H. exannulatum is quite as frequent as ZZ. fluitans, the presence 
_of pools and channels seeming to be more necessary for the latter “4

than for the former. 
HE. HI. LYCOPODIOIDES and H. WiLsonr. 
On Skipwith Common are many square yards of very fine 
H. lycopodioides, and along the side of this is also very fine 
H. Wilsoni not in such a wet place as the former. There is the 
_Strongest evidence that Z. Wilsuni is a derivative of the /1. lyco- 
 podioides. On 1 Aug. 1900 I found masses of the latter with very

slender shoots, resembling stems of H. Wilsoni. and on 18 Apr. 
1906 in quite a different habitat a few miles away and between 
heather and a ditch by the road-side, 1 found both species 
intermixed, but the Æ. {ycopodioides was the dominant partner. 
To my mind #. Sendineri forma vulgaris has quite a different 
origin from all other forms of 4. Sendineri and from H. Wilsoni.
