SHORT NOTES. 63 



may be var. integrata G. & G. The form hipinnatijida of Wirtgen, 

 with bipinnatifid leaves from the first, is common and easily dis- 

 tinguished, especially when the plants are young. Two forms occur 

 with the rachis broad : (1) smooth fleshy plants corresponding to 

 var. mantima G. & G. ; (2) those having ascending hairy leaves 

 with broader pinnae (thus appearing to be coarsely serrate) — perhaps 

 var. latifolia DO. A plant corresponding to var. pygmaa Lange is 

 plentiful on the Bude Downs and at Braunton Burrows. With the 

 exception of var. integrata G. & G., these forms are easily recognized. 

 Two very distinct forms of P. ynaritima L. occur at Bude : (1) a 

 large plant with simple root, and flat, linear-lanceolate leaves ; 

 (2) one with many tufts of curved linear leaves at the ends of a 

 branched rootstock, forming together a small compact cushion. 

 But for their obtuse bracts they correspond respectively to speci- 

 mens of P. serpentina Vill. and P. carinata Schrad., from the 

 Mediterranean. A form of P. lanceolata L. with spreading teeth to 

 its leaves, known on the Continent, but not hitherto, I believe, in 

 England, occurs at the same place. — S. T. Dunn.

 — The form from Braunton Burrows (M. hirsuta Huds.) has a very 

 distinct appearance in consequence of its procumbent habit, the 

 whole plant being tightly pressed upon the sand, and the leaves all 

 in one plane. That it is merely a variation due to environment is 

 suggested by its gradually passing into the typical form where there 

 happens to be a tuft of rushes or other shelter. — S. T. Dunn.
