With the exception of a few Malayan and Chinese 

 species, the true Passifloras are natives of tropical 

 America. Many of them are cultivated as curiosities, 

 and some of them for the beauty of their flowers and 

 for their festooning foliage. The leaves are either digi- 

 tately lobed or angled or perfectly entire. The large, 

 showy flowers are solitary in the axils or on axillary 

 racemes. The fruit is oblong or globular and usually 

 fleshy or berry-like, .S-carpeled but 1-loculed, the seeds 

 being borne on parietal placentae. The fruit is allied to 

 the pepo of the Cvicurbitacese. The ovary is supported 

 on a long stalk which is inclosed in or usually united 

 with the tube formed by the union of the bases of the 

 filaments. The structure of the fruit is well shown in 

 Pig. 1650; the remains of the fioral envelopes have 

 broken from the attachment on the torus and rest on 

 the fruit. The petals are borne on the throat of the 

 calyx, but in some species they are absent. Nearly or 

 quite a dozen Passifloras are native to the U. S., and 

 one of them, P. Intea, grows naturally as far north 

 as southern Pa. and Illinois. From Virginia south, the 

 Maypop, P. incarnuta, is a very common plant in fields 

 and waste places. Both these species are herbaceous 

 perennials. The fruit of some Passifloras is edible. 



In cultivation, the Passifloras have been considerably 

 hybridized, and they are also confused with Tacsonia. 

 In 1871 Masters enumerated 184 species (Trans. Linn. 

 Soc. 26), and a number of species have been discovered 

 since that time. 



PASSIFLORA 



Most of the Passion-flowers are yellow or green in 

 color of envelopes, but there are fine reds in P. rai-f-- 

 mosa, P. Baddiana, P. coccinea, P. alatu, P. vitifoliu, 

 and two or three others. l H. B. 



P. carulea and Constance Elliott are both hardy at 

 Washington. In summer time we use P. faetida (raised 

 from seed annually), and during the last two seasons, 

 P. Uolimensis, for trellis work. The last named is a 

 good thing for this line of work ; the fls. are white, 

 purple center, about 2 in. in diameter; native of Mexico; 

 very easy to prop, from cuttings of soft wood. Not many 

 of the tender species and hybrids are grown to any great 

 extent in this country. P. alata and P. quadnriKjiihiris 

 are desirable climbers for a roomy, warm greenhouse. 

 P. quadrangularis, var. ancubifo'lia, seems to flower 

 quite as freely as the green-leaved one. Passifloras 

 are prop, from cuttings of the half-ripened growth, with 

 bottom heat. P. racemosa and P. lyoudoni are a trifle 

 difficult to root from cuttings; the growths should be as 

 ripe as possible for this purpose. Keep the under sur- 

 face of the leaves flat on the sand while rooting. The 

 native P. im-iirnutd grows very freely at Washington, 

 becoming more or less of a weed and hard to eradicate.
