— This species is easily distinguished from the other species of Hespero-

which are not dentate. 
770. Lysimachia longisepala Ch. N. Forbes, l. c., p. 222, c. tab. — 
Folia ovata, acuminata, 11,5—15 X 5—6,5 cm, basi acuminata; petiolus 
tomentosus, 2—3 cm longus. Flores 2- 3, auxillaries; pedunculi tomen-

ovato-lanceolata, 1 cm longa, filamenta basi dilata, subconnata. Capsula 
crustacea, 16 X 10 mm. — Hawaii Islands: Flowering specimens 
were first collected when in the company of Mr. J. F. Rock during 
September, 1908, and eight months later fruiting specimens were col- 
lected in the company of Dr. C. M. Cooke and Mr. C. L. Thompson. 
The plant oceurs in wet woods of the Punaluu Mountains, Oahu. Ele- 
vation about 2300 feet. — The difference between this species and the 
other Hawaiian Lysimachias seems almost generic. It is unique among 
our species for having a longer calyx than corolla, and otherwise differs 
in its more cylindrieal flowers which are twisted tighter in the bud, and 
in its much larger leaves.
