536 • Mr. Forster's Observations on the 



underside, and sometimes on the upper surface ; and in Clifford's Herbarium 

 in the same valuable collection, there is a similar specimen, marked also 

 E. palustris. The E. pilosa of the Banksian Herbarium is a totally different 

 plant, which is accounted for by Dryander in a MS. note in the Species 

 Plantarum : " Plaiita Sibirica Linn. Herb, exacte refert figuram Gmelini, 

 distincta a planta Europse Anstralis." My specimens from Bath differ in no 

 respect that I can discover from the Banksian specimens, or from the Siberian 

 one preserved by Linnaeus under the name of E. pilosa, yet differing from his 

 description of that plant in the manifest hairs, as well as in the serratures, 

 which are frequently very visible, except towards the base ; sometimes, indeed, 

 they are inconspicuous from the doubling of the edge of the leaf, but I believe 

 they always exist. In my living plant the leaves on the barren shoots are 

 becoming glabrous ; these shoots, aptly described by Haller as loving to rise 

 superior to the umbel, are very remarkable, issuing not only from the stem, 

 but actually from the summits of the umbels, as described in the above quo- 

 tation from the Species Plantarum. These are evidently intended in the figures 

 of the ancient authors, which would otherwise represent the plant very badly; 

 as it is, they are by no means to be praised. 



I venture to suggest the following character and synonyms. 



Euphorbia palustris. 



E. umbella subquinquefida : trifida : bifida : bracteis ellipticis glabris, foliis 



lato-lanceolatis subpilosis serrulatis, capsulis verrucosis pilosis.
