Type locality, near the Waliiawa swamp, on the slopes of 

 Kahili, Kauai. Specimens first collected by Mr. J. M. Lydgate a 

 number of years ago. C. N. Forbes, No. 259, K. August, 1909. 



A tree 75-90 dm. high. Leaves elliptical to cuneiform, serrate 

 on the upper two-thirds, lower third generally entire, scabro pubes- 

 cent, 5-6 cm. long, 2.5-3.5 cm - wide; with pubescent petioles of 

 .5-1 cm. long. Flowers solitary in the axils; with pubescent 

 peduncles, articulate near the top, 1.5-2 cm. long. Involucral 

 bracts lanceolate, pubescent, 11 mm. long. Calyx pubescent, 

 tubular, marginate, shortly dentate, 2.5-2.7 cm. long. Petals ob- 

 long-spatulate, red, pubescent on the outside, 6.5 cm. long, 11 mm. 

 wide. Staminal column 5 cm. long. Styles hirsute, 9 mm. long. 

 Capsule unknown. 



This species differs from H. kokio Hillebr. in its pubescent 

 calyx, and in other minor characters. A red hibiscus growing on 

 Hauopu, Kauai, although very different in habit, has flowers very 

 similar, and is probably a variety. Another specimen, originally 

 from Napali, which has been under cultivation a number of years 

 in Mr. Lydgate's garden at Lihue, Kauai, is probably another 

 species, or distinct variety. It has much shorter involucral bracts, 

 and a wider corolla of a different shade of red. As I have never 

 seen it in its native locality, I hesitate to describe it at present. 

 I observed still another form, growing on the cliffs near Kalalau, 

 which I was unable to obtain, which had a staminal column which 

 protruded beyond the petals.
