan, Nguyen & Moens, 2001, S. thanhi Phan, Nguyen & Moens, 2001 and S. sangi, are presented based on analyses of the ITS-rDNA. The ITS RFLP profiles obtained from 17 different restriction enzymes are also presented.     

Primula vallicola sp. nov. (Primulaceae) from Sichuan,China

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.

Pathak sect. nov. is established and revised based on morphology, and found to include four species: D. gaoligongshanensis from west Yunnan, D. arunachalensis Lidén & M. K. Pathak sp. nov., endemic to central Arunachal Pradesh, D. grandifoliolata (syn. D. ventii) and D. paucinervia (K. R. Stern) Lidén & M. K. Pathak comb. nov., the two latter species widespread in the east Himalayas.
