“…Some genera (Dz$oro@is, Goniosyfiha, Heteropolygonatum, Kiuntheria and Theropogon) were not included in the morphological analysis due to insufficient micromorphological data. Heteropo&gonatum is probably closely related to Pobgonatum (Tamura et al, 1997a). A broad view was taken of some other genera, although this may need more work; for example, Beaucarnea is here included in Nolina (Mabberley, 1987).…”

“…The bootstrap was used to evaluate internal support; we used 250 replicates with TRB swapping and a tree limit of 20 (to reduce the time spent swapping on replicates with large number of shortest trees).

“…Verticillata (x = 13, 15). Heteropobgonatum has x = 16 chromosomes (Tamura et al, 1997a). The karyotype in Ruscaceae sensu stricto is based on x = 20 submedian chromosomes of \.arying sizes (six pairs of long submetacentric chromosomes and fourteen pairs of short submetacentric chromosomes: Sat6, 1942; 2n = 40 or 80: Sen, 1978;Taniura, 1995).…”

Heteropolygonatum ginfushanicum is an endemic epiphytic herb in China. The complete chloroplast (cp) genome of H. ginfushanicum is reported in this study. The total length of the cp genome is 155,508 bp with a typical quadripartite structure consisting of a large single copy region (LSC) of 84,552 bp and a small single copy region (SSC) of 18,528 bp, separated by a pair of 26,214 bp inverted repeats (IRs). It encodes a total of 113 unique genes, including 79 protein-coding, 30 tRNA, and four rRNA genes. Phylogenetic analysis indicated that H. ginfushanicum is sister to Heteropolygonatum marmoratum within subfamily Nolinoideae.

Additionally, their base chromosome number is x = 16 and is distinctly bimodal vs. the lower, although variable basic chromosome number and asymmetric karyotype in Polygonatum, x = 9-15 (Deng et al 2009, Tamura & Xu 2001, Yamashita & Tamura 2001, Tamura et al 1997a.…”

New names in Heteropolygonatum (Asparagaceae)

Heteropolygonatum has been considered endemic to China, but molecular analyses and morphological observation of type and living collections necessitate the transfer of several Polygonatum to the former: Heteropolygonatum alternicirrhosum, H. anomalum, H. marmoratum, and H. parcefolium, which expands the range of the genus to neighboring Vietnam where H. marmoratum has been collected. Discussion of their morphology, perigone images, distribution, and full synonymy are given for the species transferred herein. Discussion of the distinctive generic morphology and karyotypes are provided in relation to their generic placement. Furthermore, the expansions of the provincial distributions of H. ginfushanicum and H. roseolum are given based on examination of herbarium material. A synoptic key to the genus is provided.
