The Genus Lagenophora in the Hawaiian Islands, 
with Descriptions of New Species. 
CHARLES N. FORBES. 
OCTOBER, 1918. 
THE first Hawaiian representative of this small genus of the 
Composites was discovered by Horace Mann on the summit of 
West Maui where it is still a common plant. It also occurs on 
Eke, a small isolated crater to the west of the summit peak Puu 
Kukui,’ but has not been reported from elsewhere. Two unde- 
scribed species, noted below, occur in bogs on Kauai, while per- 
haps these or others may eventually be found in bogs on Molokai, 
East Maui and Hawaii. ‘The habitats of the Hawaiian species are 
the open bogs of the humid rain-forests at elevations of 4,000 to 
6,000 feet. The rainfall in these localities varies from 200 to 600 
inches per annum with some rain or fog practically every day in 
the year. 
While on Eke I noticed two forms of ZL. maviensts Mann which 
at first sight seemed to be distinct varieties, but further study in 
field and herbarium shows them to be simply variations of a single 
species. The species and forms may be described as follows:

‘In conversation with Rev. J. M. Lydgate I learn that the Eeka locality 
of Dr. Hillebrand is the point now generally known as Puu Kukui, and so 
recorded on the official maps. This fact is of considerable importance to the 
student of Hawaiian botany because the two localities have similar though 
slightly different floras. Keka is given by Hillebrand as the type locality for 
some of his species, while in reality Puu Kukui is the place where the plants 
were collected. It is practically impossible to reach Eke from Puu Kukui; 
and I very much doubt if Hillebrand ever visited the locality. There may be 
some question as to whether Eke and Keka are the same place.
