CONVOLVULUS 



COOPERIA 



Scammdnia, Linn. Hard}' 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. 



BB. Stem erect or ascending, silky. 



Cneorum, 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. olecefolins. 



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. linearis). Many plants now passing as 

 G. olecefolius are C. Cneorum. The latter may be dis- 

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

 and lighter colored blossoms. 



tricolor, Linn. (G. minor, Hort.). Fig. 544. Hardy 

 annual : stem trailing, ascending 6-12 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- 

 tata, 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. 



C. althceoldes, Linn. (C. Italicus, Roem. & Schult.). Stem 

 prostrate, scarcely twining : upper Ivs. pedatifid; lower ovate- 



543. Convolvulus Sepium 



R.H. 1848:121. Var. compactus. Dwarf, and valuable 

 for pot culture. Gt. 47, p. 635. A 5-petaled form is also 

 recorded. F.S.8:116. 



aureus superbus, Hort. A tender perennial, but may 

 be treated as an annual, since it flowers the first season 



544. Convolvulus tricolor. Natural size. 



cordate, crenate, silvery: Us. pink. May- Aug. Mediterranean 

 region. B.M.359. F.S.10:1021(as var.argyreus). R.H. 1864: 111. 

 C. arvensis, Linn. Slender perennial trailer, 1-3 ft. long, gla- 

 brous or nearly so: Ivs. ovate-sagittate or hastate, variable: 

 fls. white or pink. Eu. and E. Asia. Naturalized in old fields 

 through the Atlantic states and Calif. A troublesome weed. 

 C. Dahiiricus, Herb. (Calystegia Dahuricus, Fisch.). Hardy de- 

 ciduous twiner, 3-6 ft.: Ivs. oblong-cordate, shortly acute: fls. 

 pink or rose-violet. June, July. N. Eu. B. M. 2609. F. S. 

 10:1075. G. Canariensis, Linn. Greenhouse evergreen: Ivs. 

 oblong-cordate, acute, villose : fls. violet-purple : peduncle 1-6- 

 fld. Canary Islands. B. M. 1228. C. erubescens, Sims (C. 

 acaulis, Choisy). Tender biennial: Ivs. oblong, hastate, the 

 basal lobes toothed: fls. small, 5-lobed, rose-pink. Australia, 

 B.M. 1067. C. macrostegius, Greene. The plants in the trade 

 under this name may be referred to C. occidentalis. C. major. 

 Hort., not Gilib.= Ipomosa purpurea. C. ocelldtus, Hook. 

 Stove evergreen : limb of the corolla white, 5-angled : throat 

 reddish purple : Ivs. sessile, linear, acute, 1-veined, villose. S. 

 Afr. B.M. 4065. g< W . FLETCHER. 



COONTIE of S. Fla. is Zamia integri folia. 



COOPERIA (after Joseph Cooper, English gardener). 

 Amaryllidacece. 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 

 Zephyranthes. Lately a new and little-known plant 

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

 " bright green " fls. 



A. Neck of bulb short: perianth tube long. 

 Drummondii, Herb. EVENING STAR. Bulb roundish, 

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

 erect, 1 ft.' long : peduncle slender, fragile,. hollow %-l 

 ft. long : spathe l%-2 in. long, 2-valved at the tip : 

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

 tinged with red outside : segments oblong, cuspidate. 

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

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

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