2S MERRILL. 



mm in diameter, the peduncles slender, about 1 cm long. Flowers 

 yellow, with a faint odor, the calyx 2 mm long. Pods 4 to 9 cm long. 

 7 to 10 mm wide, dark-colored when dry, shining, base acute or acu- 

 minate, the apex acute or somewhat curved-apiculate, somewhat inflated 

 opposite the seeds and frequently constricted between tliem, scarcely 

 reticulated. Seeds 4 to 8 in each pod, elliptic, compressed, 5 mm long, 

 their longer diameter arranged parallel with the pod, not at riglit 

 angles to it. 



Luzon, Province of Zainbales, Merrill 211.'f (type), For. Bur. 5922, 1010 Curran. 

 Formosa, Henry 77.^. 



Acacia richii is said to be represented also by the following Formosan speci- 

 mens, which I have not seen: Oldham 193, Swinhoe s. n., Ford s. n., fide Forbes 

 & Hemsley; Faurie '/I, 1^/1, fide Matsuraina and Hayata. 



After a careful examination of the Philippine material, and a specimen of 

 Henry 77-J from Formosa, and comparison of this material with the original 

 description and figure, as well as with a typical phylloclade from the type collection 

 of Acacia richii A. Gray, I am convinced that the form above described as Acacia 

 confufsa is specifically distinct from Gray's si>ecies. About four years ago Dr. t". 

 B. Robinson, then at the New York Botanical Garden, called my attention to the 

 (HfTerences between the Philippine material and the type collection of .1. richii, 

 and kindly supplied me witli a fragment of the latter, expressing the opinion that 

 two species were represented, an opinion in which I entirely concur.
