Opuntia Missouriensis, Candolle. 
From Nebraska to New Mexico. Mr. Meehan found this Cactus 
covered with the Cochineal Coccus and points to the fact that 
this insect will live through the intense cold, which characterises 
the rocky mountains of the Colorado regions. 
Opuntia Rafinesquii, Engelmann. 
North America. The most northern of all species, extending to 
lake Michigan. 
Osmitopsis asteriscoides, Cassini. 
South Africa. A camphor-scented shrub, much in use there for 
medicinal purposes (Dr. Pappe). 
Oxalis esculenta, Otto and Dietrich. 
Mexico, there with 0. tetraphylla (Cavanilles), 0. Deppei 
(Loddiges), 0. violacea (Linne) and several others producing 
tuberous starchy wholesome roots ; the first mentioned gives 
the largest yield. As similarly useful may be mentioned among 
many others — O. crenata (Jacquin), from Chili, and 0. ennea- 
phylla (Cavanilles), from the Falkland Islands and Magelhaen’s 
Straits. 
Pachyma Hoelen, Fries. 
China. This large truffle occurs particularly in the province of 
Souchong. Flavour most agreeable. 
Panax papyrifer, F. v. Mueller. ( Arabia papyrifer , Hooker, Fatsia 
papyrifera, Bentham, Tetrapanax papyrifer, C. Koch). 
Island of Formosa. The Rice paper plant, hardy in the lowlands 
of Victoria, and of scenic effect in garden plantations ; the pith 
furnishes the material for the so-called rice-paper. 
Pappea Capensis, Ecklon and Zeyher. 
South Africa. The fruit of this tree is of the size of a cherry, 
savoury and edible. 
Fandanus fureatus, Roxburgh. 
This screw pine occurs in India up to heights of 4,000 feet, 
according to Mr. S. Kurz ; hence it will likely bear our clime, 
and give us a stately plant for scenic group-planting. P. pedunc- 
ulatus (R. Brown) occurs in East Australia as far south as 32nd 
degree, and the same or an allied tall species luxuriates in Howe’s 
Island. 
Pelargonium odoratissimum, Aiton. 
South Asia. A perennial trailing herb, from the leaves of which 
a fragrant oil can be distilled. The same remark applies to the 
shrubby P. Radula and P. capitatum (Dr. Rosenthal).
