Hibiscadelphus hualalaiensis (Malvaceae), 45243. From 

 Honolulu, Hawaii. Presented by Mr. Joseph P. Rock, 

 Botanist, College of Hawaii. A tree, 16 to 23 feet 

 high, with erect trunk, white bark, somewhat reniform 

 leaves, and small ovate capsules, belonging to the al- 

 most extinct genus, Hibiscadelphus, of the three species, 

 of which two are represented by a single tree each, 

 and the present one by a dozen or so living trees. 

 Seeds of all the species are growing, however, in 

 various Hawaiian gardens. This exceedingly interest- 

 ing and distinct species was found by the writer in 

 the year 1909 on the lava fields of Mt . Haulalai , in 

 North Kona, Hawaii, and in the forest of Waihou of 

 the same district, where about a dozen trees are still 

 in existence. The writer revisited the above locali- 

 ty in March, 1912, and found the trees in flower, 

 while on his previous visit, June 18, 1909, only a 

 few worm-eaten capsules could be found. The trees are 

 badly attacked by several species of moths which feed 

 on the leaves and mature capsules. Mr. Gerrit Wilder, 

 however, succeeded ingrowing a few plants from healthy 

 seeds collected by the writer. (Adapted from Rock's 

 Indigenous Trees of the Hawaiian Islands, p. 301.) 



Hordeum vulgare eornutum (Poaceae), 45366. Barley. From 

 Pretoria, Transvaal, Union of South Africa. Presented 

 by Mr. I. B. Pole Evans, Chief, Division of Botany, 

 Department of Agriculture. No. 18. A rust-resistant 

 barley from Fauresmith, one of the important wheat- 

 growing areas in the Orange Free State. 



Lawsonia inermis (Lythraceae) , 45250. Henna. From 

 Kerman, Persia. Presented by J. N. Merrill, Captain, 

 Commanding First Regiment of Cavalry, Persian Army. 

 A handsome shrub, probably native of northern Africa, 

 western and southern Asia, but widely cultivated in 

 tropical countries. The flowers are white, pink, or 

 cinnabar red, and are very fragrant. From the leaves 

 is produced the henna or alhenna of the Arabs ( Cyprus 

 of the ancients), a yellow dye which is used in Egypt 

 and elsewhere by women to color their nails, and by 

 men to dye their beards, and for similar purposes. It 

 is the camphire of the authorized version of the Bible.
