C - Cryptocoryne Index



Natural hybrid. (= BOR?) "The South of Kalimantan is to date one of the most intriguing parts of Asia in respect to Cryptocoryne. It proves to be very difficult to set taxonomic boundaries between all new collected plants, for it seems that there is an almost continuous variation in characters in species like C. cordata var. zonata, C. cordata var. grabowskii, C. ´purpurea nothovar. borneoensis and C. edithiae."

"Three accessions of C. edithiae show rather defect pollen and there are no fruits known, what may indicate that C. edithiae is of hybrid origin. The fourth accession (I-SAKK1) is not in cultivation. The chromosome numbers for the plants however differ: Korthaus' plant had 2n = 68 (Arends et al 1982), the two others have 2n = 51 (Jacobsen unpublished), the fourth is unknown till now. C. edithiae can best be interpreted as a complex of hybrids where different parents may be involved, to be compared with C. ´purpurea nothovar. borneoensis. In Copenhagen DNA analysis is underway (Jacobsen priv. comm.)." - Bastmeijer

Cryptocoryne erwinii superficially resembles C. lingua in the leaves, but the leaf blade is more horizontally oriented, with the abaxial surface distinctly lighter than the adaxial one. The 6–9 cm long spathe is exceptional and differs from all other Cryptocoryne species in being white, with the distal part of the limb subulate and purple inside, first bent backward to upright, later bending forward over the white, widely expanded, funnel-shaped entrance, which lacks a collar. Its chromosome number of 2n = 26 has hitherto only been reported for the recently described C. aura.
