NOTES ON ABBOT’S HERBARIUM, 41 
number of the specimens, many of which are mere tops and scraps 
quite impossible to determine, and the complete absence* of an 
indications as to the localities in which they were gathered, their 
value is very much diminished for critical purposes. 
us it cannot be certain that any one specimen was collected 
within the limits of the county which the herbarium professes to 
e names first given are taken from the sheets of the her- 
barium, and notice has been taken of any discrepancy between 
them and those employed in the Flora. It has been thought 
unnecessary to mark the absence of the very common and 
universally known species. 
Callitriche verna. The specimen is a mere scrap, but with ripe 
fruit; this has the erect styles and bluntly rounded edges of C. 
obtusangula, Le Gall. The figure quoted has been usually taken to 
Tepresent C. platycarpa, Kuetz. It would be desirable for some 
resident botanist to search the ditches in the neighbourhood of 
Ford End. aint 
C. autumnalis. Without fruit, and too young for determination, 
but looking more like C. vernalis, Kuetz., than C. hamulata, Kuetz.

Valeriana officinalis. The true upland plant, V. Mikanii of 
Syme. Is not this V. procurrens, Wallr. ? , ; : 
- Locusta, Valerianella dentata, Poll., the variety with hairy 
fruit, 3. lasiocarpa of Koch. 
Agrostis capillaris. A. vulgaris, With. 
Poa angustifolia. P. nemoralis, L. : 
- nemoralis, The specimen is not altogether determinable, 
but is suggestive rather of the larger forms of P. compressa 
flexa. P. distans of Flora; Glyceria distans, Whinb. 
Festuca rubra and F’. duriuscula. Indeterminable. 
F’. ovina. Does not well represent the typical plant, as figured

F. fluitans. Exactly Glyceria pedicillata of Townsend, as might 
_ have been inferred tg the ramliaane to the “‘ admirable figure’ 
of Curtis. The plate quoted from the ‘ Flora Rustica’ apparently 
Tepresents the same thing. In the last edition of the ‘ Manual, 
Professor Babington has removed G. pedicillata as a variety from 
- plicata, Fr., and placed it under G. Jiuitans, Br., and in this 
may perhaps have been influenced by Fries’ reference to Curtis
