flowered; bracts about 6 mm., acute; pedicels 10-12 mm., the lateral ones 
shorter; calyx 7-10 mm., including the linear lobes, the latter more or less 
spreading; corolla hirsute outside toward the apex; the tube slender, ex- 
serted, nearly twice as long as the calyx, ampliate at the throat; ovary 
glabrous but hirtellous at the base of the style, the latter reddish-hirsute.

Clarke was certainly a keen systematist; he correctly separated Cyrtandra 
kalichii Wawra occurring in the western range from plants growing at much 
lower elevations in the eastern range, for which plants he adopted Hille- 
brand 's manuscript name C. tristis. Hillebrand classed both of these 
plants together and records his C. tristis as a synonym of C. kalichii. There 
are certainly decided differences between these plants; the most striking 
is in the petiole, which in C. kalichii is winged, or the leaf is decurrent about 
to the middle of the petiole, which is then naked. In C. tristis the petiole 
is much stouter and shorter and is broadly winged to the clasping base. 
The corolla tube is nearly twice the length of the calyx and is narrow and 
slender and also exserted; in C. tristis the corolla tube is not exserted; in 
fact the whole corolla is almost included, only the spreading lobes being 
free. In C. kalichii the calycine lobes are spreading, while in C. tristis the 
calyx is cylindrical, with the lobes erect. The leaves of C. kalichii are ovate 
to suborbicular, the margins are coarsely dentate and the teeth again serru- 
late; in C. tristis the leaves are obovate to ovate-oblong, and the margin is 
denticulate only. However, the plants are very closely related, and it is 
perhaps better to report Clarke's C. tristis as a variety of C. kalichii Wawra. 
Hillebrand writes C. Kalihii instead of Kalichii as Wawra spells it; the 
former spelling is correct. Wawra identified the aspirated Hawaiian h 
with the German ch, hence his improper spelling.
