separate alphabetical arrangement under Icica and Elaphrmm. 

 In Cappari* a further variation in enumeration occurs, " 10. 0. 

 frondosa, Jacq. ," being followed by "11. C.frondosa? " and " 13. C. 

 loinrinskiana, Schl.," by " 14. C. karwiiiskiana, Schl., proxima 

 sed sepala longiora." We do not see why these doubtful plants 

 should receive a separate number ; and we may here take exception 

 to Mr. Hemsley's uniform practice (following that of zoologists) 

 in spelling such names as Karwinskiana with a small initial. 

 Warpers' reference to'Linnsea,' under Pol ygala cahipes, is stated by 

 Mr. Hemsley to be incorrect ; but this is not the case, the 

 inaccuracy being in Mr. Hemsley's citation from Walpers ; and we 

 miss P. tenella, Willd. (a Panama species), from the list. 



Another matter which seems to us unfortunate is the omission 

 of the Central American plants contained in the British Museum. 

 It seems to be supposed, by those unacquainted with the actual 

 state of the case, that the British Museum herbarium is mainly a 

 duplicate of that at Kew, and it is consequently more or less over- 

 looked by some who are engaged on monographs or local floras. 

 Mr. Hemsley may have had other reasons for neglecting to consult 

 the British Museum collections, but it is none the less a matter of 

 regret that he has not done so. That he could hardly have failed 

 to estimate the importance of that herbarium is evidenced in his 

 enumeration of the species of Clematis, the only genus for which 

 it was referred to. Of the 16 named species which Mr. 

 Hemsley enumerates, 2 have been seen by him only in this 

 collection— one, C. americana, Mill., from Campeche (Houston and 

 bhakespear) ; the other, C. flammulastrum, Griseb., from Yucatan 

 (A. Schott). In this genus it may be noted we have a plant [C. 

 (jrahawi, Benth.) retained and numbered as distinct, although Mr. 

 Hemsley quotes from a note of the founder of the species, " a C. 

 cm-ipensi non nisi foliis pubescentibus differt." Had the plants 

 contained in the Kew herbarium been the only ones quoted, the 

 neglect of the British Museum collections would have been less 

 noticeab e, but Mr. Hemsley not unfrequently quotes Hb. Paris for 

 plants which he might more readily have seen in London. 



Among the collections in the British Museum herbarium, which 

 should have been included in Mr. Hemsley's enumeration, may be 



p ; V; "eruariuin oi liuiz and Pavon, a set of Cuming s 



lanama plants, and a series of Berlandier's Mexican plants, which
