A Correction. — In August I recorded Hieracium ^^melano- 

 cephalum'' for Argyle. Mr. Hanbury and myself, on visiting the 

 locality this summer, could not find that plant, but H. gracilentum 

 in plenty. The two are much alike in a dried state, but a fresh 

 examination of last year's specimens leads us to refer them to graci- 

 lentum. The original record must therefore be cancelled. — Edward S. 

 Marshall. 



Erica vagans near Bournemouth. — In the ' Flora of Hamp- 

 shire,' Mr. Townsend speaks of this heath having been found in 

 two spots near Bournemouth, but beyond the Hants border. It 

 may be well, therefore, to put on record the fact that it now grows 

 in Hants, on the moor near Bournemouth, at a distance of about 

 two miles from the localities described by Mr. Townsend. Having 

 been directed to this place a few weeks ago, I found three clumps 

 of the plant, each covering about a square yard of ground, and one 

 of them at a distance of some twenty yards fi'om the other two. 

 They looked as truly native as the other common heaths growing 

 around, and if originally planted there (as seems most likely), they 

 evidently do not dislike the home provided for them, as they are 

 flowering freely and obviously spreading. I have not heard of the 

 recent occurrence of this species in Dorset, and so far have looked 

 for it there in vain. But it is so abundantly planted in Bourne- 

 mouth gardens, that it may well occur in more places than one in 

 the heathy districts near, without any intentional interference with 

 nature on man's part. — W. Moyle Rogers. 



NOTICES OF BOOKS. 

 Monographia Fhanerogamurum ; edit. Alph. et Cas. DeCandolle. 

 Vol. VI. — Andropogone^. By Edouard Hackel. 8vo, 

 pp. 716 ; 2 plates. Paris, G. Masson. April, 1889. 



Prof. Hackel has undertaken the grasses for the DeCandolle 

 • Monographiae ' ; the present volume contains the first tribe, the 

 AndropogonecB, i.e., 425 species oat of 4000. It is an admirable 

 performance, it involves the resolution of very numerous difficulties, 

 and the way in which some of these are resolved may be discussed 

 here without any intention to assert that the author has sometimes 

 chosen the more objectionable of two dilemmas. 



Hackel accepts the limits of the tribe Andropogonem exactly as 

 fixed by Bentham in the ' Genera Plantarum' (one species, Cleistachie, 

 being added) ; and he accepts very nearly the genera as defined by 

 Bentham, the principal difference being that Sorghum, Chrysopogon,
