CARICA CANDAMARCENSIS. Mountain papaya.  Colombian 
tree, smaller than C. 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, reaching 
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, Ollantaytambo, 
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 CARANDAS. 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 evergreen 
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 surface 
of the dull green leaves, covered by a close gray felt. Flowers
bright violet-blue, produced in September and October in numerous,
axillary clusters.
