40 Directors Annual Report, 



Ivysimachia longisepala, sp. nov. 



Folia ovata, acuminata, 11.5-15X5-6.5 cm., basi acuminata; petiolus 

 tomentosus, 2 3 cm. longus. Flores 2 3, auxiliaries; pedunculi tomentosi, 

 2-,; cm. longi; calyx l<>l>is 6 8, Lanceolatis, 2.5 cm. longis; corolla ovato- 

 lanceolata, 1 cm. I011.ua. filamenta basi dilata, subconnata. Capsula Crus- 

 tacea, 16 X 10 mm. 



A suffrutieose plant six inches to three feet in height, usually 

 unbranched, the new growth being tomentose with purplish hairs, 

 becoming glabrous with age. Leaves very dark green above, 

 paler beneath, ovate, acuminate, 4.5-7.5X2-3.5 inches, the base 

 narrowing into a tomentose petiole of 22 lines. Flowers pendu- 

 lous, one to three in the axils of the upper leaves, on tomentose 

 peduncles 9-14 lines long. Calyx green, marked with deep purple 

 veins, and tomentose on the back with purple hairs, its deeply 

 parted seven (6-8) lanceolate lobes longer than the corolla, ir 

 lines. Corolla colored as the calyx, its lobes ovate lanceolate, 

 minutely serrate, 5 lines long. Stamens less than one half the 

 length of the corolla, filaments dilated at the base, sub-connate. 

 Style about the length of the corolla. Capsule bottle-shaped, 

 thick, crustaceous, 8 lines long, 5 lines in diameter, tipped by the 

 style of 8 lines in length. 



Flowering specimens were first collected when in the company 

 of Mr. J. F. Rock during September, 1908, and eight months later 

 fruiting specimens were collected in the company of Dr. C. M. 

 Cooke and Mr. C. L,. Thompson. The plant occurs in wet woods 

 of the Punaluu Mountains, Oahu. Elevation about 2,300 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 cylindrical flowers which are twisted tighter in the bud, and 

 in its much larger leaves.
