This is a strong, vigorous vine, very suitable for arbors and trellises. It is not commonly found in Hawaii; however, a very fine specimen of its kind is growing in Dr. St. D. G. Walter's garden in Honolulu. The leaves are oval to ovate, the petioles having two glands. The fragrant purple flowers are about two inches in diameter. The ovoid-pointed fruit has a tough, leathery shell which, when green, is six-striated, with white stripes; when quite ripe the fruit is a dull orange-yellow. The numerous seeds are imbedded in the juicy, scented pulp, which is aromatic and delicious. Propagation is by seed and by cuttings. [Illustration: PLATE CVI.--_Passiflora alata._ One half natural size.] _G. P. W. Collection._ PLATE CVII _Passiflora, var. foetida._ This strong and hardy vine grows well on arbors and trellises. Its leaves are three-cleft, and have long petioles; and spiral tendrils spring from the axils. The single, pale-green flowers are surrounded by a green, lace-like covering. The fruit is nearly globular, and slightly pointed; it is about three-fourths of an inch in diameter, and when ripe is a bright scarlet.

Although this plant with its wonderful nocturnal blossoms may be found growing almost everywhere in the Islands, the best specimens of its kind may be seen on the stone walls of Oahu College. The beautiful creamy flowers with their yellow centers are large, about a foot long, and when in full bloom about the same in diameter. The tube is covered with large, leaf-like green scales. The fruit, which is about 3½ inches long and 2 inches in diameter, is covered with persistent, large, fleshy scales which are scarlet colored when ripe, and the interior pulp is edible and refreshing. Fruit, however, upon the night-blooming cereus in Hawaii is rather rare, although a few fine specimens have matured.

This medium-sized and very handsome shade tree is a native of tropical Africa. It was probably introduced to Hawaii by Dr. Hillebrand. A fine tree of this species is growing in Mrs. Foster's garden, Nuuanu avenue. It has large pinnate leaves, and panicles of purple flowers. The peculiar rough, grey, oblong fruits hang from a long stem, and present an odd appearance. This tree and also one other of the same variety growing in the grounds of the Queen's Hospital, very rarely set their fruit. Because of the difficulty of obtaining seeds, the sausage tree has not been widely distributed. [Illustration: PLATE CIX.--_Sausage Tree._ One fourth natural size.] _G. P. W.
