CYRTANDREAE HAWAIIENSES 
collection. There is no doubt that the writer's plant is identical with 
the description. It is larger in every way than the species, the leaves are 
certainly the size of C. Macraei and even larger, but the calycine lobes are 
long and linear to almost subulate. It is an intermediate between C. Mac- 
raei and C, gracilis, or C. gracilis is a variable species with larger leaves in 
shaded situations and smaller ones in open or exposed forest ridges. 
Cyrtandra Macraei A. Gray. Proc. Amer. Acad. 5: 352. 1862 
A shrub about 3 m. high or more, the branches strictly quadrangular, 
subherbaceous, green, with a pruinose efflorescence towards the apex; 
leaves broadly ovate, opposite, 15-22 cm. long, 10-15 cm. wide, acuminate 
at the apex, rounded or slightly decurrent at the base, thin-membranous, 
glabrate above, canescent underneath with a faint pubescence, the margin 
dentate to the base; petiole stout, pruinose, 5-14 cm. long; inflorescence a 
subumbellate, pruinose cyme, axillary in the upper leaves and extending 
some distance down the stem, in the fleshy ascending branches axillary in 
the lowest leaves; flowers numerous, ten to twenty, on a common peduncle 
of 5-6 mm., the latter branching into, or bearing at its apex, three rays, 
each bearing a number of slender pedicels of variable length, those with 
fertile flowers reaching a length of 8 mm. ; calyx parted to near the base into 
acute or acuminate, lanceolate lobes 2-3 mm. in length; corolla tube of even 
width, slender, curved, 12 mm. long, 3 mm. wide, with small pruinose lobes; 
ovary pruinose, elliptical; style articulate at or below the middle; fruit 
oblong, rounded at both ends, 12 mm. long, 7 mm. wide when fully mature.

Cyrtandra Macraei is exceedingly close to C. gracilis, but differs from it 
in the short calycine lobes, shorter corolla, and numerous flowers. 
Cyrtandra Macraei parvula Rock n. var. 
A small tree or shrub 3 m. high, with numerous slender, angular branches, 
pruinose towards the apex; leaves ovate-oblong, caudately acuminate at 
the apex, cuneate at the base, bright green and puberulous along the nerves 
and leaf-base above, grayish to canescent below, and pubescent, especially 
along the midrib and nerves, thin-chartaceous, denticulate excepting the 
base, 10-15 cm. long, 5.5-8 cm. wide, on petioles of 3.5-6.5 cm.; inflores- 
cence densely crowded in the axils of the upper leaves, pruinose, the peduncle 
3-4 mm.; pedicels 5 mm.; flowers numerous, glomerate; calyx 3 mm., in- 
cluding the lanceolate lobes; corolla 8 mm , white-pruinose in the bud, little 
less so when mature, berry elliptical, acute, 6-8 mm. long.
