416 KANTIA. 
Var. inequifoliata. Albicans pellucida, caule ineequifoliato, nempe foliis 
altero caulis latere deficientibus vel ad squamulas bidentulas redactis. 
Folia ovato-ligulata exciso-bidentula. Foliola seepe dimidiata, dimidio 
altero (folio rudimentario subjecto) obsoleto, vel ad processulum 
subulatum redacto.—Hab. in terra umbrosa fluvii Uaupés. Folia, 
semper sat longa, inaliis exemplis subobovata, in aliis rectangularia 
fere videntur. In omnibus folia hic illic minora, diversiformia, vel 
altero caulis latere fere deficientia, altera magna, inveniuntur. 
C. Miquelit Mont., e descriptione cl. auctoris huic affinis erit ; 
quandoquidem folia “ rotundato-bidentata,” et foliola solum “bifida” 
(nec bis bifida) dicta sunt, pro diversa specie habituram censeo. 
K. Sprengelii Mart. certe differt foliis tam latis fere quam longis 
(nec subduplo longioribus, ac in nostra), cellulis subduplo brevi- 
oribus ; foliolis multo majoribus ; bracteis 3 ad 4 solum fissis, &e.

Elata pallide olivacea prostrata, matteolas latas tenaces efformans. Caules 
2-4-poll. vage divaricato-ramosi, radicellis validis repentes. 
Folia patula subplana vix decurvula, seepe per paria approximata, perpaulo 
imbricata, ex insertione fere longitudinali oblique ligulato-oblonga 
v. subrhomboidea, apice lato rotundata retusave; cellule magne 
elongato-hexagon leptodermes pellucidee subchlorophylosi. Folia 
superiora sensim multo minora, unde rami sepe lanceolati videntur. 
Foliola dissita foliis 5-7-plo breviora, oblata ad basin fere usque bipartita, 
lobis divergentibus seepe recurvis ovatis ovalibusve acutis v. obtusis. 
Fl. dioici: Q postici seepe fasciculati; bractez foliis plus duplo breviores 
erecto-patule ovato-oblong ; bracteole breviter bifidee. 
K. amazonica subminor est, albicans, tenerior, ramis haud divaricatis; 
foliis minoribus ovalibus emarginato-bidentatis; foliolis subminoribus 
bis bifidis. 
Subtribus V. SCAPANIOIDEZ:.
