THE MUSTARD FAMILY. 203 



D. h'achycdrpa, short-fruited whitlow grass, we find through dry fields 

 and on hillsides. It is a rather insignificant annual and grows usually from 

 two to five inches high. About its base the ovate leaves are tufted, while 

 on the stem they are smaller and sessile. Sometimes the tiny fiowers are 

 without their yellow petals. 



D. vcrna, vernal whitlow-grass, is the very common little member of this 

 genus which has come to us from Europe and here inhabits waste and 

 sandy places. Its leaves are all tufted about the base, and usually droop on 

 the approach of rain. The ascending scapes are terminated by racemes of 

 many tiny white flowers with two-cleft petals.

 oval, long clawed. Stimiens : six, two of which are shorter than the otliers. 

 Pistil: one. Capsule: slender, recurved, two-valved. Leaves: simple; slightly 

 clasping; oval ; entire. Stem : erect ; one to two feet high. 



The warea, as in our botanies this pretty plant is called, seems to bloom 

 rather pretentiously for a mustard; indeed sometimes so delicate in tint 

 and texture are its petals that they quite throw a slur of coarseness over 

 those of its near relatives. But then its home is in the sand hills of the far 

 south, Florida, where somehov/ all is tuned to a high pitch of loveliness.

Flotuers : growing in racemes which in fruit become elongated, their pedicels 

 slender and pubescent. Petals : entire. Pods : inflated; round; two-valved ; pro- 

 jecting the style and covered with minute hairs. Leaves : simple; growing thickly 

 about the base and on the stems, the former spatulate, or obovate and tapering into 

 petioles; the latter partly clasping, lanceolate or auriculate with two lobes at the 

 base; irregularly dentate, rough and pubescent. An ascending, leafy and pubes- 

 cent herb. 



Very local indeed is this biennial, it being mostly found near Nashville, 

 Tennessee, where in a rather lowly, although ascending way, it grows on the 

 hillsides.
