Notes
USES. None recorded on specimens from our area. CONSERVATION Least Concern (LC); widespread. There are 3 plants on a sheet at K with ‘type sheet’ written on it possibly in Bentham’s handwriting. All are from Madagascar: the first collected by G.W. Parker in Aug. 1880, the middle one without a collector’s name on a cut out label giving the name of the country only (Madagascar), and the third collected by R. Baron in July 1880. As the new species was published in 1836, neither of the two collections dated 1880 can be the holotype of Diclis ovata. In the protologue Bentham cites a specimen fom Madagascar which he has seen, but does not give the name of the collector or a collection number. It is quite probable that the middle specimen is one of Bojer’s collections from Madagascar, of which a couple are at P, and I have seen them. The specimen at K is definitely the holotype, however it cannot be said if those of Bojer’s at P are isotypes.
