Oahu : Waianu Valley, windward side of the Koolau range, near 
the head of the valley, along stream-bed, flowering, Jan. 22, 1909, 
Rock, type no. 1 167 in herb. College of Hawaii. 
A very interesting and striking species, remarkable for its large 
leaves, which are sessile. The species is single stemmed and at first 
glance resembles some of the Hawaiian Lobeliads, especially species 
of the genus Rollandia, in whose company the plant grows. 
It is related to Cyrtandra longifolia var. degenerans and its forms.

of leaves at the apex, not unlike a species of Cyanea; leaves 45-55 
cm. long, including the thick, winged petiole, 22.5-35 cm. broad; mid- 
rib fleshy, obovate, rounded at the apex, suddenly narrowing below 
into a margined petiole, the latter 1.5 cm. thick, texture of leaves 
thick, but coriaceous to fleshy, upper surface deeply rugose, the 
veins impressed, dark green, lighter underneath, glabrous, dull; 
young leaves and petioles covered with a light silky brown tomentum, 
with erose margins, the young leaves almost fringed; flowers numerous 
in subsessile clusters surrounding the stem, and hidden; calyx with 
prominent veins, curved, yellowish brown, five-cleft, bi-labiate, the lower 
lip consisting of two sepals, 12 mm. long, suddenly narrowing into 
filiform apices, the upper lip of three sepals half as long as lower lip, 
the two outer ones only beaked, all parts covered with a silky brown 
tomentum; corolla enclosed in the calyx, white, 36 mm. long including 
the 25 mm. long tube, slightly curved, two upper petals rounded and 
smaller than the three lower which are acute, pubescent; stamens

Kauai: Forests of Kaholuamano, elevation 4,000 ft., on cliffs, 
near streams or waterfalls, along the trail of the Waialae Valley, 
flowering March 3, 1909, Rock, no. 2282 in herb. College of Hawaii. 
One of the most striking species of Cyrtandra. It resembles a 
species of Cyanea of the section Palmaeformes, hence the specific 
name. The native name of this species is Mapele.
