JUANULLOA (named conjointly after G. Juan and 

 Antonio Ulloa, two Spaniards, who travelled in Peru 

 and Chili). STNS. Laureria, Ulloa. OBD. Solanacece. 

 A genus comprising six or seven species of erect or 

 epiphytal stove shrubs, natives of Peru, Columbia, and 

 Central America. Flowers sometimes solitary or few, 

 shortly pedicellate; sometimes several, loosely cymose; 

 calyx large, inflated, coloured. Leaves entire, coriaceous. 

 Juanulloas thrive in a rough peaty soil. Cuttings will root 

 in sand, under a bell glass, in bottom heat. J. parasitica 

 is the one best known to cultivation. 



J. eximia (extraordinary), fl. green, in pairs, very large, droop- 

 ing, between funnel and bell-shaped, about 6in. long. I. oval, 

 firm, glossy, entire, shortly acuminate. Shrub. (B. M. 5092.) 

 This plant really belongs to the genus Dyssochroma. 

 J. parasitica (parasitic).* fl. orange ; racemes dichotomous, 

 pendulous. May. I. oblong, acuminated, alternate, thickish. 

 A. 3ft. Peru, 1840. (B. M. 4118.) 



JUBJEA (named after Juba, a King of Numidia). 

 Coquito Palm of Chili. OBD. Palmce. A monotypic 

 genus, the species being a greenhouse palm. Flowers dark 

 yellow, inclosed in a double spathe, and disposed in 

 branching spikes. Fruit roundish, inclosing a hard one- 

 seeded nut. Jubaea thrives best in a compost of one- 

 half rich loam, and the remainder of leaf mould and sand. 

 It is a very handsome plant, and is well adapted for 

 sub-tropical gardening. Increased by seeds. 



FIG. 345. JUB^A SPECTABILIS. 



J. spectabilis (remarkable).* I. pinnate, spreading, 6ft. to 12ft. 

 long ; pinnae 1ft. to lift, long, about lin. wide, springing in 

 pairs from nearly the same spot, and standing out in different 

 directions ; petioles very thick at the base, inclosed in a dense 

 mass of rough brown fibres. Trunk, when developed, tall, 

 straight, bearing the crown of large leaves, h. 40ft. to 60ft. Chili, 

 1843. The most southern of American palms. From the sap 

 obtained by felling the tree boiled to the consistency of 

 treacle, a syrup, called Palm-honey, is prepared, which is in 

 considerable request in Chili. See Fig. 345. (G. C. n. a., xviii. 401.)

JUGLANDEJE. An order of trees or shrubs with

Jnglandea continued. 



two, three, or six-parted, with a scaly bract; female 

 flowers in terminal clusters, or in loose racemes, with dis- 

 tinct or united bracts; perianth adherent, three to five- 

 parted. Fruit a dry drupe, with a strong and often two- 

 valved endocarp; seed exalbtuninous, two to four-lobed 

 at the base. Leaves alternate, pinnate, stipulate. The 

 wood of several of the species of Juglans is much prized 

 by cabinet makers ; and the bark of Juglans cinerea is 

 used as a purgative in America. There are about five 

 genera and thirty species. Illustrative genera are : Carya 

 and Juglana.
