CARICA CAND AMARCENSIS . Mountain papaya. Colom- 

 bian tree, smaller than 0. papaya; presumably hardier, with much 

 smaller, more angular fruits of too acid a flavor for dessert, though 

 very agreeable when stewed; also used for jams and preserves. Ripe 

 fruit has a pleasant, applelike odor. Introduced for test of papain 

 quality and for hybridization with C. papaya. 



CARICA PAPAYA. Papaya. Rapid growing fruit tree, reach- 

 ing 25 feet; in 10 months bears numerous melon-shaped fruits on its 

 trunk. Good varieties deliciously sweet, with characteristic flavor; 

 relished as a breakfast fruit. Easily digested, containing powerful 

 papain ferment. Try as annual in northern Florida and Texas. 

 Easily grown in hothouse. Both sexes required. 



41339. CARICA sp. Papaya. From O. F. Cook, Ollantay- 

 tambo, Peru. A papaya tree of nearly the same size and general 

 appearance as the familiar type, but with the fruits much smaller 

 and more deeply grooved. The flesh is inferior in texture to that of 

 the true papaya, but greatly superior in odor and taste and probably 

 also in keeping qualities. 



CARISSA CAR AND AS. A small, apocynaceous tree or large 

 shrub, with sharp, rigid, forked thorns and oval leaves. The fruit 

 when ripe much resembles a damson; is smaller than that of C. 

 grandiflora. In India it is made into a pickle just before it is ripe, 

 and is also used in tarts and puddings. When ripe it makes a very 

 good jelly. Not so attractive a hedge plant as C. grandiflora, but 

 may prove hardier. 



CARISSA GRANDIFLORA. South African amatungulu. A 



handsome apocynaceous spiny shrub, with glossy green leaves, white 

 fragrant flowers, and ovoid scarlet fruits an inch long. Useful home 

 garden fruit, with a flavor when stewed peculiarly like that of cran- 

 berries. Fruit may be dried like prunes. A most attractive ever- 

 green hedge plant. Stands clipping well, and its spines make it 

 quite impenetrable. 



CARYOPTERIS INCANA. Handsome blue-flowered deciduous 

 bush, valuable both as a fall-blooming ornamental shrub and as one 

 of the best of late-flowering bee plants; of spreading habit, 4 to 8 

 feet high; the whole plant, except the old wood and the upper sur- 

 face of the dull green leaves, covered by a close gray felt. Flowers 

 bright violet-blue, produced in September and October in numerous, 

 axillary clusters.
