 1917, E. 11. Wilso7i (No. 8277). 



This very interesting addition to the flora of eastern Asia is fairly com- 

 mon in open grassy places on all the islands which Wilson visited, and it 

 seems strange that it should have remained without a name. It had been 

 apparently first found by C. Wright according to a statement by Hillebrand 

 in his Flora of the Hawaiian Islands, p. 237 (1888), who mentions under 

 Lohelia Gaudichaudii Dc Candolle a specimen collected by Wright on the 

 Loo-choo Islands (apparently a mistake for Bonin Islands, for there is no 

 such Lobelia known from the Liukiu Islands) and says that it resembles the 

 present species (L. Gaudichaudii) greatly and that it is preserved in the 

 Harvard Herbarium, but there is now no Lobelia from the Bonin Islands in 

 the Gray Herbarium and none is mentioned In Dr. Gray's manuscript hst 

 of Bonin and Loo-choo plants. Our new species is undoubtedly near L. 

 Gaudichaudii y but that species has sessile leaves with a broad base and a 

 conspicuous row of resinous glands on the margins. 



At the last moment, when this article was already in press, we dis- 

 covered that Koidzumi had described and figured this Lobelia which we 

 had supposed to be an undescribed species in Matsumura's Icones Plant- 

 arum Koisikavenses.

 FAGACEAE 



Castanopsis Spach 



In the limitation of this genus I am following Schottky and unite the 

 section Chlamydubalanus Endlicher (sub Quercu; Oersted sub Pasania) 

 with Castanopsis. From Castanea the genus is easily distinguished by the 

 evergreen often entire leaves. From Lithocarpus it differs in the thin 

 cupula usually enclosing the nut entirely and splitting at maturity to liber- 

 ate it; the cupula is furnished with spines or tubercles arranged in usually 

 oblique zones, it is never covered by closely imbricate scales nor by con- 

 centric distinct rings; the number of flowers varies from 3-1 in a cupula. 

 The leaves are usually distichously arranged.
