290 Mr. C. C. Babington on A. Porrum and A. Ampeloprasum, 



stamen, and the anther-bearing point is only half the length 

 of either the common filament or of the barren points ; but 

 in the latter the segments of the perigone are longer than 

 the common filament, to which the anther-bearing point is 

 equal, but at the same time only one-third of the length of 

 the barren points. 



In Gaudin's Fl. Helv. v. ii. t. 11. the perigone of ^. Ampe- 

 loprasum is figured as longer than the stamens, and thus not 

 at all agreeing with our plant, which more resembles his figure 

 of ^. rotundum, t. 10, in which he represents (and at p. 482 

 describes) the stamens as longer than the perigone, differing 

 in this from all other writers who have described A. rotun- 

 dum, quoting Clusius, Hist. v. i. p. 196. (for 190.) for A. ro- 

 tundum instead oi A. Ampeloprasum, to which it is usually, and, 

 as it appears to me, correctly referred, and omitting A. Ampe- 

 loprasum, Wald. and Kit. t. 82. which is generally considered 

 as a good figure of A, roiundum. He has not given a repre- 

 sentation of the root of ^. rotundum, but those of ^4. Porrum 

 and Ampeloprasum are pretty characteristic. I am not satisfied 

 with his figures of the fruit. 



1. A. Porrum. 2. A, Ampeloprasum. 



It is remarkable that all the writers to whom I have referred 

 describe the heads of both these species as bearing cap- 

 sules and not bulbs ; for I find that some individuals of the 

 former produce bulbs on the head, amongst the flowers, in 

 cultivation, and that the same is the case with the latter in a 

 wild state in Guernsey. 



I propose the following specific characters for these plants, 

 both of which are distinguished from ^. rotundum by their 

 exserted stamens. 



1. A. Porrum (Linn.). Caule ad medium folioso, foliis planis.
