ARTICLES IN JOURNALS. 357 



While frequently agreeing with the writer in the changes he 

 proposes, there are one or two points as to which we are inclined 

 to differ from Prof. Niedenzu, or which seem to call for further 

 explanation. For example, Bitnchosia mollis is described by Bentham 

 (in Hooker's London Journal of Botany, vii. 127), and founded on 

 Schomburgk's no. 742. It is represented by this number of Schom- 

 burgk's in the National Herbarium, and seems indubitably Mr. 

 Bentham's plant ; but Dr. Niedenzu quotes Schomburgk's no. 742 

 for the preceding species, Bunchosio rhombifolia Turcz., and for 

 B. mollis Benth. he quotes no. 544. Further work seems de- 

 sirable on some of the plants of this genus found in New Granada. 

 Prof. Niedenzu places B. retusa Tr. & PI. among his unknown 

 species, and altogether omits B. deflexa Tr. & PL ; but specimens 

 of both exist in the National Herbarium, and the latter, as well as 

 the former, was published in 1862 (Ann. Sci. Nat. ser. 4, xviii. 

 311). We are not clear where the monographer intends to place 

 the New Granadan plants which Triana & Planchon (/. c.) refer to 

 B. nitida. It ought not to be difficult to obtain information regarding 

 the three *' incognitse " described by Sereno Watson in the Proceedings 

 of the American Academy within the last three years. B. cumanensis 

 Don stands in a different category ; the name appeared in Loudon's 

 Hort. Brit. ed. 2, p. 170, but no adequate description is given, and 

 it is probable no type exists.
