The beauty of Passifloras is well known ; they aro remarkable for the singular arrangement of the stamens 

 and pistillum upon a column surrounded by several lines of circumvallation, formed by as many rows of 

 barren thread-like colored stamens, which are popularly called the rays. The fruit of several species of 

 passion-flower is filled with pleasant acidulated pulp, on which account they are eaten as dessert fruit. It is 

 not known that they possess any medical properties. The station of the order is not settled ; it is undoubtedly 

 very near Cucurbitkceaj. Cuttings and seeds.

Nothing is known of the qualities of this order. It consists of succulent cut-leaved plants, generally covered 

 with asperities or rigid stinging hairs, and yellow or white flowers. They are all natives of America, and 

 handsome annuals. A very few of them are climbers. Cuttings and seeds.

This order consists only of two genera, Turnena and Piriqui-ta ; they are small suffruticose or herbaceous 

 plants, chiefly natives of tropical America, with alternate exstipulate leaves, and axillary yellow flowers, 

 emulating those of Helianthemum. The order is chiefly distinguished from Leases in the stamens being 

 equal in number with the petals, and inserted at the bottom of the calyx, not in the throat of the tube as in 

 that order. Cuttings or seeds.

With the exception of Tallnum and Calandrinia, and a few species of Claytoma, the whole of this order 

 consists of insignificant weedy plants, of no beauty, and little use. ClaytomYz perfoliata and common purslane, 

 which are occasionally used as salads, being the only species of a useful kind. They are chiefly herbaceous 

 plants, frequenting dry barren situations, or the sea-shore of all parts of the world ; all are insipid and 

 inodorous, and destitute, as far as is known, of medicinal properties. Cuttings and seeds.

This order consists chiefly of small insignificant weedy, herbaceous, or suffrutescent plants, with the 

 exception of Corrig'ipla, 2'elfephmwz, /ll^cebrum, and a few species of Lahaya. The flowers are small, 

 white or greenish-white, sometimes axillary and sometimes disposed in terminal cymes, the leaves are small 

 and entire. The order differs from Portulaces in the stamens being opposite the lobes of the calyx, not 

 alternate with them. Cuttings, seeds.

These are all plants with a greater or less degree of succulence; the Mesembryanthemums and Hymen6- 

 gyne are well-known dry-stove plants, many of which are beautiful in the highest degree. Of the former
