given as much air ag possil)le. It is well to brin^ the 

 Ericas out of the greenhouse as early in the spring as 

 possible. The pots should be plunged inagoud situation. 

 where plenty of air and sunlight can be hud. They sliould 

 be wintered in a greenhouse extremely well ventiUited, 

 and a temperature not higher than from 40° to -45° F. 

 When in bad the plants should not be allowed to dry out 

 too much. Once would be enough to cause the loss of 

 all the buds. Very often the Heaths are attacked by a 

 disease similar to mildew, caused by an excess of hu- 

 midity in the air. As this disease is very contagious, it is 

 well, as soon as noticed, to use Rul]iliur "in powder or sul- 

 phate of copper in solution until the plants are rid of it.

1. c&mea, Linu. [E. herfx^cca, Linn.). Height G in.: 

 Its. in 4'3 : inflorescence lateral : corolla broadly bell- 

 shaped: anthers exserted: ovary glabrous. Mar.-Mav. 

 Alps. L.B.C. 15:1452. B.M. 11.' Un. 54:1177 (a charm- 

 ing picture). The bright rosy-rid. form is the best and 

 most striking. There are pale red and pure white varie- 

 ties. The most popular of all hardy Ericas. Very easily 

 prop, by division. We should try F. Mediterranea, var. 

 hybrida, Hort., said to be across with E. earnea, and in 

 England thriving almost as well in loam as in peat. See 

 Gnr 55, p. 125, and 54, p. 2G2. 



2. vigans, Linn. Cornish Heath. Lvs. in 4's or o's: 

 sepals small, ovate, obtuse ; corolla ovate-bell-shaped; 

 anthers ovate-oblong, 2-parted, exserted : ovary not 

 hairy. W. Eu. and Medit. — Fls. pale purplish red. 

 Grows 3^ ft. in England; 1 ft. with J. W. Manning, 

 Reading, Mass. Var. alba has white fls. Var. capit^ta, 

 grows 1-2 ft. high with Meehan at Germantown, Pa., 

 and has "small whitish tis. with a purplish tip." 



3. stricta, Don. Corsican Heath. Lvs. in 4's, a little 

 more erect than in Nos. 3 and 5 : sepals lanceolate, ob- 

 tuse; corolla ovoid-oblong, narrowed at the throat; an- 

 thers awl-shaped or awued, included : ovary densely 

 covered with long, roxigh hairs. Corsica. — Attains 4 ft.

 mantown, Pa. Branches strict, rigid.

 Heath. Lvs. in 4's, margin folded back: fls. rosy; se- 

 [tais ovate-lanceolate, ciliate ; anthers awl-shaped or 

 awned, included : ovary with sliort, soft hairs. W. Eu.

 Manning, at Reading, Mass., about 8 in. 



5. hyemalis, Hort. Fig. 771. Written also hiemalis. 

 Watson thinks it may be a winter-flowering form of F. 

 perspicua, figured in L.B.C. 2:102 and 18:1778 as F. 

 Linnienna . Fls. rosy pink, tipped white. Var. dlba has

 in Sept. G.F. 5:137. On. 41:85(i. H. D.Darlington 

 says it is very distinct from F. perspicua . 



G. praestans, And. {F. ParmentieHi, Loddiges). Lvs. 

 in 4's, souiewhat incurved: bracts crowded : fls. nearly 

 sessile, white, faintly flushed pink at base, in terminal
