 umbels 15-30, angular, roughish at the angles. Umbellules with 

 20-30 flowers. Mericarps with 5 prominent ribs. Stylopodium

 fruticose at the base ; leaves ternately decompound : leaflets

 decompound : leaflets ovate, cut : segments linear, obtuse ; in- 

 volucra and involucels of 4 very short leaves. $ . G. Native

35 S. PRA'GILE (Gouan. ill. p. 15.) stem unknown ; leaves 

 tripinnate ; leaflets ternate, brittle, articulated : segments linear ; 

 sheaths large, 2-lobed at the apex ; involucra none ; umbels 12- 

 rayed ; involucels of 7-9 leaves, which are 3 times shorter than 

 the umbellules. $ . H. Native country unknown, as well as 

 the flowers and fruit. Gouan cites under this plant the figures 

 in J. Bauh. hist. 3. p. 18. f. 2. Clus. hist. 2. p. 196. f. 1. 

 Tabern. icon. t. 97. f. 2. but these figures are very different 

 from each other, and therefore the plant is very doubtful. 



Brittle Meadow-saxifrage. PI. li foot. 



Cult. The plants of this genus are of easy culture ; they re- 

 quire sandy or chalky soil, and are easily increased by seeds. 

 Those species marked perennial prove seldom more than bien- 

 nial when cultivated in gardens. 



LXXI. LIBANOTIS (from \ifiavoc, libanos, incense, and 

 not from Mount Libanon, as the name would imply ; L. vulgaris 

 is supposed to exhale an odour like incense). Crantz. austr. p.

LIN. SYST. Pentdndria, Digynia. All as in Seseli but differs 

 in the lobes of the calyx being slender (f. 55. F. c. a.), subu- 

 late, elongated, coloured, and deciduous, with the base hardly 

 remaining ; and in the involucra and involucels being both 

 usually composed of many leaves. Leaves pinnate or bipinnate : 

 leaflets ovate, cut or multifid : lower ones usually decussate.
