LXX. An Account of Aphyllon and Dentaria 
heptaphyllos of Clufius, omitted by M r. 
Ray : by Mr . William Watfon, F. R. S. 
Read April 1 6, nr R t Watfon prefen ted to the Society 
JL fome fpecimens of two plants, now 
in flower, which he faid were not frequently found 
in England. One of them was the Anblatum of 
Cordus, or Aphyllon of John Bauhin. This plant is 
denominated Squamaria by Rivinus, and Dentaria cro- 
codylia by Tabernamontanus. Linnaeus, in the Flora 
Suecica , calls it Lathraa caule (implicijjimo , cor dlls 
nutantihus , la bio infer i ore trifido. Mr. Ray, in his 
Synopfis plantarum Anglia, takes notice of its being 
found near Darking in Surrey, but the plant now r 
prefented was collected near Harefield in Middlefex. 
The other plant offered was the Dentaria kept a - 
phyllos baccifera of Cafpar Bauhin, or Dentaria tertia 
baccijera ol Cluflus. This plant is treated of by 
Linnasus, in the Hortus Lliffortianus , and by Van 
Royen, in the Flora Leydenfis prodromus, under the 
appellation of Dentaria foliis infer ioribus palmatis , 
j'ummis Jimp lie ibus.
