FLORA OF OXFORDSHIRE. 391 
referred to Pyrola rotundifolia is correctly identified by Sibthorp with 
P. minor. Blackstone’s Salia pentandra is also absent. Ray’s Salix 
acuminata is here wrongly referred to cinerea; Herminium Monorchis, 
although recently found by Dr. Lightfoot, is omitted, and no notice is 
taken of Plot’s variety of Epipactis latifolia. The Asplenium from Adder- 
bury (either erroneously described as lanceolatum by Bobart, or an alien 
there) is not given. 
About 530 species are additions to the county Flora, which with varieties 
and plants previously recorded was now shown to contain about 780 
species and varieties. 
In this Flora, Sibthorp first describes as British plants Ranunculus 
eireinatus, R. fluitans, R. heterophyllus, Erodium cherophyllum, Arabis 
Turrita. He also described under names which are still retained Juncus 
glaucus, Lychnis vespertina, L. diurna, Potentilla procumbens, Trifolium 
dubium. 
In addition to the Phanerogams, 87 species of Musci are described, as 
well as 20 species of Hepatice, and over 340 Lichenes, Alge, and Fungi. 
In the Preface Dr. Sibthorp mentions the chief rarities of the county, 
pointing out the Monotropa, Pyrola, Cephalanthera of the chalk woods, 
the Lycopodium and Oreopteris on Shotover, and the Pinguicula and 
Parnassia on Bullingdon Green. He alludes to the Orchids on the chalk 
downs and to the presence there of Onobrychis and Iberis, with the 
parasitic Orobanche. The Burford Downs are stated to yield Ophrys, 
Senecio campestris, Anemone Pulsatilla, and Astragalus danicus; while 
the rivers about Oxford have both water-lilies, the arrowhead and flower- 
ing rush. As plants not indigenous mention is made of Hieracium ce- 
rinthoides (probably H. amplexicaule), Senecio species (S. squalidus), and 
Tinaria Cymbalaria. 
Such a work as this, so accurate and thorough, the result of personal 
toil and observation, placed Oxfordshire for a long time at the head of 
counties with published floras. The best proof of its excellence will be 
seen, when the additions made during the next fifty years are noticed. 
Sibthorp had a country house near South Leigh, which will explain the 
frequent references to that portion of the county. His descendants have 
been munificent donors to the church there. It must be borne in mind, 
that since his time, field enclosure has taken place, most of the commons 
have become absorbed, and the great limestone tract of the west brought 
under cultivation. Hence many of the plants he mentions have become 
rare and some extinct. Of his herbarium of British plants I am unable 
to find a trace, and whether it went in the ‘heap of waste paper’ to the 
local paper-mills or whether its fate was to perish at the hands of some 
energetic ‘ cleaner out,’ is an open question. Some portion evidently 
remained to comparatively recent times, for Mr. Newbould was shown 
a small bundle by Mr. William Baxter, in whose careful hands it was 
not likely to suffer. There may be a few of the Sedges in Dr. Goodenough’s
