Looking at these numbers again, we find that 472 may be called ubiquitous or 
common; 163 rare or local; of which 163, the remarkable number of 14 are unique 
as regards Herefordshire, not occurring elsewhere in the county. The unique 14 
are the following— 
Hutchinsia petra, Br. Hieracium pallidum, fF’, 
Cerastium tetrandrum, Cuw/'t. 5 lasiophyllum, Koch. 
Hippocrepis Comosa, LZ. ss cesium, Fr. 
Epilobium brachycarpum, Leight. Epipactis ovalis, Bab. 
Sambucus laciniata. Carex humilis, Leysse. 
Rubia peregrina, LZ. > montana, LZ. 
Gnaphalium dioicum, Z. Melica nutans, D. 
Of the other rarities, the following seem to deserve especial notice— 
Helleborus fcetidus, Z. Sedum Telephium, ZL. 
Helleborus viridis, LZ. Epipactis media Fr. 
Cerastium semidecandrum, Z. Blysmus compresssus Panz. 
Tilia grandifolia, Ehrh. Carex digitata, D. 
Rubus plicatus, W. & WV. Keehleria cristata, Pers. 
Cephalanthera grandiflora, Bab. Hordeum sylvaticum, Huds. 
5 ensifolia, Rich. Polypodium Robertianum, Hoffm. 
And the introduced— 
Atropa Belladonna, Z. Poterium murieatum. Spach. 
Plantago Coronopus, L. Aster, Sp. (R.) 
Selecting from these, we may notice Hutchinsia petra as an interesting station, 
forming a single stepping-stone between its scattered southern stations at Bristol 
and in South Wales, and its more northern home in Derbyshire. It seems to have 
decreased in quantity at the Dowards of late years; and the same remark has 
been made to me by the Rey. W. H. Purchas with regard to this plant in Derby- 
shire. 
The two small Cerastiums, tetrandrum and semidecandrum are surprisingly 
rare in Herefordshire ; the former resting upon a single specimen alone, gathered 
at the Doward Quarries many years ago by Mr. Purchas; and the latter being 
found only very sparingly at one or two spots, at long intervals both of distance 
and of time. 
Tilia grandifolia has much interest ; the limestone cliffs of the Wye valley 
being regarded as nearly the only locality in Britain where it is certainly wild. 
But its nativity is one of the knotty points ; and it certainly occurs in other places 
in Herefordshire with quite the aspect and surroundings of a wild plant. 
The Hieracia are decidedly a feature of the Doward rarities ; the three, palli- 
dum, cesiwm, and lasiophyllum, being confined to this station in the county, one 
of them, lasiophyllwm, being also rare throughout the whole of England. Judicious 
botanists, who know the difficulties of this genus, may perhaps pause before ac- 
cepting these plants ; this alone I feel, that these names represent something more 
than mere names for one and the same plants ; what more, I cannot say. 
The Orchids are, as might have been presumed, largely represented ; the two 
species of Ophrys, apifera and muscifera, being both rare in our county. O. mus-
