[.—Tuer Hawanan Heparica or tHE TRIBE TRIGONANTHES. 
By C. M. Cooxs, JR. 
Tue tribe Trigonanthee is represented in the Hawaiian Islands 
by twenty-five species belonging to six of the twenty-six genera 
enumerated by Schiffner and by a single species of the genus Aero- 
mastigum recently proposed by Evans. None of the peculiar genera, 
such as Protocephalozia, Pteropsiella, Mytilopsis, Arachniopsis, 
ete., found in tropical America by Spruce, have representatives 
among the Hawaiian members of this tribe. The genera represented 
are Lepidozia (three species), Acromastigum (one species), Bazzania 
(ten species), Aantia (four species), Odontoschisma (three species), 
and Cephalozia including Cephaloziella (five species). 
Of the twenty-six species seven are unpublished—one in Lepi- 
dozia, two in Bazzania, and four in Cephalozia. ‘Three of the last 
belong to the subgenus Cephaloziella and one to the subgenus 
Eucephalozia. No species of Cephaloziella have before been 
reported from the Hawaiian Islands. 
A large number of the Hawaiian Trigonanthee are related to 
North American and West Indian species and apparently not so 
many to East Indian, Asiatic, or South Pacific species. Some of 
the Hawaiian species related to North American and European 
species are: Lepidozia australis to L. reptans, L. Hawaica to 
L. setacea, Bazzania Baldwinii to B. triangularis, Kantia bifurca 
to HK. Sullivantii, Odontoschisma Sandvicense to O. Sphagni, and 
Cephalozia Baldwinii to C. leucantha. ‘Two of those related to 
West Indian species are: Lepidozia Sandvicensis to L. commutata, 
and Bazzania patens to Mastigobrywn Cubense.  Cephalozia 
Kilohanensis is closely related to C. exilflora, of New Zealand, 
Bazzania emarginata is very close to B. fallax, of the Kast Indies, 
and Kantia Tosana is found in Japan. 
The larger species of Bazzania are very conspicuous in the woods 
and on the higher mountain-ridges. They form large mats on the 
ground, sometimes many feet in diameter, and also cover the trees 
along with other bryophytes. The writer has only collected on the 
islands of Oahu and the lower ridges of Kauai. Undoubtedly the 
high mountain ranges of Hawaii, Maui, Molokai and Kauai offer a 
very rich field for the hepaticologist, especially in the smaller forms. 
The conditions are most favorable for the growth of hepatics.
