NATURAL HISTORY OF PLANTS. 



Cartim Fetroselinum. 



depression between them. Each furrow has a solitary vitta and the 

 commissure has one on each side. A carpophore, bifurcate to a 

 variable extent, bears the mericarps. The seed is slightly compressed 

 at the sides, channeled, and its face is flat or traversed by a furrow 

 or a salient ridge along the median line. G. Carui and its allied 

 species ^ are annual or perennial herbaceous plants, with pinnate or 

 decompound ternatipinnate leaves. The involucres of the umbels, 

 sometimes a little irregular, are formed of a few bracts, or sometimes 

 nil ; the bracteoles of the involucels are indefinite in number. 



Some annual species of Carum have bifid petals, furnished with a 



transverse median fold whence proceeds a 

 small tongue or lobule ; of them has been 

 made a genus Ptychotis.^' Others, as the 

 common Parsley (fig. 120), annuals or 

 biennials, have a little shorter glabrous 

 fruit and yellowish or greenish flowers ; 

 they constitute the genera Petroselimim,^ 

 Wydleria,^ and Ridolfia^ Trachyspermum^ 

 consists of annual or biennial Ptychosis 

 with fruit covered with papillae or hairs. 

 In Brachyaphim ^ the fruit is shorter than 

 in the preceding species and quite double; 

 in Trachysciadium,^ it is rather more elon- 

 gate and hispid. In Micro sciadium,^ it is 

 also elongate and narrower, with more 

 prominent ridges, and the stylopods irregularly concave ; this type 

 is rendered inseparable from Garum by the intervention of Falcaria ^° 

 Rivini, which has nearly the same disk and rather more developed 

 sepals, but otherwise all the essential characters of Garum,^^
