Rock: New HAWAIIAN PLANTS 135 
of 2,400 feet. The largest plant seen was thirty feet in height. 
The plants are difficult to see in the forest as the trunk, which is 
usually covered partly with moss, does not branch and the crown 
of leaves is hidden amongst the foliage of other trees. 
Cyanea Giffardii may be Hillebrand’s 6 var. of his Cyanea 
arborea from the woods of Hilo, Hawaii. The writer is well ac- 
quainted with Cyanea arborea and can only state that the new 
species is exceedingly different from the latter, and that it comes 
much closer to Cyanea superba. Cyanea arborea has a much 
larger and denser crown of leaves, which are sessile, and linear- 
oblong; the peduncles are much longer and the flowers are very 
thin, narrow and slender, suberect and whitish to gray. 
2. Cyanea rollandioides sp. nov. 
Plant I-1.5 m. high, stem simple, fleshy towards the apex, 
woody towards the base, stem muricate to spinose in the upper 
portion; leaves obovate-oblong, acute, fleshy when fresh, papery 
when dry, dark green above, paler underneath, but with dark 
purple midrib and veins and a prominent dark purple reticulate 
network, puberulous or glabrous on both surfaces, but more or less 
covered with spines on both sides, those of the upper surface yel- 
low, those of the lower surface deep purple, margins eroso-dentate 
to irregularly notched, and somewhat uneven-sided at the base, 
30-50 cm. long, 8-15 cm. wide in the widest portion, which is in 
the upper third, on fleshy stout spinose or muricate petioles, 8—1 5 
cm. long; racemes glabrous, peduncle 3-6 cm. long, naked three 
fourths its lower length, but distantly covered with scars of fallen 
flowers, bearing in its upper fourth about fifteen flowers; bracts 
subulate, 3 mm. long, supporting each pedicel, the latter filiform, 
10-25 mm. long, bibracteolate, the bracteoles alternate, one at 
about the middle of the pedicel the other near the apex, 0.25 mm. 
long; calyx tube turbinate to obovate-oblong, 7-10 mm. high, the 
linear calycine lobes as long as the tube; corolla deep purplish red 
or purple to pale yellowish white with dark purplish streaks, 
moderately arcuate, broadest at the middle, 5-8 mm., about 4-5 
cm. long, thin and glabrous, dorsal slit very shallow, extending 
only one fourth of the length of the tube or a little beyond the two 
upper linear subulate lobes, the three lower lobes a little shorter; 
staminal column glabrous, as are the pale greenish anthers, the 
lower ones only penicillate; fruit unknown.
