Hawaii: Woods of Kohala, rain forests at an elevation of 4,000 feet; 
flowering and fruiting June 10-16, 1910, Rock no. 8361 (type), in herb. 
College of Hawaii (Plate HI). 
This new species is very near C. Me^iziesii Gray, but differs from it 
in the coriaceous, velvety-tomentose leaves, the robust habit, and much 
larger calycine lobes. 
Cyrtandra kohalae is apparently related to C. platyphylla, from which 
it differs, however, in the oblong, long-acuminate leaves, but especially in 
the subulate-linear calycine lobes and small flowers. It is at a glance 
distinguishable from C. platyphylla by the spreading, 2-cm.-long calycine 
lobes; the tube of the calyx is exceedingly short. This species seems to 
link together the sections Crotonocalyces and Schizocalyces. The appear- 
ance of leaf as well as habit of plant would place this species in the former 
section were it not for the distinct calyx. 
Cyrtandra halawensis Rock n. sp. 
A tall shrub, 3 m. or more high; leaves opposite, elliptical to ovate- 
oblong, acute at both ends, 13-30 cm. long, 7-14 cm. broad, thin-mem- 
branous to chartaceous, hispidulous above, silky-brown tomentose beneath, 
the margins serrate-dentate excepting the slightly uneven-sided base, this 
merging into a petiole of 2.5-1 1 cm.; inflorescence axillary, a 3-flowered 
cyme, yellowish-brown tomentose throughout, the common peduncle 
1.5-2.5 cm. long; bracts linear-lanceolate, acute, 5-12 mm.; pedicels of 
variable length in the same cyme, 4-20 mm. long; calyx lobes linear, 2 cm. 
long, 2-3 mm. wide, long-acuminate; corolla as long as the calycine lobes or 
Icvss, of even width, curved and hairy in the upper third; ovary conical- 
oblong, glabrous, the style articulate below the middle, stigmatic lobes 
oblong; fruit ovate-oblong, acute, 15 by 10 mm., glabrous. 
MoLOKAi: Forests of Halawa Valley on the plateau above the falls, 
along stream bed and the outskirts of forest, flowering and fruiting April 
1910, Rock no. 7010 (type), in herb. College of Hawaii (Plate IV). 
Cyrtandra halawensis, while not so distinct a species as C. umbracculi- 
flora, is sufficiently distinct to be classed as a species. It is true that it 
comes close to C. Grayana var. latifolia Hillebr., but differs from it in the 
very large, long, linear calycine lobes; the leaf margins are serrate-dentate, 
while those of C. Grayana are subentire. 
Cyrtandra macrocalyx Hillebr. Fl. Haw. Isl. 329. 1888 
Cyrtandra macrostegia Hillebr. mss. (in Gray Herbarium). 
Arborescent, 4-5 m. high, the branches moderately hirsute; leaves in 
whorls of four, elliptical-oblong, acuminate at both ends, serrulate, 10-12. 5 
cm. long, 3.75-4.5 cm. wide, on petioles of about 12-18 mm., thick-char- 
taceous, with prominent veins, sparingly hairy above, with a faint ferrugi- 
nous tomentum beneath; peduncle 8-16 mm., bearing one or two flowers on 
pedicels of 12 to 14 mm., the bracts large, fohaceous, ovate, 12-24 mm. long,
