over the whole lower surface, glabrous above, ovate or elliptical-oblong, 
IO-20 cm. long, 5-10 cm. wide, on petioles of 2.5-8 cm., caudately acuminate 
at the apex, serrulate, suddenly contracting and shortly decurrent; flowers 
generally three or five to seven, on a common peduncle of about 15 mm.; 
pedicels slender, 2-5 cm., thickening above; bracts linear-lanceolate, 6-12 
mm.; calyx glabrate, spHt to the base into linear lobes 12-18 mm. in length, 
shorter than, or equaling, the corolla; corolla pruinose, slightly curved or 
suberect, 25 mm. long, ampliate at the throat; ovary glabrous, elliptical, 
the style hirtellous, slender; stigmatic lobes obovate, spreading; mature 
fruit 22 mm. long, 5 mm. broad, narrow-oblong, acute, sessile. 
Oahu: near Palolo (on both mountain ranges), not uncommon in 
Nuuanu; Konahuanui gulch, Hillebrand, in herb. Kew and BerHn and 
Gray Herbarium, co-type in herb. College of Hawaii; Punaluu Mts., Koolau 
range, along stream beds, flowering Dec. 3-14, 1908, Rock nos. 325, 7421, 
762, in herb. College of Hawaii (Plate VH). 
Cyrtandra gracilis is somewhat variable; the specimens from the Punaluu 
mountains have a stout quadrangular stem and not a slender one, and the 
leaves are larger and have a close fenestrate venation; the petioles are also 
stouter, and the peduncles are shorter. Hillebrand states "flowers generally 
three"; his specimens have nearly all from six to seven flowers; the calycine 
lobes which, he remarks, are generally longer than the corolla, are usually 
only one half the length of it. His variety suhumhellata seems to be only a 
large form of the species, but owing to its extraordinary size is here retained 
as a variety. 
The specimen in the Gray Herbarium has the leaves more elliptical- 
oblong and the exceedingly long pedicels measuring over 5 cm., while the 
peduncles vary from i to 2 cm. 
The long slender calycine lobes exceed the fruit, but do not quite equal 
the flowers in length.

Habit of the species; branches stout quadrangular, with stout nodes at 
the places of leaf attachment; leaves large, broadly ovate, caudately acumi- 
nate at the apex, decurrent at the base for a short distance, 22-31 cm. long, 
10-18 cm. wide, thin membranous, chartaceous, dark green above, grayish- 
puberulous underneath, with prominent nerves; margins broadly dentate 
excepting the base; petiole 3.5-7 cm. long; inflorescence axiflary, extending 
down the stem; the common peduncle 1.5 cm. ,* flowers six to eight on slender 
pedicels of 12-25 mm.; bracts numerous, linear, up to 17 mm. long; calyx as 
in the species, the lobes linear, as long as the corolla or shorter; corolla
