count, with descriptions of critical species, of his discoveries since the 
date of the last edition of the ‘ Flore du Centre,’ is based. We will 
select from it a few of the critical notes which are most likely to in- 
terest our readers. 
is Barbarea stricta is evidently the same plant as ours, and he 
says that whilst he has seen B. vulgaris in the department in two loca- 
lities only, both of which are in the vicinity of habitations, B. stricta is 
plentiful in woods and damp places. 
Capsella rubella of Reuter (C. rubescens, Personnat) he describes as 
ollows :—Leaves dark-green, the lower ones and the root-leaves lyrate- 
pinnatifid, the upper ones entire and narrowly sagittate at the base ; 
sepals glabrous, oblong, reddish at the apex, surrounded by a narrow 
membranous border; petals scarcely longer than the calyx, equalling 
the stamens; silicles equalling the pedicels, emarginate at the apex, 
shortly apiculate by the style; seeds small, brown, five or six in each 
cell. It has been gathered in Switzerland, Savoy, and numerous 
stations in the southern half of France. e have seen authenticated 
specimens both from Switzerland and France, but in these the pedicels 
are longer than the silicles, and the only notable difference which we 
can detect between this and our common C. Bursa-pastoris, is in the 
sepals, which are conspicuously pellucid all round the edges, and the 
central portion bright red in hue, and in the larger and longer petals 
of this latter. Upon looking over our British specimens of C. Bursa- 
pastoris, we find an example with petals almost double the length of 
the sepals, but these latter have a decidedly reddish tinge and a slightly 
membranous border, so that we cannot aceept C. rubella as more than a 
variety. 
Viola Biturigensis of Boreau is an interesting discovery. It is nearest 
to 7. stagnina, and has a similar habit of growth, but the flower is 
much larger; the spur of the corolla more than half as long again as the 
calycine appendages, and the leaves are oval-acuminate or lanceolate 
instead of subcordate. 
Under Arenaria serpyllifolia, M. Martrin-Donos (‘ Notes sur la Flore 
du Tarn’) distinguishes three plants as follows, exclusive of L/oydii. 
1. A. leptoclados, Guss., easily distinguished by the tenuity of all its 
parts, and its slender oval-elongated capsule, which yields to pressure 
without bursting. 2. 4. serpyllifolia, L., with slightly spreading 
panicle, erect fruit-pedicels, sepals shorter than the oval subglobose
