DR. M. T. MASTERS ON THE PASSIFLORACE E. 643 
belonging to the section Granadilla (see ante, p. 638, n. 176)—a section, as we have seen, 
having its head quarters in Brazil. 
Bourbon and Mauritius contain a form of Passiflora alata, by some considered di- 
stinct—a view I cannot assent to. T should deem it most probable that the species in 
question has been introduced from America at some period or another, and undergone a 
slight modification in course of time. 
In this brief review of the principal phenomena of geographical distribution of Passi- 
Jlorea I have hitherto omitted to speak of other tribes than the Passifloreæ and also of 
such species as Passiflora quadrangularis, which is cultivated in most parts of the tropics 
for the sake of its fruits, but which is probably of Central-American origin. Jacquin 
speaks of it as in cultivation in the West Indies, but not as wild. In Nicaragua, how- 
ever, it appears to be truly wild, and perhaps in Brazil also. P. fetida, in one or other 
of its varieties, is widely distributed throughout the tropical and subtropical regions of 
the globe. Perhaps its large sticky involucre has had something to do with its diffusion, 
burr-fashion, over so wide an area. Its medicinal or esculent qualities seem hardly 
sufficiently important to account for its wide dispersion. P. fetida and its varieties 
occur wild in the West Indies and Brazil. .P. suberosa and some of its varieties (var. 
minima for example) are also widely dispersed, one can hardly guess how or why; for 
there seems no special facility in its organization to account for its wide diffusion, and 
the plant has no prominent ornamental or useful qualities. "The head quarters of this 
species are in the West Indies; but forms of it are very abundant in Brazil The 
Galapagos forms have been previously alluded to. P. edulis, a Brazilian species, is also 
cultivated in the warmer parts of the world, and is likely to establish itself as a quasi- 
spontaneous plant in suitable localities. It has been found in Australia, probably as an 
escape from gardens (?).
