our F. palustris. The flowers, too, have the most perfect agreement with the preceding- species, bcingf small, 

 white, or nearly so, Avitli the lower petal, and sometimes the two lateral mostly beardless ones, streaked 

 with purple; indeed Professor Bigelow, who has very accurately studied, and very faithfully described, the 

 plants of the neighbourhood of Boston, has found so many intermediate forms of leaf between this and V.lan- 

 ceolatOj that he is of opinion they are in all probability one and the same. 



9. F. clandestina ; stigmate marginato, foliis teneris glabris orbiculari-seu reniformi- 

 cordatis obtusissimis crenato-aerratis sinu profundo, petalis aiiguste ovatis imberbibus, 

 floribus saepe apetalis. — Pnrsh, FL Am, v. 1. p, 173. Schwein, Viol in Sill. Journ, i\ 5. p,

Hab, About Lake Bourbon and Lake Wiuipeg. Dr. Richardson. — This was named V. clandestina by 

 Dr. Richai'dson on examining it when recently gathered, and it does seem suffit-iently to correspond with 

 the character of Pursh, who is the original authority for it, in everything, except that I do not find the 

 " stoloues to be floriferous." Le Conte says that the " peduncles are subtetragouul, branched, with 2-8 

 flowers, and a pair of stipules beneath each pedicel." In some of our specimcus the flowers are apetalous, 

 and the peduncle bent down to meet the earth; in others, there are perfect flowers, in every respect, as far 

 as can be judged from dried specimens, agreeing with those of V. hlanda, Witli that species, indeed, Pro- 

 fessor Torrey is disposed to unite it, and I see myself no difference but in the much larger size of the leaf 

 and the trilling character above-mentioned. Pursh has, doubtfully, referred V. rotundifolia of Michaux to 

 it; and De CandoUe has considered V. clandestina identical with rotundifolia: but in this, all the American 

 Botanists differ from him.

Hab. Canada. Torrey ; Le Conte. — The flowers are described as yellow; which I cannot judge of from 

 the dried plant; nor do 1 possess specimens, save from Mr. Schweinitz, Dr. Torrey, and Dr. Boott, gathered 

 in the United States. In all these the leaves are large, almost exactly ovato-cordate, with a narrow sinus. 

 Dr. Boott's specimens have imperfect flowei-s, which appear to bury themselves in the earth, and very thin 

 semipellucid membranaceous leaves : those in flower, from Dr. Torrey especially, have the foliage coriaceous.
