character of the plant. By mountain-plants, I here 

 wifli to be underftood to mean all thofe which 

 grow in Candy and parched fituations, on hillocks, 

 in rocks, en fleep ridges by the highway's fide, 

 in walls, and, in one word, at a diftance from

The feeds of thiflles, of blue-bottles, of dande- 

 lion, of fuccory, and many others, are furniihed 

 with pinions, with plumes, with tufts, and various 

 other means of rifing, which convey them to pro- 

 digious diftances. Thofe of the grafles, which like- 

 wife travel very far, are provided with a light 

 chaffy coat, and with bearded hufks. Others, fuch 

 as thofe of the yellow gilly-flower, are cut into 

 thin fcales, and fly by the flighted breath of the 

 wind, and plant themfelves in the moftinconfider- 

 able crevice of a wall. The feeds of the largeft 

 mountain-trees are no lefs volatile. That of the 

 maple has two membranous pinions, fimilar to the 

 wings of a fly. That of the elm is cafed in the 

 midft of an oval thin leaf. Thofe of the cyprefs 

 are almofl imperceptible. Thofe of the cedar are 

 terminated by broad and thin plates, which, in 

 their aggregated ftate, compofe a cone. The 

 grains are in the centre of the cone ; and when 

 arrived at maturity, the thin membranes, to which 

 they adhere, feparate from each other, like the
