many of them are apt to damp off in the winter in this kind of 

 situation, unless taken great care of, therefore the safest way 

 to preserve them is to keep a plant or two of each of the 

 perennial kinds in small pots among other alpine plants ; they 

 thrive best in a mixture of sand, loam, and peat, and the pots 

 should be well drained with potsherds ; they are easily increased 

 by dividing the plants at the roots, or by seed. The annual and 

 biennial kinds, having rather a weedy appearance, are only fit for 

 botanic gardens ; they should be sown in the open border or on 

 rock-work. D. nemoralis and D. muralis require to be sown in 

 a shady situation. 



XXXIV. ERO'PHILA (from cp, er, the spring, and <j>i\cu,

Cult. These pretty little annual plants should be sown in the 

 autumn in the sunny parts of rock-work, where they should be 

 allowed afterwards to scatter themselves. Being very early 

 flowering plants, therefore very desirable. 



XXXV. COCHLEA'RIA (from cochlear, a spoon ; the leaves 

 of most of the species are hollowed like the bowl of a spoon). 

 Tourn. inst. 215. t. 101. Lin. gen. no. 803. Lam. illust. t. 

 558. D. C. syst. 2. p. 358. prod. 1. p. 172.

 globose or oblong, with ventricose valves. Seeds many, not 

 margined. Calyx equal at the base, spreading. Petals entire. 



Stamens toothless. Annual or perennial herbs, usually smooth 

 and fleshy, but sometimes they are puberulous, with scattered, 

 short, simple, or 3-forked hairs. Form of leaves very variable ; 

 radical ones usually stalked; cauline ones often auriculately- 

 sagittate. Racemes terminal ; pedicels bractless, spreading, fili- 

 form, or somewhat angular. Flowers white, except in one 

 species which is lilac.. The sections of this genus may constitute 

 as many distinct genera.

 cles globose, somewhat 4-sided at the base, with rather stiff valves. 

 Dissepiment bounded by narrow linear areolae. Filaments 4, 

 jointed at their middle. Style short ; stigma 2-lobed. This 

 section is considered of sufficient importance by Mr. Brown to 

 constitute a distinct genus.
