 Passiflora quadrangularis, L. 



Brazil. One of the most commonly cultivated G-rana- 

 dillas. 



Passiflora serrata, L. 



From West India to Brazil. 



Passiflora suberosa, L. (P. pallida, L.) 



From Florida to Brazil. A careful investigator, Dr. Maxw. 

 Masters, has recently defined about 200 species of Passion- 

 flowers. 



Peireskia aculeata, 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, Humb., 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, Rich.* 



(Penicillaria spicata, Willd. Panicum coeruleum, 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. Sorre 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. Several other species occur 

 in South Africa.
