PLANT NOTES FOR 1913, ETC.

variifolia (DC), and auriculata (Beck), nor to the hybrid with 

 sylvestris (R. barbarioides Tausch). Under R. Nasturtium-aquaticum 

 he considers the var. siifolia (Reichb.) and the sub-var. microphylla 

 (Reichb.) as states. Arabis Thaliana appears under the unfamiliar 

 name Arabidopsis Thaliana (Schur). Brassica monensis is used as 

 representing B. Cheiranthus Yill. Surely there is a difference 

 between the plant of our western coast and the Channel Island 

 species. Sinapis is once again a separate genus, and Brassica incana 

 is Hirschfeldia incana Moench. Under Cardamine hirsuta he has 

 sub-sp. C. sylvatica, but wrongly attributed to Rouy & Foucaud 

 instead of Syme. Jt might have been expected that such an active 

 nomenclaturist as M. Briquet would have found it necessary to 

 consult the third edition of English Botany, Syme being a pioneer in 

 the making of sub-species. Rapistrum rugosum has 3 sub-species 

 under it, including Linneanum and orientate. R. hispanicum Crantz. 

 Crucif., however, dates from 1769, and the Myagrum hispanicum 

 L. Sp. PL, 1753, has the older trivial, Linneanum only dating from 

 1842. M. Briquet says Thellung in writing R. rugosum sub-sp. 

 hispanicum is contravening the Actes. See Art. 49. When one 

 considers the purely arbitrary distinction between species and sub- 

 species one can see how little permanence or uniformity of nomen- 

 clature can be obtained by this rule. Surely the permanence under 

 the older trivial appeals to common sense. Briquet rejects Garsault's 

 names because that author employed " uni-bi-pluri " nominals. They 

 are now given in the Suppl. Index Kewensis. Vogelia is correctly 

 used instead of Neslia, our alien species being V. paniculata Hornem. 

 Crataegus Pyracantha Med. becomes Pyracantha coccinea Roem. 

 Three species only of Rubi, one numbered hybrid albidus, one sub- 

 species rusticanus (Syme had already named it sub-species discolor), 

 and a variety only are given, a ' masterly ' treatment of a difficult and 

 fluid genus which, however, in Corsica is much less varied than in 

 Britain. Nine species of Rosa are described. Pyrus Malus var. 

 mitis Wallroth is said to be = P. Malus var. paradisiaca L. 

 Laburnum vulgare, 1843, is used instead of the older L. anagyroides 

 Med. M. Briquet does not state by what article of the Actes he 

 disposes of the older name. Medicago hispida Gaertn. is used as in 

 the List with its vars. apiculata, lappacea, and denticulata. Our 

 Trigonella Melilotus-ornithopodioides is once again put under Trifolium 

 as in English Botany. Medicago minima Grufb. and Trifolium
