Cyrtandra polyantha ambigua Rock n. comb. 
Cyrtandra triflora Hillebr., var. 7 ambigua Hillebr. Fl. Haw. Isl. 332. 1888. 
Leaves 8 cm. long, 2.5 cm. wide, acuminate at both ends, closely dentic- 
ulate, coriaceous, on petioles of 2 cm.; peduncle 8 mm., pedicels several of 
variable length, glabrous as is the calyx; calyx one-half or two- thirds the 
length of the corolla, cylindrical, shortly and unevenly divided to less than 
the middle into lanceolate-acute lobes or teeth, beaked in the bud and split- 
ting laterally; corolla cylindrical, hirsute, the lobes small. 
Oahu: Hillebrand in herb. Berlin and herb. College of Hawaii. 
Hillebrand's var. ambigua of h's C. triflora is exceedingly close to C. 
polyantha and almost identical with it, but still worthy of varietal rank. 
As it does not belong to C. triflora Gaud, but to C. polyantha C. B. Clarke, 
it is here referred to it as a variety. Hillebrand gives no other locality 
than Oahu. The writer has not collected this variety. 
ADDENDA SECTION CYLINDROCALYCES 
Cyrtandra limosiflora Rock n. sp. 
Single-stemmed, bearing a crown of leaves at the apex, 1-1.5 m. high; 
stem stout, 5 cm. in diameter near the base, distinctly nodose, the nodes at 
intervals of 2.5-3 cm., greenish-gray; leaves large, quaternate, sessile, 
forming a large rosette-like crown, chartaceous, broadly lanceolate-oblong, 
acuminate at the apex, gradually tapering from the middle of the leaf to a 
broad sessile base, 45-50 cm. long, 10-12 cm. wide (2-2.5 cm. wide at the 
sessile base), the margin denticulate, sparingly so towards the base, dark 
green above, pale grayish-brown beneath, glabrous above, puberulous to 
glabrous below but somewhat pubescent along the midrib and veins; 
inflorescences densely crowded around the stem for a length of 14-20 cm., 
surrounding the stem at each node and in the axils of the leaves; peduncle 
3-5 mm., bearing about ten flowers; pedicels about 4 mm.; calyx pale green, 
cylindrical, puberulous outside, densely hirsute with long hairs inside, about 
2.5 cm. long, bilabiate, unequally deeply slit into four lobes with long fili- 
form apices; corolla the length of the calyx, slightly curved, glabrous 
throughout, the lobes unequal, oblong, rounded; style glabrous, the stig- 
matic lobes large, ovate-oblong; fruit ovoid-oblong, glabrous. 
MoLOKAi: Mapulehu Valley, Pukoo, among rocks in stream bed, 
flowering December 24, 1915, Rock no. 12522, type in College of Hawaii 
Herbarium. 
A remarkable species, resembling in habit a Cyanea. The name 
limosiflora refers to the slimy inflorescence which is usually full of insect 
life, slugs, and decayed vegetable matter and gelatinous substances. It is 
related to Cyrtandra longifolia var. degenerans C. B. Clarke, but differs 
from it in the very large, broadly sessile leaves and numerous inflorescences 
which extend down the stem for sometimes 20 cm. It belongs to the section 
Cylindrocalyces, from which it was omitted by an oversight. 
In Halawa Valley on the same island (Molokai) there occurs a Cyrtandra 
with very large leaves which resemble those of C. limosiflora but are dis-
