The genus Morinda (Rubiaceae) in Thailand

Abstract

The genus Morinda (Rubiaceae) is revised and presented with a key to species, descriptions with distributional and ecological data, together with illustrations of some species. Nine species are considered, one of which is divided into two varieties. Two species and one variety are endemic to the country. M. talmyi is typified. M. longifolia and M. pumila are reduced to synonymy with M. pandurifolia and M. tomentosa, respectively.

Review on Anthraquinones Isolated from Rubiaceae Family

“…The leaves are petiolate or subsessile with a stalked head of flowers that fuse together at their ovaries. The fruits were produced in ellipsoidal shapes that fused together known as syncarp (Kesonbuaa and Chantaranothai, 2013). Taxonomic studies in Malaysia have identified the Morinda genus as comprising nine species in Peninsular Malaysia, including three species with reported phytochemistry (M. citrofolia, M. elliptica, and M. umbellate), and six recorded species (M. corneri, M. lacunose, M. rigida, M. calciphila, M. scortechinii, and M. ridleyi) (Wong, 1984;Abdullah et al, 1998).…”

A new combination and typifications in Morinda (Rubiaceae) for the Flora of Thailand

“…In preparation for the upcoming Rubiaceae volumes in the Flora of Thailand, nine species were recognized in a recent publication (Kesonbua & Chantaranothai, 2013), and updates to this publication are presented here. Morinda pandurifolia Kuntze is now placed in synonymy under M. persicifolia Buch.-Ham., in agreement with the World Checklist (Govaerts et al, 2019).…”

“…Therefore, the new combination at species level is required. Pitard (1924) described Morinda persicifolia var. talmyi and cited M. talmyi Pierre mss.…”

“…36.1). Kesonbua & Chantaranothai (2013) selected Pierre 3217 at P as lectotype but this gathering has three duplicates (P04011606, P04011607, P04011608). The specimen P04011606 has more leaves and inflorescences and is selected here as the second-step lectotype (ICN Art.…”

Nectar robbing by sunbirds on the flowers of Morinda pubescens J.E. Smith (Rubiaceae)

“…are treated as synonyms to M. pubescens and accordingly this is followed in this work and the published work reported on these species is cited as related to M. pubescens. M. tomentosa which is now known as M. pubescens is widely distributed in India, Sri Lanka, China, central Myanmar, southern Thailand, Vietnam, and Indonesia (Kesonbuaa & Chantaranothai 2013). It is a small evergreen tree adapted to grow successfully in arid/semi-arid to mesophytic conditions (Bermer & Manen 2000).…”
