The single sheet of this species in the Berlin Herbarium bears the fol- 
lowing legend: — Cyrtandra Pickeringii ? A. Gray." The specific name 
Pickeringii was crossed out by Hillebrand and the name macrostegia was 
substituted for it. He also states: calyx corolla incurva paulla breviore, 
bracteis late foliaceis — trunco arboreo. July 1870." 
Cyrtandra macrocalyx is a distinct species, but Hillebrand's description 
of it is not quite correct, or rather the dimensions of leaf, petiole, peduncle, 
and pedicels are not the maximum dimensions actually occurring. The 
following dimensions may be supplied from a large series of specimens of 
this species: leaves up to 15 cm. long, serrulate to coarsely serrate, petioles 
up to 3.5 cm., peduncles up to 2.5 cm., pedicels up to 34 mm.; the texture 
of the calyx is thin rather than thick. The species is the common form on 
Molokai, where it grows on the exposed open ridges as well as in shaded 
ravines along stream beds. Those found in open places have the leaves 
more rounded and covered with a fulvous tomentum than those found in 
shady places; those of the latter locality have the leaves long and acuminate, 
of a fleshy texture, and of a greener color; the flowers are also larger. 
Cyrtandra umbracculiflora Rock n. sp. 
A stout shrub 3 m. high, the stems stout, with thick nodes, pubescent 
throughout; leaves (opposite?) alternate, large, ovate, acute at the apex, 
uneven-sided at the base, each side with a distinct sinus, the petiole ap- 
parently branching at the apex and forming a sinus on each side, 25 cm. 
long, 18 cm. wide, thick-chartaceous, the margin irregularly crenate to 
sinuately notched, the lobes with callous teeth at irregular intervals, hir- 
tellous above, tomentose beneath with yellowish-gray hairs, especially 
along the stout midrib and veins; petiole clasping, stout, 10-15 cm. long, 
densely yellowish-tomentose ; inflorescence yellowish-tomentose throughout, 
subumbellate, opposite to alternate, arranged along the stem, the common 
peduncle stout, flattened, 4.5 cm. long, 4 mm. broad, thickening and ex- 
panding subflabellately into two short thickened rays 5 mm. in length, each 
dividing again, pedicels of about even length, 13-15 in number, 3 cm. long; 
bracts subfoliaceous, lanceolate, acute to acuminate, 2.5 cm. long, i cm. 
broad; calyx irregularly lobed to near the base into broad, ovate-lanceolate 
segments acute at the apex, contracted below, indistinctly nerved, 12-15 
mm. long, 5-7 mm. wide, hirtellous to tomentose inside and outside, corolla 
unknown; fruit ovate-oblong, rounded at the apex, crowned by two-thirds 
of the style, the latter articulate in the last (upper) third; stigmatic lobes 
broadly ovate, with the margins reflexed.
