FLORA OF OXFORDSHIRE. 383 
lamprocarpos in the adjacent meadows. In Shropshire Dr. Littleton 
Brown joined them. Along the Severn they noticed Brassica sylvestris, 
and Sinapis nigra and the cut-leaved form of Heracleum. From Dolgelley 
they ascended Cader Idris ‘and found a great many of the Welsh plants 
there.’ These included Epilobiwm alpinum—Chamenerium alpinum minus 
prunella foliis prope Dollgelley ubi ascendit Cader Idris primum, dein in 
Glydyr reper. This has not since been recorded from Wales, but speci- 
mens are in the Dillenian herbarium. They found too the Alpine form 
of Campanala rotundifolia and many mosses and lichens. Between 
Carnarvon and ‘Dolgelle’ they gathered Vicia Orobus, which is still 
preserved in his herbarium. Littorella was found in the river near 
Lianberis, and also Isoetes. Anglesea was next visited, but Dillenius did 
not speak highly of its richness in rare plants. They gathered Mertensia 
maritima, Asplenium marinum and Gentiana Pneumonanthe. In ‘2 small 
river that runs out of 4 pond near Esquire Baly’s’ Dillenius found 
Potamogeton foliis oblongis, planis, inferné alternis, superné constipatis. 
This plant is preserved in his herbarium and proves to be Potamogeton 
nitens, the Dillenian specimen having been found more than « century 
before it was described as a British plant. 
Near Newborough in Anglesea they gathered Thalictrum maritimum, 
Ononis repens (Ononis maritima procumbens), and V ulneraria flore coccineo, 
now known as dAnthyllis Dillenii. Euphorbia Portlandica and Viola 
Curtistt were also found. Cakile maritima and Brassica monensis were 
discovered at Abermeney Ferry. They then went to Snowdon, finding at 
its base Wahlenbergia and in the lake at the foot of Gribgech Potamo- 
geton, lapathi minoris foliis pellucidis, suggested by Dawson Turner to 
be heterophyllus; it is, however, a form of P. polygonifolius. They 
missed the Woodsia, and Lloydia. In Llyn y Cwm Subularia was 
gathered, and on the hill Lycopodiwm annotinum. 
Other plants gathered in Wales on this tour were Juniperus nanus, 
Alsine verna, Alisma ranunculoides, var. subrepens, Salix herbacea, 
Carex pallescens, Hypericum quadrangulum, Anagallis tenella, Nitella 
opaca, etc. In 1732 Dillenius published the Hortus Hlthamensis in two 
folio volumes with 324 plates, drawn and engraved by himself (as were 
those in his other books), and descriptions of about 400 rare plants, which 
were cultivated in Dr. James Sherard’s garden at Eltham. This work 
did not sell, and a portion of it was cut up to hold his Hortus siccus. He 
appears to have disliked preparing it, as he considered it was only done to 
bring James Sherard into notice. Dillenius says that James Sherard 
made ‘him lose more than £200 over its publication, besides much 
valuable time,’ and complains that after Consul Sherard’s death ‘he took 
me off and set me to work in his garden, to make himself known, and 
promised to do great things, viz. to pay for the plates, paper, etc., but 
when it came to the performance he did nothing; and, not to lose so 
many years’ labour, I undertook it at my own expense. All his kindness
