A Burtnannia, 15 species of Utricularia, and 10 species of 

 JEriocaulon, with 5 species of Loheliacece, 1 species Serpicula, 1 

 Rumex ! 2 species Epilobium, and a Richardia spatha sulphurea, 

 grow in the bogs. 



Salix, Rubus, JEricacece, 5 species Droseracecs, 2 species Prvrnu- 

 lace<B, 2 species Trifolium, and 5 TJmbelliferce adorn the banks of 

 streams. 



A gigantic Limosella, a Limnophila, with the habit of a Cerato- 

 phyllum, a Cyphia, together with Lythrum, Isnardia, Potamogeton 

 (3 species), 2 species Ottelia, and several other Vallisneriaceee, 

 hitherto only known from India, cover the stagnant waters. 



Numerous species of Gladiolus, 22 species of Orchidia?, 30 

 species of Filices, and many very pretty Scropliulariacea, deck 

 the damp slopes of the mountains with their many-coloured 

 flowers. 



Three species of Selaginece, together with many small Leguminosce, 

 Composite, Cyperacece, and Graminece, constitute the vegetation of 

 the pasture lands. 



One Osyris, 3 species Thesium, and 5 Daphnoidece (the latter of 

 the most brilliant colour) adorn the dumeta, which are principally 

 made up of Duranta, Cyclonema, and several species of Stroph- 

 antus. 



Of the ten Protectees, 4 or 5 of the species belong to an entirely 

 new genus, which, with the character of a Protect, unites flores lon- 

 gissime spicatos and the habit of a Salix. 



"What, however, will most interest you, were 10 species of 

 Gentianece and one Rafflesiacea, with the habit of Apodanthes, 

 of which I had the fortune to find male and female flowers. This 

 Rafflesiacea grows upon the branches of a Legwninosa casalpiniacea. 

 I shall have the honour of sending you entire specimens of both male 

 and female preserved in spirits. My collections to the south of the 

 river Cuanza amount to about 2500 species. I hope to commu- 

 nicate to you specimens of all the interesting ones.

On a New British Plant. By Joshua Clabke, Esq., F.L.S. 



[Read Nov. 1st, I860.] 



I wish to present to the Society specimens of a new British plant, 



Lathyrus tuberosum (Tuberous-rooted Vetch). It was collected at 



F) field, near Ongar, Esses, last August. It is a beautiful bright
