57. Coriandrum T.' — Flowers * hermaphrodite or polygamous ; 

 sepals minute or conspicuous, very unequal, the larger the more 

 anterior. Petals unequal (anterior larger) obovate, emarginately

 or less highly conical, sometimes depressed (Astomcea^). Fruit either 

 subovoid or subglobose {Eucoriandrum, Keramocarpus '), or broader 

 than long, 2-dymous or 2-giobose {Bifora,^ Atrema,^ Schrenckia,^° 

 ? Gryptodiscus ^^) ; mericarps transversely terete or semiterete.'^ 

 Primary and secondary ridges slightly prominent, the latter stronger 

 {Eucoriandrum) ; the former sometimes flexuose ; or both scarcely 

 conspicuous (Bifora) ; or primary ridges more prominent than 

 secondary {SchrencMa). Carpels within more or less, sometimes very 

 (Bifora) concave. Vittae 0, very thin, irregular or oo (Astomcea) ; the 

 commissural oftener more distinct. Carpophore 2-partite, simple or 

 0« Seed conformed to mericarp, at face more or less concave orbicular.

'^ Exocarp in Astomcea rather fleshy. 



•' Fuernrohria (0. Koch, Linncea, xvi. 356) 

 recently placed near Coriandrum (Boiss. Fl. Or. 

 ii. 919), a genus whose mature fruit is imper- 

 fectly known, but " from its habit, odour and 

 nature of pericarp apparently to be located near 

 Coriandrum." Vittse in furrows are said to bo 

 2-nate ; in the immature fruit they are not dis- 

 tinctly seen. Primary marginal ridges of the 

 mericarps are rather prominent, "the rest 

 obsolete."
