 chartaceous, entire, 12 to 25 cm long, 3.5 to 7 cm wide; inflorescence a terminal corymb", 

 when fully developed 15 cm long, standing erect on a common stiff peduncle of 8 cm, 

 densely covered with a long stellate woolly tomentum, calyx densely tomentose, divided 

 to the middle into ovate acute lobes of 4 mm length, corolla parted two thirds its length 

 into ovate-oblong acute lobes, which are of a blue color, and glabrous inside, but densely 

 tomentose outside, with a prominent median nerve; stamens on short filaments, anthers pale, 

 short, oblong, not attenuate, broader at the apex than at the base, 2.5 mm long, with two 

 ovoid apical pores; ovary villous, style long protruding, 6 mm, hairy; berry globose, black 

 covered with a short stellate pubescence when young, 10 to 12 mm in diameter on pedicels

This most remarkable species was discovered by the writer on the Island of 

 Oahu in the lower forests near Waiahole, at the entrance of Waianu Valley, 

 on January 22, 1909 ; only a single tree was seen, for which an old native gave 

 the name as riiananakonua. He remarked that he knew of the tree when he 

 was a boy, and that his parents used the fruits for medicinal purposes. 



This is the only species of Hawaiian Solanum which becomes a tree, all the 

 rest of them being shrubs. It is remarkable for its large entire leave?, but 

 mainly for its terminal woody corymbose inflorescence which reaches a length 

 over 15 cm ; also for the bright blue corolla, and long filiform style. 



It is named in honor of Ex-Governor George R. Carter, who made the publica- 

 tion of this volume possible. 



Collected at Waianu, Oahu, flowering and fruiting, January 22, 1909, (no. 

 1191), type in the College of Hawaii Herbarium. 



myoporaceae:. 



The main regions of the distribution of this family are situated in Australia 

 and in the neighboring islands. Only a few out of the 102 species are found 

 outside of Australia, one each in China and Japan, one in Mauritius, one m 

 South and West Africa, and another species in the West Indies. Here in the 

 Hawaiian Islands we have also only one species represented. The family con- 

 sists only of 4 genera, nearly all Australian. 



MYOPORUM Banks at Sol. 



Calyx 5-lobed, unchanged at maturity of the fruit. Corolla with short tube sub 

 campanulate, or with longer tube and funnel shaped, actinomorphous. Stamens 4, two 

 large, rarely 5. Ovary 2 to 10 celled; and as many seeded. Trees or shrubs or bushes 

 with erect and prostrate stems. Flowers single or fasciculate in the leaf-axils. 



The genus numbers about 25 species, which are divided into 5 sections. It is 

 distributed over Australia, China, Japan, Mauritius and the Hawaiian Islands 

 with a single species which comes under section II. Polyeoelium. 



The only useful species of Myoporum are M. platycarpum R,. Br., the sandal 

 or sugar tree or dog wood of the Australians, which exudes a sort of manna, and
