NATURAL HISTORY OF PLANTS. 



ChcBrophyllum {Anthriscus) silvestre. 



ternatipinnate leaves, and whose compound umbels have few-flowered, 

 often capituliform umbellules, with an involucel of numerous bracts. 

 The petals are entire, flat ; and the stylophores, depressed and 

 concave within, are exterior to two long subulate stylary branches. 

 The fruit, oboval, compressed perpendicularly to the partition, has 

 five linear little-developed ridges and numerous vittae. The carpo- 

 phore is indistinct and the mericarps curve from summit to base ; 

 the face of the seed is concave. In Orogenia, which appears to us to 

 constitute a section of the same genus, this concavity has three 

 vertical ridges, one middle and two marginal, and the whole plant is 



said to have only two or tliree 

 long petiolate leaves. 



In Oliveria, a Levant 

 annual whose habit and the 

 general appearance of its in- 

 florescence have caused it to 

 be referred to Lagcecia, though 

 its umbels are really com- 

 pound, there are five narrow 

 sepals and petals much in- 

 flexed and adnate at the sum- 

 mit, surmounted by two wide 

 salient auricles (correspond- 

 ing to the margins of the 

 organ). The two erect styles 

 are accompanied in their 

 lower half by long conical 

 stylopods, and the fruit is 

 oblong, much compressed per- 

 pendicular to the pai-tition, 

 covered with thick hairs. The 

 primary ridges are little pro- 

 minent and the vittae solitary. 

 The seed is more or less 

 concave within. The bracts 

 of the involucels are wide and 

 three-lobed. Apart from its inflorescence, this genus nearly approaches 

 the following. 



These form a small group Scandicinece or CluerophijUece , The frait
