 Scropkularidcese. A half-dozen South American and 

 New Zealand plants that sometimes are included with

 list) is sometimes cultivated as a greenhouse plant in 

 the Old World. They differ from Calceolaria in having 

 a ringent corolla without a saccate hp. 



JDANULLOA (George Juan and Antonio Ulloa, 

 Spanish naturalists who traveled in Chile and Peru). 

 Solanacese. About 10 species of shrubby plants, more or 

 less epiphytic, from Cent. Amer. to Peru, sometimes 

 mentioned in horticultural literature as suitable for 

 growing in the warmhouse. Erect or diffuse and pre- 

 ducing runners or decumbent branches, glabrous or 

 tomentose: lvs. thick and entire: fls. yellow or red, 

 solitary or in clusters; calyx colored, large; coroUa 

 tubular, sometimes ventricose and contracted at the 

 throat, with small broad lobes; stamens inserted in 

 lower part of corolla-tube: fr. an indehiscent suc- 

 culent or dry berry. J . aurant'iaca, Otto & Dietr. (J. 

 parasitica, Hook.), is the species most likely to occur 

 in cult. It is a glabrous shrub with herbaceous young 

 branches: lvs. alternate, sometimes 2 together and very 

 unequal, 2-5 in. long, oval or obovate, obtuse, short- 

 petioled: fls. terminal on drooping branches in a sort 

 of leafy raceme, show>', orange; calyx fleshy and large, 

 5-angled, loose on the corolla, the latter about a 

 third longer and tubular, enlarging upward, and with 

 a limb of 5 short rounded segms. Peru, where it is said 

 to be epiphytic; but said to thrive well in a warmhouse 

 in earth. B.M. 4118. H.U. 2, p. 321. l. H. B.
