or slightly acuminate, minutely glandulose dentate, 2'- 4' long, petioled. 

 Racemes axillary, about G-flovvered, bracted, pedicels 6"- 8" long, 2- 

 bracted below the middle. Sepals 4, rounded or oblong, obtuse or 

 barely pointed, glabrous, with the margin ciliated. Hypogynous disk 

 glandular. Stamens many, about 4 times as long as the sepals. Berry

ORDER VIII. PITTOSPORACE^. 



Trees or shrubs, with alternate and entire coriaceous leaves, differ- 

 ing from the shrubby Violacea; in having no stipules, perfectly regular 

 flowers, and a minute embryo in hard albumen : represented by the 

 chiefly Polynesian genus. 



1. PITTOSPORUM Banks. [Aawa.] 



Sepals 5. Petals 5, their claws erect and usually cohering into a 

 tube. Filaments subulate; anthers erect. Ovary sessile or shortly 

 stipitate on a more or less developed torus, imperfectly or nearly per- 

 fectly 2- (rarely 3 -5-) celled. Capsule ovate or obovate, often flat- 

 tened. Valves coriaceous or woody, bearing the placenta on their 

 middle. Seeds smooth or reticulated, usually covered with a resin. 

 Shrubs or trees, usually evergreen. Leaves in some species much 

 clustered at the ends of the branches. Flowers in a terminal corymb., 

 or few or solitary, or often clustered in the axils. 



A considerable genus, chiefly Australian and Polynesian, with a few tropical and sub- 

 tropical African and Asiatic species. 



Flowers in a terminal umbel : calyx large and very woolly, . . . . 1. P. confertiflorum. 

 Flowers fascicled In the axils, or below the leaves on the naked 



branches: peduncles almost none. 

 Calyx and ovary more or less tomentose or pubescent. 



Leaves thick coriaceous: style thrice shorter than the ovary, 



with a two-lobed stigma, 2. P. cauliftorum. 



Leaves thick-coriaceous: style as long as the ovary, with a 



terminal simple stigma, 3. P. terminalioides. 



Leaves thin-coriaceous: style as long as the ovary, with a 



capitate stigma, . . . . 4. P. spathulatum. 



Calyx and ovary (as is the whole plant) glabrous, . . . . 5. P. glabrum. 

 Flowers on long peduncles and pedicels, 6. P. acuminatum. 



1. P. CONFERTIFLORUM Gray. (Emim. No. 17.) Tree 20 high. 

 Branches stout, leafy, woolly when young. Leaves coriaceous, crowded 

 obovate or obovate-oblong, obtuse or short acuminate, 3'- 7' long, 1'- 

 2i' wide, the young ones woolly on both sides, the older ones very 

 glabrous and shining above, densely tomentose beneath ; margins revo- 

 lute. Petiole margined, 1' or less long. Flowers numerous and
