Malvaceae. 



This also accounts for the publication of a Hibiscus Fan rid by Leveille, coming 

 from the mountains behind Honolulu, where the tree is quite common. In order 

 to straighten matters out the writer sent specimens to the Gray Herbarium to be 

 compared with Asa Gray's type. Dr. B. L. Kobinson kindly replied as follows: 

 "There can be no question that the white flowered species (no. 8831) from Oahu 

 is precisely the real H. Arnottianus Gray. 



"The red flowered species (a photograph was sent) as far as can be made out 

 from the photograph corresponds very well with authentic material of H. Kokio 

 Hbd. ; the chief difference being the larger petioles. ' ' This, however, may be 

 due to the fact that the plant was grown in cultivation ; it came from the garden 

 of Mr. Gerrit P. Wilder. This now settles the controversy in regard to one 

 of the most beautiful native flowering trees which the Islands possess. Along 

 streambeds in the mountains of Koolau, Oahu, it is usually a tree 30 feet tall 

 and when in flower makes a beautiful display. It is also cultivated by residents 

 of Honolulu. On the other islands it is not uncommon, but varies to some 

 extent. A pure white flowered one occurs on the beach of Wailau Valley, on 

 Molokai. 



Hibiscus Waimeae Heller.

HIBISCUS WAIMEAE Heller in Minnes. Bot. Stud. Bull. IX. (1897) 851, pi. 53. Hibiscus 

 Arnottianus Gray forma Mrs. Sinclair Indig. Flow. Haw. Isl. (1885) pi. 8. 



Leaves suborbicular about 5 cm or more in diameter, pale green, crenate, pubescent 

 on both sides, velvety to the touch; petioles half the length of the leaves; stipules small; 

 flowers axillary near the ends of the branches, large white or tinged with pink, on 

 pubescent pedicels; calyx broadly tubular, pubescent outside, woolly within, petals 10 to 15 

 cm long, 18 to 25 mm wide, prominently veined, pubescent on the outside; staminal column 

 rather stout, long exserted, red, otherwise as in H. Arnottianus Gray. 



This rather distinct plant occurs as a tree 20 to 30 feet in height on the 

 leew r ard side of Kauai below the forests of Kaholuamano at the bottom of vertical 

 cliffs, in dry situations, and in gulches on open grass lands below Halemanu, 

 Kauai, at an elevation of 2500 feet up to 3000 feet, in company with Dracaena 

 aurea, Osmanthus sandwicensis and others. It is also cultivated now in Ho- 

 nolulu.
