6 MENISPERMACEAE, (Ranunculus. 
1. R. Mauiensis, Gray, Bot. U. S. E. Exp. p. 11, — A spreading, 
much branching perennial, 2—3 ft. long, pubescent, the branches fistular, 
but the stem solid. Lowest cauline leaves on long petioles of 1 ft. or 
more, ovate to deltoid in outline, 4—6/ in each diameter, trisected, the 
segments stipitate or not, deeply 2—3-lobed, the lobes obovate - acute, ir- 
regularly cut and serrate; the uppermost leaves sessile, trisected and at 
last ovate, subentire. Flowers small, single in the axils of the ultimate 
compressed, 1—1'/2“, shortly tipped with a suberect style, smooth an 
margined. 
On the higher lands of the whole group, from 2000 ft. upward; in Oahu on Mi. 
Kaala only. Forms with stipitate and sessile segments occur on all islands, the former 
probably growing at lower elevations. Specimens from East Maui and Kauai are 
ost hirsute. In leaf and fruit resembling forms of R. repens, but the flower much 
smaller. Native name: «Makou». 
2. R. Hawaiiensis, Gray, 1. c. p. 10. — Stout, erect, hirsute throughout, 
2—4 ft. high, with a fistulous stem. Lowest cauline leaves on long 
sharply cut-lobed. Flowers larger than in the preceding species, numerous, 
on grooved peduncles of 1—2‘, crowded at the end of the stem or branches 
in a subcorymbose inflorescence with bract-like leaves. Sepals 2—3”, 
colored. Petals 5—10, each 4—5” long, with a 2-cleft scale on the short 
claw. Achenes in ovoid heads, 1!/z—2" long, smooth, not margined, ending 
in a rather curved beak. 
Hawaii! and East Maui! from 4000 ft. upward. 
subterminal, but often incurved when mature, so that seed and embryo 
are bent into a crescent or ring. Fruit a drupe, with the endocarp pro- 
jecting on the ventral side. Seed peltately attached to the projection, 
either albuminous, with a central embryo, or almost without albumen, 
the embryo then thick and fleshy, with almond-like cotyledons. Radicle
