This species seems sufficiently distinct from any of the oth- 

 ers by the leaf shape alone, although Mann, in Proc. Am. Acad. 

 7: 170, says "the only characters upon which this species can 

 be kept distinct from the first (kaduana) are, so far as the 

 specimens now show., the slightly longer tube of the corolla, 

 which is bearded within." It is very likely that some of the 

 specimens which Mann cites are not of this species, but belong 

 to another. The original is clear enough, and one who has ob- 

 served these plants in the field, should have no great difficulty 

 in deciding to which of the two species enumerated above his 

 specimens belong. The original description says: "Folia in 

 apicibus conferta, elliptica, utrinque acuta, apice tamen obtusi- 

 uscula * .* * maxima 3£ poll.-longa, 1£ poll, lata, petiolo 

 ad summum semipollicari, lamina decurrente marginata." My 

 No. 2267, from the slopes of Konahuanui, back of Honolulu, 

 has elliptical-lanceolate leaves, acute at both ends. The flow- 

 ering panicles are erect. On Kauai it is common in damp 

 woods on the lee side of the island up to an elevation of 4000 

 feet. Here it is larger in every way than on Oahu, and is not 

 typical. The tree is larger, the leaves are broader and some- 

 what longer, but preserve the same general shape that they 

 have in the Oahu plant. Petioles two or three times longer 

 than in S. kaduana, is also a constant character in this species. 

 As the types of both species came from Oahu, it is only there 

 that we may expect to find anything like the originals, and 

 specimens from other islands can merely be referred to one or 

 the other with more or less uncertainty, especially since it is a 

 recognized fact that outside of the introduced species, there 

 are very few species common to two or more of the islands.

Straussia psychotrioides n. sp. (Plate LXII.) 



A small tree, ten to fifteen feet high, branching above, the 

 branches loose and spreading, with the young parts more or 

 less angled; bark gray, somewhat ridged; leaves opposite, usu- 

 ally divaricate, or sometimes reflexed, obovate oblong, the
