PASSIFLORAS IN THE HAWAIIAN ISLANDS 367 



and purple in colour. The interior of the sepals and petals is often 

 distinctly carmine. The corona is nearly or quite as long as the 

 envelopes ; the numerous filaments are parti-coloured with red, 

 purple, and white bars. The fruit is ovoid and distinctly pointed, 

 with a tough, leathery shell. When green the rind has six light 

 stripes ; when thoroughly ripe it changes to a dull orange-yellow. 

 The pulp is juicy, aromatic, and deUcious in flavor ; this fruit is 

 one of the most edible of the entire group. The vine is very 

 handsome, and is often used for arbours and trellises ; there are 

 several fine specimens in Honolulu gardens. 



The familiar May-Pop of the Southern States, P. incarnata, is 

 also cultivated in Hawaii gardens. On the mainland United States 

 it occupies the region from Virginia south to Florida and west to 

 Missouri and Texas. It is a strong, tall-climbing vine, glabrous 

 or nearly so, and ascending to a height of ten to thirty feet. The 

 leaves are broadly cordate-ovate or nearly orbicular, and three- 

 lobed to about half their depth ; each lobe has two glands near 

 the base of the blade. The surface is glabrous or somewhat 

 pubescent ; the margin is finely serrate. The petiole is -|— 2 inches 

 long, with two glands near the summit. The flowers are axillary 

 and solitary, 1^-2 inches in diameter, white or purphsh. The 

 peduncles are longer than the petioles, and are usually three-bracted 

 just below the flower. The sepals are linear, cuspidate on the 

 back ; both sepals and petals are tinged with purple. The corona 

 is light purple, banded at its centre. The fruit is oblong or oval, 

 about 2 inches long, with three sutures; when ripe it turns yellow. 

 The name May-Pop refers to the month of ripening, in the South, 

 and the dry, inflated character of the fruit, which is scarcely edible. 

 In some places the vine is valued as ornamental, and is easily 

 grown from seed. 



The Blue Passion-Flower, P. cmrulea Linn., is a native of Brazil, 

 and the commonest species in American green-houses; it is grown 

 out-of-doors in the Southern States and Southern California, and 

 is not uncommon in the older gardens and estates of Hawaii. It is 

 a strong, slender grower, glabrous and somewhat glaucous. The 

 leaves are divided nearly to the petiole into five lanceolate or 

 lance-elliptic entire acuminate segments ; the top lower ones of 

 these are sometimes again lobed. The flowers are 3-4 inches in 

 diameter, and showy ; slightly fragrant, and greenish- white in 

 color. The coronal filaments are in two rows, blue at the apex, 

 white banded at the middle, and purple at the base. The styles 

 are light purple. The fruit is small and inedible. This species is 

 said to hybridize freely wdth many other Passifloras, and numerous 

 crosses, of minor horticultural importance, have been produced in 

 this way. 



The Scarlet Passion-Flow^er, P. coccinea Aubl. (Disema coccinea 

 in Hillebrand), is a South American vine that is comparatively 

 rare in the Hawaiian Islands. It is glabrous, with ovate, coarsely- 

 toothed leaves ; the petioles have two or three pairs of glands. 

 The flowers are bright scarlet, with an orange corona. The fruit 

 is edible, with juicy pulp; according to Bailey it is said to contain
