1 These papillse the Rev. Professor Henslow has clearly ascertained to be 

 little bulbous (/einintB, and as such has described and fiijured them in the Mng. 

 of Nat. Hist. V. i. p. 442; a fact suspected previously, in 1824, by Mr W. 

 Wilson, who further finds an hybernaculum formed in the autumn among the 

 decayed leaves. Thus, independent of seeds, this curious little plant has one 

 mode of perpetuating itself, and another of increase.
