'Tab. nostra XIII. 
Calyx 5- (rarius 4-2-) fidus vel fere partitus, mediocris aut majus- 
culus (nisi in sect. Microchiritâ); lobi acuti, in æstivatione valvati. 
Corolla medioeris aut magna (nisi in sect. Microchirità), tubuloso- 
infundibuliformis aut tubuloso-ventricosa, 2-labiata, labio superiore 
2- inferiore 3-lobo, lobis omnibus rotundatis. Stamina 2 perfecta, 2-2 
sterilia; filamenta fertilia complanata, genieulata; antheræ circa 
stigma conniventes aut cohærentes ; loculi 2 ovati, divaricati, rimis 
in unum confluentibus. Discus annularis. Ovarium liberum, lineare ; 
stylus brevis vel elongatus; stigma junius oblique peltatum in mar- 
gine uds fissum, dcs mano Re vex phique procurrens, 
bifidum, i tis lamella 
ampliate, subpersistentes ; placentæ admodum intrusæ, in facie inte- 
riore approximatæ, nudæ, deinceps recurvatæ, ovuliferæ. Capsula 
linearis, elongata (5 cm. aut ultra), sessilis aut saltem in stipite quam 
calyx haud longiore sustentata, per totam longitudinem secus 2 lineas 
loculieide dehiscens, proventu ab apice usque ad basin 2-4-valvis; 
placentæ valvis rectis affixæ, recurvatæ semina integentes. Semina 
ellipsoidea levia, nec marginata neque appendieulata, utrinque umbo- 
nata aut a processu minuto terminata, sæpe longitudinaliter striata, 
testa reticulata, levis. 
Herbie raro metrales (C. acuminata interdum 2-metralis). Folia 
opposita sæpe inæqualia, verticillata aut alterna, elliptica aut ovata 
rarius lanceolata. Pedunculi axillares, longi vel breves, multi- vel 
pauci- imo 1-flori; bracteæ liberæ vel connatæ, parvæ aut mediocres, 
deciduæ. 
Species 25, in India, Burma, China, Sumatra et Java; in udis sylvis 
in montibus prsecipue lectæ. 
Genus a Didymocarpo ope nullius boni signi distingui potest. Hoc 
loco species ad Chiritam attributz (nisi sect. Mierochirita) calyce 
corolla capsula longioribus gaudent. Discrimen R. Brownii « Stigma 
in Didymoearpo integrum, in Chiritá bifidum » non omnino valet. 
Sect. Microchirita, a Benth. et Hook. f. inter Chiritas dubie collocata, 
a Dalzellio ad Didymocarpum relata est.
