Passiflora quadrangularis, L. 
Brazil. One of the most commonly cultivated Grana- 
dillas. 
Passiflora serrata, L. 
Prom West India to Brazil. 
Passiflora suberosa, B- (-P. pallida, L.) 
From Florida to Brazil. A careful investigator, Dr. Maxw. 
Masters, has recently defined about 200 species of Passion- 
flowers. 
Peireskia acaleata, Miller. 
West India. The Barbadoes Gooseberry. A tall shrub, 
adapted for hedges in localities free of frost. The Cochineal 
Insect can be reared also on this plant. The berries are 
edible. Several other species exist in tropical America, 
among which P. Bleo, Dumb., is particularly handsome, but 
they may not all be sufficiently hardy for utilitarian purposes 
in our clime. Otherwise the Bleo is used for salad. 
Peireskia portulacifolia, Haw. 
West India. This attains the size of a fair tree. 
Pennisetum thyphoideum, Eich.* 
{Benicillaria spicata, Willd. Panicum coeruleim, Miller.) 
Tropical Asia, Nubia and Egypt. The Bajree. An annual, 
ripening its millet crop in about three months in warm 
countries. The stems are thick and reach a height of 6 feet. 
This grass requires a rich and loose soil, and on such it will 
yield upwards of a hundred fold. It furnishes also a good 
hay, and is also valuable as green-fodder. Sone of the 
many other species of Pennisetum are doubtless of pastoral 
value. A plant allied to P. thyphoideum occurs in China : 
nameiy P. cereale, Trin. This affords also millets or corn 
for cakes. 
Pentzia virgata, Lessing, 
South Africa. A small bush, recommended to be established 
in our deserts for sheep -fodder. Heveral other species occur 
in South Africa.
