Cull, The most of the species of Quamoclit are beautiful half 

 hardy annual plants. They should be reared on a hot bed ; and 

 about the end of May they may be planted out in an open border, 

 in a warm, sheltered situation, where they will flower freely, and 

 ripen their seed. Some of the more tender kinds may be grown 

 in pots, in the greenhouse, during summer. The perennial her- 

 baceous and shrubby kinds should be treated in the manner re- 

 commended for Batatas, p. 262.

 k-aXXoc, kallos, beauty ; the plants are slender, and very pretty.)

LIN. SYST. Pentdndria, Mcncgynia. Calyx 5-parted. Co- 

 rolla tubularly funnel-shaped, narrow. Stamens inclosed. Style 

 1 ; stigma globose, 2-lobed. Ovarium 4-celled ? 4-valved ; cells 

 1-seeded ? Capsule roundish. Seeds angular. Small erect 

 plants, with quinate or ternate leaves, and flowers resembling 

 those of Quamoclit tulgaris in shape ; except that the stamens 

 are inclosed.

 erect. Peduncles furnished with 2 scale-formed bracteas under 

 the calyx. Calyx muricated ?, with ovate, acuminated segments. 

 Corolla of a reddish-violet colour, tubular, an inch long; segments 

 of the limb ovate, acuminated. Filaments villous at the base.

2 L. TERNA'TA ; glabrous ; leaves ternate ; leaflets linear ; 

 peduncles axillary, 1-flowered. 1. G. Native of Mexico, 

 about Acapulco. Ipomce'a ternifolia, Cav. icon. 5. p. 52. t. 478.

 Corolla tubular, purplish-violet, with ovate, obtuse segments. 

 Stamens villous at the base. 



Ternate-leaved Leptocallis. PI. 1 to \\ foot. 



Cult. The species of Leptocallis are very elegant, slender, 



upright plants, with flowers similar to those of Quamoclit. They 

 will do well in a mixture of loam, peat, and sand, or any rich 

 light soil ; and cuttings of them will readily strike under a hand- 

 glass, in a little bottom heat.

 stem creeping, rarely twining; leaves variable, usually angular, 

 also lobed ; peduncles equal in length to the petioles, or exceed- 

 ing them, 3-4-flowered ; sepals acuminately mucronate, rarely 

 subtruncate, outer ones a little shorter. 1. S. Native of the 

 East Indies, and now cultivated every where within the tropics.

 Root tuberous, edible. Stems prostrate. Leaves cordate. 

 Corolla an inch long, glabrous, white outside, and purple inside. 

 The red-rooted sort is in general cultivation all over the warmer 

 parts of Asia, and very deservedly esteemed one of the most 

 palatable and nutritious roots ; the white-rooted sort is more 

 generally cultivated in other parts. 



The Spanish or Sweet Potatoe is a native of both Indies, and 

 was cultivated by Gerarde, in 1597. He calls the roots potatus, 

 potades, or potatoes, and says they are by some named skirrets 

 of Peru. They flourished in his garden till winter, when they 

 perished and rotted. Batatas were then sold at the exchange in 

 London, and are still annually imported into England from 

 Spain and Portugal. They were, in 1315, the common potatoes 

 of our old English writers, the now common potatoe, Solanum 

 tuberbsum, Lin., being then little known. The tubers of the 

 Batatas are sweet, sapid, and nourishing. They are very com- 

 monly cultivated in all tropical climates, where they eat not only 

 the roots, but the young leaves and tender shoots, boiled. There 

 are several varieties, differing in the size, figure, colour, and taste 

 of the roots, as well as the form, hairiness, and smoothness of 

 the leaves, and colour of the flowers. In warm climates this 

 plant is cultivated in the same manner as we do the potatoe, 

 but requires much more room, for the trailing stalks extend 4 or 

 5 feet every way, sending out large tubers, 40 or 50 to a plant. 

 In the national garden at Paris, the plants are raised on a hot- 

 bed, and, about the middle of May, transplanted into the open 

 ground, where they are earthed up, and otherwise treated like 

 the potatoe. In warm seasons they produce a tolerable crop. 

 M. Thouin considers it a much lighter food than the potatoe, 

 and equally nourishing. In England, Miller observes, the roots 

 must be planted on a hot bed in spring ; and if the plants are 

 kept covered in bad weather with glasses, they will produce 

 flowers, and many small tubers, from the joints ; but if they 

 are exposed to the open air, they seldom make much progress.
