As with the preceding portions, so too these parts of the 

 Flora teem with interesting points, and are invaluable to the botanical 

 student. We can only here express our gratitude to the great botanist 

 Prof. Ascherson, who has done such excellent floristic work, and offer 

 our sincerest sympathy to his surviving colleague, with the sincere 

 hope that he may be spared to bring to completion such a monumental 

 undertaking.

 10 francs. This, the completing volume of the valuable and suggestive 

 French Flora, crowns the prolonged labours, and demands the hearty 

 gratitude of all systematists to its veteran author. This volume 

 contains the Graminees and Vascular Cryptogams. Spartina Neyrauti 

 Fouc. represents S. Townsendi in France, and is said to be a hybrid 

 of the same species. Agrostis vulgaris is made a sub-species of A. 

 alba, as is A. maritima, and A. prorepens Rouy ; but A. tenuis Sibth. 

 is an earlier name for A. vulgaris. Air a multiculmis Dum. is made a 

 sub-sp. of A. caryophyllea. The name Deschampsia discolor is used 

 instead of D. setacea, which retains the earlier trivial. The nomen- 

 clature, however, in this, as in the preceding volumes, is decidedly 

 erratic. Avena sterilis L. is rejected because the plant is not sterile. 

 Trisetum pratense is used instead of T. Jlavescens, Glyceria spectabilis 

 instead of G. aquatica. Koeleria and Sesleria become Koelera and 

 Seslera because they are named after Koeler and Sesler. Desmazeria 

 of 1823 is replaced by Catapodium of 1827. Under Avena sativa are 

 grouped A. orientalis, A. nuda, A. strigosa and A. brevis. Glyceria 

 jluitans has a var. triticea Fries (Festuca loliacea Huds.), and the 

 sub-species plicata has a var. depauperata Crepin, said to be synony- 

 mous with the var. triticea M. T. Lange. A large variety of Glyceria 

 Borreri (3-5 dc.) is var. erecta Corb. Fl. Norm. 653 which is put by 

 M. Rouy under Atropis. Glyceria distans var. tenuiflora Gren. & 

 Godr. becomes var. miliacea (Rouy, p. 196, under Atropis). It is the
