Interspecific Hybridization between Arisaema sikokianum and A. serratum (Araceae) Confirmed through Nuclear and Chloroplast DNA Comparisons
A morphologically intermediate plant between Arisaema sikokianum Franch. et Sav. and A. serratum (Thunb.) Schott has been newly found in Kochi Prefecture, Shikoku, Japan. The putative hybrid has the intermediate morphological characteristics of the parental species. Molecular analysis using PCR-RFLP of internal transcribed spacer (ITS) in nuclear DNA (nrDNA) indicates that the putative hybrid h...
متن کاملIntrogressive Hybrids of Arisaema sikokianum and A. tosaense (Araceae) Confirmed through Nuclear and Chloroplast DNA Comparisons
Morphologically putative introgressive hybrids of Arisaema sikokianum Franch. et Sav. and A. tosaense Makino were newly found in Kochi and Tokushima Prefectures in Japan. All the individuals have the same morphological characteristics as A. tosaense excluding a purple spathe. Molecular analysis using PCR-RFLP of internal transcribed spacer (ITS) in nuclear DNA (nrDNA) indicates that these putat...
متن کاملColocasia lihengiae (Araceae: Colocasieae), a new species from Yunnan, China
A new species of Colocasia Schott, C. lihengiae C. L. Long et K. M. Liu, sp. nov., is described and illustrated. The species is restricted to the rainforest of Xishuangbanna in southern Yunnan, China. Diagnostic morphological characters that distinguish the new species from the related species, C. fallax Schott, are discussed. Chromosome numbers (2n=28) were observed in plants of C. lihengiae c...
متن کاملEffects of forest age and disturbance on population persistence in the understory herb, <Emphasis Type="Italic">Arisaema triphyllum</Emphasis> (Araceae)
Long-lived understory herbs experience a highly dynamic forest over space and time, yet can persist for more than a century. To understand how these populations persist, we examined effects of forest age and disturbance on potential sexual reproduction and clonal growth in the sexually labile perennial, Arisaema triphyllum. Potential sexual reproduction female:male ratio was significantly great...
متن کاملPollen movement in a natural population of Arisaema serratum (Araceae), a plant with a pitfall-trap flower pollination system.
Arisaema serratum possesses a pitfall-trap flower pollination system. However, little is known about the efficiency and pattern of pollen movement in A. serratum. Thus, the aims of this study are to (1) determine the paternal parents of the seeds and (2) elucidate pollen movement in a natural population. Paternity analysis using microsatellite markers was performed. Seeds were collected from a ...
