CYRTANDREAE HAWAIIENSES 57 
bear the inflorescence along the lower part of the stem as well as in the upper 
leaf-axils. The leaves are only 7 cm. in diameter for the most part, but are 
as much as 10 cm. in width according to Hillebrand. The Lanai specimens 
must be referred to var. latifolia Hillebr., but they differ slightly from the 
Maui and Molokai specimens, mainly in the long (4 cm.) peduncle, 2-flowered 
inflorescence, large bracts, calycine lobes, and corolla. It may be termed 
a form of var. latifolia under the name forma grandis Rock n. f. 
Cyrtandra Grayana lanaiensis Rock n. var. 
A much branching shrub, the branches tortuous; leaves quaternate, 
elliptical, 5.5-10 cm. long, 10-24 mm. wide, acute-acuminate at both ends, 
the margin distantly denticulate to subentire, thick-chartaceous, hirtellous 
above, with a dense silky-brown tomentum beneath, on petioles of 1.5-2 
cm.; flowers single or three on a common peduncle of 10-25 mm., in the 
axils of the upper leaves, the bracts linear, acute; calyx lobes lanceolate, 
acute to obtuse, brown- tomen tose ; corolla hirsute; ovary glabrous; fruit 
elliptical, glabrous. 
Lanai: Summit ridge of Lanai, Haalelepakai, flowering and fruiting 
July 25, 1910, Rock no. 8036, in herb. College of Hawaii ; on largest mountain, 
flowering Sept. 21, 1916, A. S. Hitchcock no. 14662, in U. S. National 
Herbarium. 
This variety is a very handsome shrub and differs from the species and 
other varieties in the small elliptical leaves, short petiole, and short in- 
florescence, as well as in the smaller flowers. 
Cyrtandra Grayana nervosa Rock n. var. 
A shrub, the branches terete, sulcate when dry; leaves quaternate, 
elliptical-ovate to obovate-oblong, acuminate at both ends, denticulate 
excepting the base, thick-chartaceous, hirtellous above, glabrous below with 
the exception of the very prominently projecting midrib and lateral nerves; 
inflorescence a short, 3-5-flowered cyme; peduncle 1-1.5 cm.; corolla hairy 
or glabrate, with large lobes, the inflorescence otherwise the same as in var. 
latifolia: fruits elliptical-oblong, glabrous. 
Maui: West Maui, Puukukui, near the summit in dense shaded ravines 
and gulches, the branches covered with moss, flowering and fruiting Aug. 
22, 1910, Rock no. 8172 (type), in herb. College of Hawaii. 
This variety is at once distinguished from the others of the species by 
its leaves, which are glabrous underneath and expose the reticulated net- 
wr-i-; the midrib and secondary veins are strongly raised and silky brown- 
pubescent. In the other varieties, as var. latifolia and var. linearifolia, 
the whole under surface of the leaf is densely matted with a thick, brown, 
silky tomentum, which does not show the reticulate network. The plant 
occurs near the summit of west Maui, elevation about 5,000 feet, in the 
mossy forest; but tlie inflorescence is axillary instead of near the base of 
the stem.
