Comments

Hotta provisionally classified M. campestris into two subspecies, subsp. campestris and subsp. glabra. but this was never formally published and can be ignored.   For the record, in coresspondence with Markku Häkkinen, Hotta noted that subsp. campestris "is distributed around Kuching, western part of Sarawak, with hairy peduncle" and subsp. glabra " is distributed eastern Sarwak, Brunei and Sabah with glabrous peduncle".

Markku Häkkinen has identified five geographically delimited varieties of M. campestris in northern Borneo:

M. campestris var. campestris
M. campestris var. lawasensis

M. campestris var. limbangensis
M. campestris var. miriensis

M. campestris var. sabahensis
M. campestris var. sarawakensis


Although he had not seen the plant Cheesman (1950 s) comments that from its description it must be very similar to M. violascens.  Simmonds comments on the small size of its seeds which he gives as 6 x 2 - 3 mm.
