sometimes inconspicuously so or glabrescent, triplinerved to subtriplinerved, midvein slightly 
sunken above, raised below, secondary veins rather flat above, slightly raised below, tertiary 
veins rather flat above and below, primary domatia in several pairs along midvein, rarely only 
basal pair present, secondary domatia, when present, just a few and not in all leaves; 
inflorescences (2) 5 - 15 cm long, single or clustered on short branches axillary to leaves, 
sometimes at the base of new shoots, peduncle, rachis, flower pedicel (2) 3 - 5 mm long, foliose 
bracts absent; flowers urceolate, greenish white, tepals 2 -2.5 mm long, ovate, usually pubescent 
outside, sometimes glabrous, sericeous inside, red hairs rarely present, stamens of whorls I & II 
1.5 - 2 mm long, filaments usually sericeo-pilose ad and abaxially, anthers glabrous adaxially, 
glabrescent or sparsely sericeous abaxially, sporangia four, stamens of whorl III 1.5 - 2.5 mm 
long, filament usually densely sericeous adaxially, red hairs present, anthers glabrescent to 
sericeous adaxially, glabrous abaxially, sporangia four, upper ones latrorse, lower ones latrorse- 
extrorse, glands ca. 0.5 mm long, at base of filament or slightly above it, staminodes 0.8 - 1 mm 
long, filament, usually sericeous ad and abaxially, head 0.5 - 0.7 mm long, triangular to cordate 
acuminate in outline, hypanthium 0.5 - 0.8 mm deep, pubescent to glabrous outside, usually 
densely sericeous inside, red hairs usally present, pistil ca. 1.8 - 2.5 mm long, ovary 1 - 1.5 mm 
long; fruit ellipsoid, cupule, tepals mostly persistent. 
C. triplinerve is, as circumscribed here, a very variable species. There are several groups 
identifiable on the basis of particular combinations of characters, but all of them have 
intermediate conditions that connect the groups in a way that is extremely difficult to draw the 
lines to recognize different taxa. Perhaps the only feature that keep together all the forms is the
