Three new species of Amorphophallus from Asia are described. Their morphological similarities to other species are discussed.
Amorphophallus is a genus of 239 species distributed across the African, Asian, and Australian continents. A new species, Amorphophallus bantae, from the Sa Kaeo province of Thailand is described and illustrated. The species is compared to morphologically similar species in the Longituberosus and Saraburiensis subclades and an updated key to these...

Fourteen new species of the genus Amorphophallus are described from SE Asia, based mainly on material in existing living collections. The affinities of the species to existing ones are discussed.
Amorphophallus ravenii V. D. Nguyen & Hett., a new species of Araceae, is described from material collected in Vang Vieng District, Vientiane Province, Laos. This species is similar to A. khammouanensis A. Galloway and A. croatii Hett. & A. Galloway, but differs by having an appendix about half the length of the male zone, stigmas about 1.5 times a...

... In particular, Yuzami (2018) informs that A. paeoniifolius is a terrestrial herb; tuber depressed globose, dark brown with root-scars prominent, c. 30 cm in silence; petiole c. 2 m long, surface somewhat corrugate to strongly echinate-verrucate, pale to dark green or blackish green with large and small pale blotches and numerous tiny dark dots; leaf blade c. 3 meters in silence, highly dissected; inflorescence with short peduncle; spathe campanulate limb spreading strongly undulate. Hetterscheid and Mangelsdorff (2006) explain that this plant has a peduncle much shorter than spathe, rounded or conical appendix; petiole rough; tuber with distinctly raised, annulate root scars. Kurniawan et al. (2011) inform that the plant has characteristics of tuber diameter of 25 cm and up to 30 cm, dark brown, rough with several nodes, and producing seasonal rhizomatous buds. ...
Mutaqin AZ, Kurniadie D, Iskandar J, Nurzaman M, Husodo T. 2021. Morphological characteristics and habitat conditions of suweg (Amorphophallus paeoniifolius) around Mount Ciremai National Park, West Java, Indonesia. Biodiversitas 22: 2591-2600. Indonesia is a country that has abundant biodiversity, especially the diversity of plant species. One of the plant species that widely distributed across Indonesia is Amorphophallus paeoniifolius (Dennst.) Nicolson, or locally known as suweg. This study aims to identify morphological characteristics of A. paeoniifolius and its habitat conditions around Mount Ciremai National Park, West Java Province, Indonesia. Several stages of the exploratory survey were randomly carried out followed by purposive intensive observations. The method used to collect and analyze data is qualitative methods combined with simple measurements of quantitative technique. The results showed that suweg in the studied areas had distinctive morphological characteristics, which are different from the rest of the species from Amorphophallus genus. The plant is found in 4 types of land, namely home gardens, gardens, rice fields, and pond edges, whether with open or closed canopy conditions. The density of suweg in the study area is generally low. The climatic and edaphic conditions of suweg habitat in several study areas showed that there are a lot of similarities of conditions with other references. There are also 156 species of plants found that grow around suweg, both in the category of cultivated and wild plants. This- study enriches the existing knowledge on the botanical and ecological information of A. paeoniifolius in the context of geographical area (i.e., Ciremai National Park, West Java, Indonesia).
... This species differs from all others on Madagascar in flowering alongside the leaf late in the rainy season. Hetterscheid and Mangelsdorff (2006) published two new species from Madagascar, A. erythrorrhachis Hett., O. Pronk & R. Kaufmann and A. andranogidroensis Hett. & Mangelsdorff. ...
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.
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.
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.
