it especially valuable where something is needed to relieve the 

 somber appearance of our ordinary dark-green shrubbery. 

 When grown for hedges the plants should be set not more than 

 three feet apart and the lateral branches clipped back occa- 

 sionally; in a few years it may be trimmed to a narrow hedge. 

 The fragrance, said to be very noticeable in wild trees, seems 

 to be lost in cultivation. "The wood is white, tough, elastic, 

 and of considerable strength, but soon perishes when exposed. 

 It is frequently used by the wood-turner" (Kirk). 



10. P. heterophyllum Franch. 



A low, half-reclining shrub or low hedge plant with light-green foli- 

 age: leaves 1 or 2 in. long, % to 1 in. broad, lance-shaped or ovate, 

 tapering to both ends but nearly sessile, entire, glabrous: flowers few in 

 simple clusters terminating short branchlets, the peduncles only very 

 rarely divided: corolla light yellow, about ^ in. long: capsule barely 

 % in. long, globose, minutely pubescent when half-grown, glabrous at 

 maturity. Western China. 



Introduced by Dr. Franceschi in 1908, his specimens with 

 small ovate leaves. In China the leaves are extremely variable 

 in size and shape, even on the same branch. Dr. Franceschi 

 recommends it for large rockeries and embankments, and states 

 that it is drought resistant. 



11. P. rhombifolium A. Cunn. QUEENSLAND PITTOSPORUM. 



A tree of pryamidal growth, said to reach 60 to 80 ft. in height: 

 leaves 3 to 4 in. long, 1 or 2 in. wide, rhomboid, being broadest in the 

 middle and tapering to each end, acuminate, coarsely and irregularly 

 toothed, glabrous: flowers numerous in a wide compound terminal cluster: 

 sepals rather obtuse, about one-half as long as the corolla, this y 8 to ^4 

 in. long and white: capsule berry-like, % in. long, nearly globose, tipped 

 by the persistent style and rounded to a short-columnar base, passing 

 from green through lemon color to bright orange-yellow, glabrous. Aus- 

 tralia. Illustration: Hooker, Icon., pi. 621. 



Little known in California but one of the very best sorts. 

 Sometimes grown as a pot plant, in which case it remains small, 

 and serviceable when young as a shrub, since it flowers when 

 only 5 or 6 feet high, but most valuable for avenue planting and 

 as a specimen tree for lawns and yards. Its central shaft gives 

 it an erect habit, the foliage is clean and thrifty, the flowers not 

 very showy and rather faintly odorous, the bright-yellow berries
