A. W. Evans — Hawaiian Hepaticm of the Tribe Jubuloidece. 407 



one third to one half with acuminate lobes and acute sinus, entire 

 or sparingly ciliate-dentate (with one or two teeth) on the sides; 

 leaf-cells rather thick-walled with small but distinct trigones and 

 occasional, vague, intermediate thickenings: $ inflorescence borne 

 on a px'incipal branch with innovations on one or both sides, the 

 innovations themselves usually floriferous and innovating on one 

 side; bracts in a single pair, the lobe ovate-oblong, narrowed into a 

 long, acuminate point, entire or sparingly ciliate-dentate (with one or 

 two teeth), lobule ovate-lanceolate, long-acuminate, entire (the stylus 

 apparently obsolete) ; bracteole ovate, free from bracts, bifid about 

 two fifths with acuminate lobes and acute sinus, markedly narrowed 

 toward base, entire or with one or two cilia near apex; perianth ob- 

 ovate, gradually narrowed toward base, rounded or truncate at apex 

 and narrowed into a short beak, with a high, narrow, postical keel, 

 smooth : $ spikes long and slender, arising singly or in pairs near the 

 involucre and in the position normal for vegetative branches; bracts 

 in six or more pairs, smaller than the stem-leaves, complicate-bilobed 

 and concave, imbricated but not densely so, the lobes ovate and 

 acuminate, lobules smaller, ovate, acute; bracteoles similar to the 

 other underleaves but smaller. 



Stems 0.2'"" in diameter, lobes of leaves 1.1x0.8"™, lobules 

 0.3x0.2"'", underleaves 0.6 x 0.65'""", leaf-cells at edge of lobe 13/a in 

 diameter, in the middle 25 x H/x,, and at the base 32 x 19/a, lobe of 

 bract 1.7x0.7'"", lobule 1.1x0.5"", bracteole 1.7x1"", perianth 

 2.4-2.9"" long, 0.95"" wide. 



On the ground and on trunks of trees in damp places. West Maui

Although the present species was considered distinct by Austin, 

 Schiffner* accords it specific rank very doubtfully, and Stephanif 

 reduces it to a simple synonym of Jubida Ilutchinsice. The follow- 

 ing characters, hoAvever, would seem sufficient to distinguish it: its 

 leaf-lobes are usually entire except for the apical tooth, which is 

 longer and slenderer than in J. Hutchinsice; when other teeth are 

 present, they too ai-e slender ; the lobule does not end in a slender point, 

 but is constricted and truncate at the mouth; the bracts and brac- 

 teoles are larger and less toothed (frequently not toothed at all) and 

 are tij^ped with slender points; the 3 branches are long, extending 

 far beyond the stem-leaves, and they arise in the same way as ordi-
