Engler describes two of the hele as each having a pair 
glands on the back, but I find a single large gland on the calyx, 
just as in d. longifolius, or, less frequently, two large glands. 
By the exclusion of four species from the genus and the 
reduction of three others, the number of recognized species is now 
reduced to twenty, to which have to 22 added three new ones 
described in the present paper. AsI have seen specimens of only 
six out of the twenty-three, & monograph a of the 
enbject is out of the question, bets w remarks on the generic 
characters and the inter- ladidehine. fr the Sosias may be of 
assistance to future workers.

Hooker and Niedenzu describe one carpel as being always abortive, 
but all thr three may be developed, as occurs in A. excelsus and 
i terus var. Cavanillesii, for example. Niedenzu describes 
the bracteoles of Acridocarpus as being very small, which is h 
the case in A. plagiopterus and its allies. The descriptions of 
Acridocarpus in the Genera Plantarum and Pflanzenfamilien call for 
no further remark. 
Among the best specific characters are those afforded by the 
bracts and bracteoles, the glands on the calyx, and the shape and 
retienlation of the leaves. ‘The flowers are very bape wii nese
