DECANDRIA. PENTAGYNIA. Spcrgula. 



This has been considered by some of our most accurate bo- 

 tanists as the S. laricina or the S. saginoitjes of Linnaeus, but Mr. 

 Afzelius informs me it is neither, but a kind of intermediate plant 

 between the two. The S. saginoides is more branched, has swol- 

 len knots at the joints of the stems, with a remarkable contrac- 

 tion just under the knots ; it is also a larger plant, is destitute of 

 hairyness, and its flowers always contain 10 stamens. The S. 

 laricina has the leaves in opposite pairs, with bundles of young 

 leaves or branches in the axilla?. The fruit -stalks are smooth 

 and furnished with floral leaves. The calyx leafits are 3-fibred f 

 the stamens are always 10, and the flowers much larger than those 

 of the S. subulata.

 Mr. Norris has discovered this plant, of a diminutive size 

 and comparatively glaucous hue, in a very unusual situation. 

 He says it grows near Bromham, Wiltsh. upon the southern and 

 sun-burnt brow of a chalky eminence called Morgan's-Hill, 

 within a furlong south of the ancient Wansdike; living in a 

 spot most parched and dry, (among loose flints, &c. and asso- 

 ciating with the Sedum acre, Poa rigida, Phyteuma orbicularis 



and Asperula cynanchica).
