Hello Sean,
Budianto is the author who described C. ideii (translation of the article:
http://www.nationaalherbarium.nl/Cry...ii_English.doc). I usually omit the author's name(s) since this invariably leads to confusion but if need be you can always find this info behind the scientific name on Jan's crypt pages ...
Those B numbers are Jan's own catalog numbers - better write them Bast.1064, etc.; the whole provenance may look like this (that was one of the plants I gave you at the last ECS meeting): *yourself* <- Witte (KEW 5111) <- Jacobsen <- Bastmeijer (Bast. 1064) <- Idei (A-09).
This plant does not come from the type locality and has been referred to as C. cf. ideii since its exact identity still needed to be proven.
BTW, in Sabah I collected a member of the Betta unimaculata species group from a swamp at sea level just adjacent to the beach...
Bast. 1088 is indeed the green clone from Sekadau (NT 0405); Bast. 1087 is the brown clone from the same locality (NT 0404). This crypt (both clones) is pretty much intermediate between ideii and ferruginea AFAIK. A very nice crypt...
I prefer to use the original collector's code when identifying a given crypt but Jan's code is also widely known.
