4. P. Fairchildii Cheesem. 



A compact round-topped shrub 8 to 15 ft. high; leaves 2 to 3 in. long, 

 obovate to elliptic-oblong, broader than in no. 2, glabrous when mature, 

 the margins flat: capsule % to 1 in. long, becoming glabrous when half- 

 grown: otherwise like P. crassifolium. New Zealand. 



This species has not yet made its appearance here, but is 

 certain to be introduced from New Zealand, where it is grown 

 in gardens. More graceful and compact than P. crassifolium 

 and perhaps better suited to general planting. 



5. P. Tobira Ait. TOBIRA. JAPANESE PITTOSPORUM. 



A large spreading shrub with shining dark-green or variegated 

 foliage: bark gray: leaves 2 to 3% in. long, 1 to 1% in. wide, obovate 

 and very obtuse, gradually tapering to the short petiole, thick and 

 leathery, the margins recurved, perfectly glabrous: flowers in terminal 

 umbels, fragrant: corolla % in. long, white or rarely yellowish: capsule 

 % in. long, ovoid, 3- or 4-angled, densely short-hairy, tipped with the 

 persistent style. China and Japan. Var. variegatum Hort. has the leaves 

 (often thinner) variegated with white. Illustrations: Bot. Mag., pi. 

 1396; Nicholson, iii, fig. 193 (pot plant); Bailey, fig. 1837; Engler & 

 Prantl, Nat. Pfl., iii, 2a, fig. 62. 



Especially valuable because of its deep-green foliage and 

 abundant fragrant flowers, these latter resembling orange blos- 

 soms, both in appearance and odor. Suitable for lawns and 

 shrubberies rather than for hedges. Dr. Franceschi states that 

 it withstands violent saline winds better than most other shrubs 

 and is therefore adapted to seashore planting. 



6. P. viridiflorum Sims. P. sinense Desf. GREEN-FLOWERED 



PITTOSPOR,UM. 



Much like P. Tobira but becoming larger, more tree-like and with 

 smaller greenish and yellow flowers in dense compound clusters: ripe 

 capsule subglobose, * ' glabrous, as large as a pea, 2- to 6-seeded. ' ' South 

 Africa. Illustrations: Bot. Mag., pi. 1684; Nicholson, iii, fig. 194. 



Very rare as yet in California gardens but one of the best 

 of the larger Pittosporums. A magnificent specimen in Santa 

 Barbara, remarkable for its graceful habit and lively-green, 

 glossy foliage, is 25 feet high, the trunk 10 inches in diameter. 

 The very fragrant flowers are borne profusely during the winter 

 and spring months but the tree sets no fruits, perhaps owing to 

 the absence of pollen from other trees.
