 nal or axillary, naked or leafy paniculate cymes or

 many as the sepals, 2-cleft or rarely laciniate or only

 sepals one-half or two-thirds 

 as long as the petals. May,

 This and the next are desir- 

 able for dry banks where

 stemmed, hardy perennial 

 plant not usually over 6 in.

 lanceolate, usually about 1 

 in. long: fls. white, in terminal 

 or lateral scarious bracted

 inAmer. B.B. 2:23. Var. 

 aurea, Hort., GOLDEN STITCH- 

 WORT, has pale yellow Ivs. and is lower and more

 grass does not grow well. 



BB. Lvs. ovate. 



media, Linn. CHICKWEED. Fig. 3686. Alow, decum- 

 bent annual weed common in all rich, moist, cult, soils, 

 especially troublesome during the cooler months of the 

 growing season and in frames, and the like, during 

 winter. Lvs. 2 lines to !}/ in. long, the lower petioled, 

 the upper sessile : fls. axillary or in terminal leafy cymes; 

 sepals longer than the petals. Eu., Asia; naturalized. 

 B.B. 2:21. It is considered to be a good fall and winter 

 cover-plant in orchards and vineyards, but is never cult. 

 It is a surface-rooting plant. jr \y BARCLAY.

 ceous stamens) . Syn. , Roxburghia. Stemonacese; by some 

 the family is called Roxburghiacese. Tall climbing peren- 

 nial herbs, from a tuberous fusiform root, suitable only

 ovate, 3-9-costate: fls. solitary, or few and subracemose;
