Rock: Notes ON HAWAIIAN LOBELIOIDEAE 237 
In the College of Hawaii Publications, Botanical Bulletin 2, 
the writer stated that Cyanea coriacea (Gray) Rock was a very 
variable species and that the racemes in J. Remy’s No. 302, pre- 
served in the herbarium of the Natural History Museum at Paris, 
were not fully developed. This number was collected on the 
island of Kauai, in 1852, and a duplicate specimen preserved in 
the Gray Herbarium served as the type of Delissea coriacea Gray 
(Cyanea coriacea Rock). The species is characterized by thick, 
leathery, long-petioled leaves and by very short and stout racemes: 
It has recently been collected by W. V. Hardy in the Waioli River 
Basin, Kauai, at an elevation of 5000-7000 feet, this being the 
second known locality for the plant. 
Another species of Cyanea, with racemes 7—22 cm. in length, is 
known to the writer from abundant material. It was originally 
collected by Hillebrand and referred by him to Delissea coriacea 
Gray. It was afterwards found by the Abbé Faurie and proposed 
as a new species by Léveillé under the name Cyanea Fauriei, the 
long racemes being emphasized in his description. This species 
is clearly distinct from Delissea coriacea and must stand as a good 
species. 
In certain respects C. Hard yi is intermediate between C. Fauriet 
and C. coriacea. It differs mainly in its leaves, which are linear- 
oblong and acuminate, tapering gradually into a margined petiole. 
It is further characterized by its habit and by its dark purplish 
black inflorescence. In C. Fauriei the leaves are obovate-oblong, 
with longer petioles and abruptly cuneate at the base, the petioles 
not being margined; the inflorescence is pale lilac and more robust. 
The following species, given in their natural order, range into 
each other and are consequently very closely related: C. coriacea, 
C. Fauriei, C. Hardyi, C. spathulata Rock, C. angustifolia (Cham.) 
Hillbrd., C. comata Rock, and perhaps C. Mannit Rock and C. 
obtustfolia Rock.
