Amorphophallus kienluongensis is described as a new species from southern Vietnam. It is morphologically close to A. brevispathus Gagnep. (Thailand) and A. prolificus Hett. & A.Galloway (Thailand). However, it differs from both these species by a stigma with a central depression and an obconic male portion. So far A. kienluongensis is known only from the Kien Luong district of the Kien Giang province, southern Vietnam. The plant grows on limestone hills where its habitat is under threat owing to quarrying for cement manufacture. Therefore this species could be ranked as CR (‘critically endangered’) in the IUCN ranking. © 2016 Naturalis Biodiversity Center. Source

Amorphophallus natolii is described and illustrated as a new species from limestone hills near El Nido, Palawan island, Philippines. It differs most distinctly from other species of Amorphophallus with a densely hairy appendix by its much smaller size and dominant reddish pinkish colours of the spathe. A preliminary molecular analysis shows it to be in a basal position to a clade containing a few other species with similar appendices, to which it is also morphologically compared. It is certainly one of the most remarkable new discoveries in a genus containing ca. 200 species. Source

Background: Since the revision of Amorphophallus of Madagascar (Bot Jahrb Syst 121(1):1-17, 1999) several additional new species have been described. The recent discovery of another new species promted the preparation of a revised key as well as the description of the new species. Amorphophallus hildebrandtii, never restudied since its analysis by Engler in 1881, has been refound and restudied. Meanwhile molecular phylogenetic studies have provided new insights in the relationships of the endemic Madagascan species. Results: The new species Amorphophallus perrieri is described. A new revised key to the endemic Amorphophallus species of Madagascar is provided. An emended description of A. hildebrandtii is provided. A molecular phylogeny of the endemic Madagascan species of Amorphophallus is provided. Conlusions: The enigmatic character of a very short spadix in A. hildebrandtii has been confirmed, after it was thought for many years that it was artificially shorter in the holotype specimen than in nature. This was suggested by the fact that the spadix of the holotype is broken. The monophyletic character of the Madagascan endemic species clade remained unchallenged after analysis including all new species discovered recently, incl. the new species presented in this paper. © 2014 Hetterscheid and Claudel.

There are ten known species of Amorphophallus in the Philippines, and an eleventh is herein described and named as Amorphophallus adamsensis. It resembles A. dactylifer and A. rostratus. Diagnostic characters of this new species are provided. © 2013 Naturalis Biodiversity Center. Source

This study identifies Forsythia germplasm and evaluated the genetic relationships of F. ×intermedia hybrids, cultivars and their putative parental species. Leaf samples of F. ×intermedia cultivars and species, such as F. koreana and F. suspensa, were collected in the Netherlands, Korea, and USA. Total genomic DNA was extracted and evaluated by randomly amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) analyses. Dendrograms were constructed by using the neighbor-joining (NJ) clustering algorithm applying the interior branch (IB) test or analyzed by STRUCTURE. In the dendrogram generated by RAPD markers, two major clusters were observed. One cluster (CL-I) contained most of the F. ×intermedia cultivars, F. suspensa, and F. koreana. The other cluster (CL-II) included F. europaea, F. ovata, F. densiflora, F. mandshurica, F. japonica, F. viridissima, and cultivars derived from F. ovata. In the AFLP dendrogram, the placement of F. ×intermedia cultivars with F. suspensa was similar, forming cluster CL-A I. The RAPD and AFLP results clearly separated most F. ×intermedia cultivars from F. ovata derived cultivars. The full range of genetic diversity of F. suspensa and F. viridissima should be investigated to verify whether these two species are truly parental taxa for F. ×intermedia. Placement of F. viridissima, F. ovata, and F. japonica in different sub-clusters requires further investigation regarding genetic diversity in the species, and their close relationship with F. koreana, F. mandshurica, and F. saxatalis. © 2011 Springer Science+Business Media B.V.
