Encephalartos Aemulans (Zamiaceae), a New Species From
S. Afr.J. Bot., 1990, 56(2): 239-243 239 EncephaJartos aemuJans (Zamiaceae), a new species from northern Natal P. Vorster Botany Department, University of Stellenbosch, Stellenbosch, 7600 Republic of South Africa Accepted 12 December 1989 Encephalartos aemulans Vorster is described from the Ngotshe district in northern Natal. It resembles E. natalensis R.A. Dyer & Verdoorn by the tuberculose bullae of the female cones, and E. lebomboensis Verdoorn by the relatively narrow leaflets which are reduced to prickles towards the base of the frond; but differs from both by the thick indumentum covering the cone surfaces, the sessile male cones without drooping beaks on the bullae, and by the morphological similarity between the submature male and female cones. Encephalartos aemulans word beskryf vanuit die Ngotshe-distrik in Noord-Natal. Dit stem ooreen met E. natalensis R.A. Dyer & Verdoorn op grond van die vratterige bullae van die vroulike keels, en E. lebomboensis Verdoorn op grond van die relatief smal pinnae wat reduseer is tot dorinkies na die basis van die blaar toe; maar dit verskil van beide deur die digte haarbedekking van die keeloppervlaktes, die sittende manlike keels waarvan die bullae nie afbuigende snawels vorm nie, en deur die morfologiese ooreenkoms tussen die byna volwasse manlike en vroulike keels. Keywords: Encephalartos, new species, Zamiaceae A critical study of Encephalartos natalensis R.A. Dyer & both ends, apices oblique and pungent, margins very Verdoorn led to the conclusion that plants from northern slightly revolute (more conspicuously so in dried than Natal represent a distinct and undescribed species: fresh material) with 1-3 teeth on upper margin and 1-2 on lower margin . -

The aim of the study was to test the hypothesis that Nothobranchius of the Malawi-Shire system constitute a separate evolutionary group from Nothobranchius kirki. Mitochondrial and nuclear sequence data show a strongly supported phylogenetic split into two monophyletic groups separating the Lake Malawi basin fish from N. kirki. Unlike N. kirki, Lake Malawi-Shire fish do not deviate from neutrality and express an excess of rare haplotypes and mutations in terminal branches, characteristic of recently expanded populations. Further, the two groups significantly differ in morphology. Two body characters (dorsal-fin base length and pre- pelvic-pre-anal distance) are significantly different between the two species in both sexes. Several other characters are significantly different in either male or female comparisons with respect to both standard and head lengths, and robust morphological differentiation is detected by multivariate analysis.
