Q 



QUAMASIA (quamash, the Indian name). Liliaceae. 

 A name given by Rafinesque in 1818 to the plants that 

 Lindley, in 1832, called Camassia. On the principle of 

 fifty years of accepted usage, the name Camassia is 

 retained in the "nomina conservanda" of the Inter- 

 national Botanical Congress (Vienna), and under that 

 name the plants are treated in Vol. II. One species, 

 variously known as Camassia esculenta, Quamasia 

 fsculenta and Q. hyacinthina, is native in the eastern 

 United States, but the most showy species are from the 

 Pacific side of the continent. 



QUAMOCLIT (Greek, a dwarf kidney bean). 

 Including Calboa and 3/lruz. Conroiruiicea?. Annual, 

 or in tropical regions some perennial twining vines; 



most of them of 

 easy culture, of 

 rapid growth, and 

 with a profusion of 

 small flowers. 



The genus differs 

 from all other Con- 

 volvulacese by its 

 axillary often 2- 

 forked clusters of 

 fls.. the thickened 

 pedicels of some 

 species, the slender 

 corolla-tube not ex- 

 panding at the base, 

 the limb of the co- 

 rolla salverform or 

 cup - shaped, sta- 

 mens and st3 T le ex- 

 serted and often 

 declinate. A bout 

 10 species. Q. pin- 

 nate is the best- 

 known species, 

 often used to ad- 

 vantage upon 

 arbors, verandas, 

 walls, or on screens 

 in the conserv- 

 atory. 



A. Sepals without 

 awns; pedicels 

 thickened: Ixs. 

 pi nnately 

 divided. 



pinnata, Bojer 

 (Ipomdea Qudmodil, 

 Linn. Q. vulgaris, 

 Choisy. Q. Qudmoclit, Brit.). CYPRESS- VINT:. INDIAX 

 PINK. Fig. 3301. St. smooth, slender, twining to a 

 height of 10-20 ft.: Ivs. short-petioled or sessile: pedun- 

 cles few-fld., commonly much longer than the petioles: 

 corolla 1-1 J'2 in., long, scarlet, the tube narrowly funnel- 

 form, inflated above; the limb nearly flat, 5-lobed. 

 July-Oct. Naturalized from Trop. Amer., Va. to Fla., 

 west to Kans. and Texas: sparingly escaped from cult, 

 farther north. B.M. 188 (as Convolvulus Nil); 244. Gn. 

 29, p. 33. Beautiful in fl. and foliage but usually does 

 not succeed well in the N. unless started early in the hot- 

 house and transplanted. Var. alba, Hort.. has white fls.

AA. Sepals aimed: k>s. entire or lobed.

cup-shaped, J^tn. broad or broader. 



coccinea, Moench (Ipomcea coccinea, Linn.). STAR 

 IPOM02A. Fig. 3302. St. freely twining for 10 ft.: Ivs. 

 slender-petioled, entire or angulate, acuminate: pedun- 

 cle 2-6 in. long, few- to several-fid.; corolla J^-%in.

 yellow throat. Aug.-Oet. Apparently naturalized 

 from Trop. Amer., on river banks in the Middle and 

 South Atlantic states; probably indigenous to X. Mex. 

 and Ariz. B.M. 221. Fls. are produced in abundance, 

 but are very small.

 guinea, Hort.). Fig. 3303. This Plains form of the 

 species has angulate, 3-lobed or even 3-5-parted Ivs., 

 and fls. usually larger. B.R. 9. B.M. 1769. I.H. 

 41, p. 159. It is superior to the type for ornamental 

 purposes. 



Var. luteola, House (Ipom&a luteola, Jacq. Ipomaca 

 cocdnea var. lutea, Hort.). Fls. yellow, an inch long. 

 Varies to orange in color.

 cent: peduncles

 the middle lobe constricted be- 

 low: peduncles elongated, sev- 

 eral-fld. : corolla about 1 in. long, 

 the yellowish tube expanding above into a scarlet, 

 deeply Mobed limb, the exserted stamens elongated 

 and declinate. S. Mex. 



BBB. Corolla-limb cylindrical and bent, longer than the 

 tube, yellow tinged with red.

 Don. Ipomaea rersicolor, Meissn.). A vigorous peren- 

 nial climber, 15-20 ft. high: Ivs. with a cordate base,
