Notes
There are plants that have a general habit intermediate between C. javanicum and C. lanceolatum, between C. javanicum and C. furcatum as well as between C. javanicum and C. timorense. The delimitation of the species is still far from clear, and it may prove neccessary to divide it into several subspecies, as geographical correlations seem to exist in many case, or even into several species. On the other hand, C. timorense and C. hellwigii may prove as mere subspecies, though at the moment the differences seem to be constant.
Specimens from the Tengger Mts, E Java, have remarkably narrow leaves and small nutlets with a distinct rim formed by the bases of marginal glochids. Specimens from Bali and Lombok (only one seen from each) are very untypical with more patent, rough indument and may represent a local subspecies.
