Jansenella Bor (1955) (Gramineae, Arundinelleae) is a monotypic genus. It was previously only known from India, Sri Lanka, and Myanmar (Burma). However, Kerr collected it on 1 Feb. 1929, at Khao Pauta Luang Kaew, Ranong Province, at the boundary of the Khlong Nakha Wildlife Sanctuary, Peninsular Thailand (no. 16947). This collection was

Hal.) Bor. In 2001, this species was re-collected at the same location by A. Teerawatananon & S. Sungkaew (no. 2001–1). The occurrence of this species in Thailand is an interesting extension of the geographic distribution and is highly disjunct from previous reports of its
There is some confusion about the authorship of the species and the author abbreviation used. The article it appeared in was signed by “ C.Mull.”, however, there were several of that name who published around this period. One of the Griffith specimens we have examined in B, is labelled with “Herb. Karl Muller Hal.”. This is Johann Karl (Carl) August Muller (1818-1899). We have also received the important information from the library of the Botanic Garden and Botanical Museum Berlin-Dahlem, Berlin (BGBM), which confirmed that the full name of “C.Mull.” is “Carolo Muller”. We also found that “Carolo Muller” is the author of Synopsis Muscorum Frondosorum Omnium Husque Cognitorum in 1851, while Stafleu & Cowan (1981) reported that Johann Karl August Muller is the author of this book. This would lead us to the conclusion that the names “C. Mull.”, “Johann Karl August Muller”, and “Carolo Muller” are of the same person who is the author of Danthonia griffithiana (basionym of Jansenella griffithiana). This author is abbreviated “Mull.Hal.” (Brummitt & Powell, 1992). We therefore use this abbreviation for this species.
