Scammdnia, Linn. Hardy perennial trailer, decidu- 

 ous : stem angular, glabrous : Ivs. cordate-sagittate, 

 grey-green, the lobes entire or dentate: sepals glabrous, 

 ovate, obtuse; corolla white, creamy or light pink. Asia 

 Minor. — The large tap-roots supply the resinous cathar- 

 tic drug scammony.

Cnedrum, Linn. Stem shrubby, half-hardy, 1-i ft. 

 high : Ivs. persistent, lanceolate or spatulate, silky grey : 

 inflorescence a loose panicle, 1-6-fld.: lis. white or 

 tinged with pink, borne freely during the summer. S.

 late, acute, slightly villose: fls. bright pink, borne freely 

 in loose, umbellate panicles in the summer. Gref r. 

 B.M. 289 (as C. linearis). -M&iiy plants now passing .-i, 

 C. olecefolius are C. Cneorum. The latter may be di- 

 tinguished by its broader, blunter, silvery-villose h - 

 and lighter colored blossoms.

 S. Eu. B.31.J7. -Our ..f the best annuals for the home 

 border. Earh plant i'..\ iivs a ground space of 2 ft., and 

 blooms eoutiiiuuusly thi-uughout the summer. Flowers 

 remain open all day during pleasant weather. There 

 are many variously striped and spotted forms of this 

 popular annual, none of which surpasses the type in 

 beauty. A variety with pure white fls. is attractive. 

 Other well marked horticultural forms are : Var. vit- 

 t4ta, prettily striped with blue and white. F.S. 3:298.

 recorded. F.S. 8; 116.

C00F£RIA (after Joseph Cooper, English gardener). 

 AmarxiUid&ceai. A genus of only two or three species 

 of tender, bulbous plants from Texas, with the habit of 

 Zephyranthes but night-blooming (which is anomalous 

 in the order), and with erect anthers, while tliose of the 

 latter are versatile. The fls. are fragrant, solitary, 2 in. 

 or more across, waxy-white, tinged red outside, and 

 more or less green within. The Ivs. appear with the fls. 

 in summer. They are long, narrow, flat and twisted. 

 The bulbs should be taken up in autumn and stored 

 during the winter in dry soil. Culture easy and like 

 Zephyranthes. Lately a new and little-known plant 

 has been offered by the trade, C. Obenvetteri, with 

 "bright green" fls.
