38 FLORA OF TASMANIA. [Pittosporea. 
tory at Recherche Bay. B. longiflora is a very variable plant, and this may be only a variety of it." The latter 
remark implies that the specimens were gathered close to where Labillardiere gathered his B. longiflora. To me the 
species seems very distinct, in the very long (1-|— If- inch) flowers, broad large sepals, long very blunt petals, and 
pubescent ovaries, which would apparently become lengthened into cylindrical berries; the ovary is also more 
distinctly two-celled than in B. longiflora.

Sepala 5. Petala 5, in tubum conniventia, apicibus recurvis. Stamina 5. Ovarium 2-5-loculare. 
Ovula plurima, semiseptorum marginibus inserta. Capsula compressa, incomplete 2-5-locularis j valvis 
lignosis v. eoriaceis. Semina plurima v. pauca, majuscula, in globum ope pulpo resinoso pleramque con- 
globata. Embryo minimus, in albumine duro. — Frutices v. arbores plerumque erecti, ramosij foliis persis- 
tentibus eoriaceis. 
The maximum of this genus will probably be found to be in the Pacific Islands ; upwards of a dozen Australian 
species are known, and there are ten in New Zealand ; all form shrubs or trees, with alternate, generally coriaceous 
leaves.— Flowers pedunculated, solitary or fascicled or corymbose. Sepals five. Petals five, deciduous, forming 
a campanulate corolla. Stamens five. Ovary two- to five-celled, with numerous ovules. Fruit a dry, woody, 
generally two-valved, two-celled capsule. Seeds numerous, angular, imbedded in a viscous gum exuded from the 
walls of the valves. Embryo minute, in horny albumen. (Name from Trirra, pitch, and enropos, a seed; in allusion 
to the gummy secretion surrounding the seeds.)

Hab. Throughout the Island, abundant in damp ravines, ascending to 4000 feet, Cunningham, etc. —

DisTMB. South-eastern Australia. 
One of the most variable plants in the Island, forming, in low grounds, a tree 30-40 feet high, with a trunk 
a foot and more in diameter, but gradually becoming a stunted scrubby bush on ascending the mountains. The 
changes of habit and characters on ascending are so gradual that I cannot rigidly define the varieties, of which the fol- 
lowing are the best marked : — on low ground, branches lax, twiggy, with spreading, fiat, linear-obovate or oblong 
leaves, 1J-2 inches long, with slightly revolute margins and silvery-grey down beneath : on ascending, the branches 
become short, rigid, robust, erect, leaves densely crowded, erect, shorter, blunter, rigidly coriaceous, margins very 
revolute, clothed below with ferruginous silky and villous hairs.— Flowers in corymbs, with slender, nodding pedun- 
cles, 1 inch long, in low situations ; solitary, or few together, with short rigid peduncles, in alpine places. Peduncles 
more or less villous. Sepals ovate, acute. Petals nearly £ inch long, yellow or reddish, with recurved apices. 
Capsules nearly globose, i~i inch across, two-valved, two-celled. Seeds about ten in each valve, imbedded in a 
red pulp.
