CONVOLVULUS 



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 scaramonj'. 



BB. Stem erect or ascending, silky. 



Cnednun, Linn. Stem shrubby, half-hardy, 1-4 ft. 

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

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

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

 Eu.— Valuable as a pot-plant for greenhouse or window 

 decoration, or trained to a warm wall. Confused with 

 C. oleiefolins. 



oleaefdlius, Desr. Tender perennial: Ivs. linear-lanceo- 

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

 in loose, umbellate panicles in the summer. Greece. 

 B.M. 289 (as C. linen ris}.-M&Tiy plants now passing as 

 C. olewfolius are C. Vneorum. The latter may be dis- 

 tinguished by its broader, blunter, silvery-villose Ivs. 

 and lighter colored blossoms. 



tricolor, Linn. (C. mhior, Hort.). Fig. 544. Hardy 

 annual : stem trailing, ascending G-12 in., angulate, 

 densely covered with long brownish hairs: Ivs. linear- 

 oblong or subspatulate, obtuse or rounded at the apex, 

 usually pubescent but sometimes glabrous, the margin 

 ciliate towards the base; peduncle 3-fld., exceeding the 

 Ivs.: sepals ovate, lanceolate, villose, acute: limb of the 

 corolla azure-blue, throat yellow, margined with white. 

 S. Eu. B.M. 27.— One of the best annuals for the home 

 border. Each plant covers a ground space of 2 ft., and 

 blooms continuously throughout 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- 

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



from seed : stem trailing or twining, 4-5 ft. long : fls. 

 golden. Valuable as a greenhouse climber and for 

 hanging baskets.— Not sufficiently described for identi- 

 fication.

S. W. Fletcuer. 



COONTIE of S. Fla. is Zamia integrifolia. 



COOPfiBIA (after Joseph Cooper, English gardener). 

 AmttrifUiddce(e. 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 those 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 

 Zephvranthes. Lately a new and little-known plant 

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

 "brigbt green" fls. 



A. Xeek of bulb short: perianth tube lonij. 



Dnimmondii, Herb. Evkning Star. Bulb roundish, 

 1 in. thick, with a short neck : Ivs. narrowly linear, 

 erect, 1 ft. long : peduncle slender, fragile, hollow M-1 

 ft. long: spathe VA-2 In. long, 2-valved at the tip: 

 perianth tube 3-5 in. long ; limb 'A-l in. long, white, 

 tinged with red outside : segments oblong, cuspidate. 

 Var. cUorosdlen, Baker, has a perianth tube stouter and 

 tinged with green: limb longer and less wheel-shaped : 

 Ivs. a little broader. B.M. 3482.
