and are consequently hexagonal, while the points are 

 very strong and sharp." It has five compartments or 

 cells filled with cream-eolored pulp in which are imbed- 

 ded two or three seeds the size of chestnuts. The liking 

 for the durian is an acquired taste. "To eat durians," 

 writes Wallucp, "is a new sensation, worth a voyage to 

 the East to experience." 



PHILLYRfiA (its ancient Greek name). Ole&cece. 

 Ornamental evergreen shrubs, with opposite short- 

 petioled, entire or serrate Ivs., small white, usually fra- 

 grant fls. in axillary clusters and small berry-like, 

 dark-colored fruit. Most species are hardy only South, 

 but P. decora^ the handsomest of all the species, is 

 probably hardy in sheltered positions as far north as 

 New York. The Phillyreas maybe used in the southern 

 states and Calif, for evergreen shrubberies in drier and 

 more exposed localities. They grow in almost any soil 

 and prefer sunny positions; P. decora alone seems to 

 grow better if partly shaded. Prop, by seeds and l)y 

 cuttings of half-ripened wood under glass in summer 

 or by layers; they are also sometimes grafted on Li- 

 gustrum ovalifolium. Five species in the Mediterranean 

 region. Lvs. entire or serrulate, thick and leathery, 

 quite glabrous: fls small, in axillary short racemes; 

 calyx 4-toothed; corolla 4-lohed, with short tube; sta- 

 mens 2, with very short filaments; style shorter than 

 tube: ovary 2-celied • fr a 1-seeded black drupe.

 of only one species.

Only a few Philodendrons can be grown to have an 

 ornamental appearance in a small state. One which 

 goes under the name of P. eleganlissimum, with finely 

 cut leaves, makes a good pot specimen, although it will 

 reach a good height where suitable opportunities are 

 aft'orded. The same may be said of P. Selloum, a beau- 

 tiful species with pinnatifld leaves. The arborescent 

 kinds should have a very porous rooting medium and 

 copious supplies of water while in active -lowili. \\ l.en

 unidentified trade name.
