 Twiggy, nearly erect shrub with -i-angied glabrous stiff 

 hranchlets: Ivs. opposite, small, with 3 little ovate cili- 

 ate Ifts., the entire foliage falling in autumn or when 

 the growth is completed: ils. solitary, in early .spring (or 

 winter), from long, scaly buds, subtended by several or

 most interesting plant, reminding one of Forsythia when 

 in bloom. Hardy south of Washington, and blooming 

 nearly all winter. With protection, it will stand as far 

 north as Hudson river valley, and bloom very early in 

 .spring. In northern glasshouses, used mostly as a late 

 winter and early spring bloomer. Strong-growing speci- 

 mens need support.

 /■ymes umbel-like: petals distinct, ,S times as long as the 

 calyx; stamens 8-10. Tropics; naturalized in Jamaica 

 and common there.— Cult, at Santa Barbara, by Fran- 

 ceschi, who says its curiously divided leaves and scarlet 

 Howers are very ornamental, and adds that it is called 

 "Coral Bush." 



Curcas, Linn. Frknoh Phvsic Nct. Subshrub, 0-12 

 ft. high : Ivs. subcordate-roundish, angular or obsoletely 

 :-!-5-Iobed, glabrous ; stipules deciduous : corolla 5-

 says it grows 20 ft. high. 



gossj-pifolia, Linn. Subslirub, u few feet high: Ivs.

JEFFERSONIA (after Thomas ..Ipfferson, third presi- 

 dent of the U, S.). Berheridiicrfr. A genus of 2 species, 

 one of which is a native hardy ht^rbaceous perennial 

 plant, growing about 8 in. liigh, with characteristic foli- 

 age and a naked scape, bearing a solitary white (some- 

 times reddish) flower in May. DistinguisJied from tlie 

 group of cultivated allies mentione<l under Epimediuni 

 l>y the following characters: Ivs. 2-parted : sepals 4; 

 petals 8, larger than the sepals, and flat ; stamens H : ovules 

 in an indefinite numl)er of series along tlie venter. The 

 capsule is half-circumacissiie near the top, making, with 

 the scape, nn object resembling a pipp. Mn. 5, p. 22(:.

JUB.ffiA (after Juba, king of Numidia). Palmacefp. 

 Tliis includes the Wine Palm of Chile, J". apectahiU.^, 

 which in this country is cult, outdoors in S.Calif, and 

 in the North under glass. "It is one of the hardiest 

 l)alms," says Franceschi, "and can endure drought and 

 many degrees of cold. If liberally treated, it makes a 

 large tree in a few years." A full-sized trunk yields 

 about 90 gallons of sugary sap, which is boiled by the 

 Chileans and called palm honey. There is some daDger 

 of the species being exterminated in Chile. The fruits 

 look like diminutive cocoanuts, and are called Coquitos, 

 or by the trade "Monkey's Cocoanuts." In Europe, it is 

 cult, under glass, and also used for subtropical bedding. 



Jiib(pa Hpt'ctabiUs is a handsome and satisfactory 

 palm for the cool palm house, where it would be treated 

 in common with such plants as Charnarops hiimili.'^, 

 the Sabals and Euterpe montavd, which may be grown 

 well in a night temperature of 50°, providing the plants 

 are properly established. In general appearance, J. 

 specfdbi/is reminds one of some kinds of Phoenix, and, 

 like them, does not show the true character of its foli- 

 age in avery small state, the seedling Jubfea producing 

 several simple Ivs. before developing foliage of the pin- 

 nate type. Ln Jubfea, however, the lower pinna? do not 

 r(-.'vert to spines, as is usually the casn with Plicenix, 

 niid the pimue are also arranged irregularly on the mid- 

 rib, thns giving the fronds a feathery effect. The cul- 

 ture of pTubfpa is by no means difhcuit. propagation be- 

 ing effected by means of imported seeds, which usually 

 give a fair percentage of germinatiou, providing tliey 

 are started in a warmhouse and kept moist. The seed- 

 lings should be potted as soon as the second leaf ap- 

 pears, and kept in a warmhouse until they are large 

 enough for a 4-inch pot, and from this time forward 

 cooler treatment will give the best results, always re- 

 membering tlie fact that while many palms (and Jubira 

 nniOTig the number), will bear ranch neglect, yet the 

 best results are only to be had by giving plenty of nour- 

 ishment.
