230 PHANEROGAMIA. 



Pittosporum glabrum, Hook. & Am. Bot. Beech. Voy. p. 110, vix Putterl. Pittosp. 



Hab. On the Kaala Mountains, and behind Honolulu, Oahu, Sand- 

 wich Islands. 



A tall shrub, or small tree, glabrous throughout, even the inflores- 

 cence. Leaves coriaceous, but mostly rather thin, scattered or approxi- 

 mate in false whorls, from 2 to 5 inches long, the widest part an inch 

 to an inch and a half in breadth, obovate-oblong, or oblanceolate, with 

 a tapering base, the apex either obtuse, rounded, or more or less acumi- 

 nate, very smooth even when young, of nearly the same hue both 

 sides, entire, inconspicuously veined : petioles from 6 to 12 lines long. 

 Peduncles terminal, or lateral (by the yearly growth of the branch), 

 and below the leaves, spreading or pendulous, glabrous, half an inch 

 or more in length, racemosely or corymbosely few- {5-6) -flowered at 

 the apex. Pedicels, 3 lines long. Calyx five-parted, very short, 1 i lines 

 in diameter, wholly glabrous; the segments broadly ovate, acute. 

 Corolla 6 lines long, apparently white : the petals linear-spatulate, 

 connivent, and at their upper part coalescent into a tube ; the dila- 

 ted and spreading tips about 2 lines in length. Filaments filiform, 3 

 or 4 lines long : anthers linear-sagittate, mucronate. Ovary entirely 

 glabrous, sessile, somewhat quadrangular, terminated by a columnar 

 style as long as itself; the stigma truncate. Capsule subglobose, but 

 somewhat compressed parallel with the two valves, glabrous, smooth, or 

 the surface minutely roughish, two-celled, many-seeded; the valves 

 coriaceous, not very thick, about an inch in length and 9 lines broad. 

 Seeds dark purple, closely packed in two rows in each cell, vertically 

 compressed, 2 or 3 lines in diameter; the testa smooth (Plate 19, Fig. 

 12), scarcely if at all shining. 



There are specimens in the collection, from the mountains behind 

 Honolulu (in fruit only) which, with the foliage and the smooth seeds 

 of P. glabrum, have thicker-walled and minutely tomentose pods, the 

 surface of which is more or less tubercular-roughened. These, with 

 some other specimens, seem to be intermediate between P. glabrum 

 and the following species, although the ordinary states of the 

 two would appear to be abundantly different. It remains to be 

 seen, however, whether the character taken from the seeds will prove 

 constant.
