Plati/dcsma campanulata H. Mann. Proc. Bost. Soc. Nat. Hist., Vol. X, p. 317. 



A tree twenty-five or thirty feet in height, with a spreading crown, and a trunk eight or 

 ten inches in diameter, nearly glabrous ; the younger branches and leafy shoots of a light 

 color, or when quite young greenish, striped with narrow ridges and depressions, exhaling 

 a strong terebinthine odor when cut or bruised. Leaves varying in size on different parts 

 of the tree, from three to fourteen inches long, by one to four or five wide, lanceolate, or 

 more usually obovate-lanceolate, obtuse or acuminate, dark green above, and lighter 

 beneath, tapering at the base, of a not very thick coriaceous texture, pinnately veined (six 

 to eighteen pairs of veins) ; the veins divaricating after reaching about three fourths of the 

 distance to the margin, not uniting to form a distinct infra-marginal vein, and not strongly 

 reticulated ; the leaves very copiously punctate with innumerable small raised glandular 

 dots appearing black by reflected light; the petioles one half to two inches long. Pe- 

 duncles about equalling the petioles in length, bearing ovate-subulate bracts. Cyme three- 

 to five-flowered. Pedicels bracteolate, two or three lines long. Flowers hermaphrodite, nine 

 to ten lines long by six to seven lines in diameter, campanulate. Sepals four, four or five 

 lines long, decussatingly imbricated, the two outer longer and much thicker ones enclosing 

 the two inner in the bud, clothed with a minute sericeous pubescence extending down on 

 to the pedicels. Petals four, alternate with the sepals, in aestivation strongly imbricated or 

 often truly convolute, inserted under the disk, eight to nine lines long, obovate, thick and 

 fleshy, white, minutely sericeous, bearded on the margins, with the somewhat spreading and 

 recurved tips apiculate. Stamens eight, nearly as long as the petals, inserted on the margin 

 of the thin hypogynous disk ; the much dilated filaments monadelphous to the middle; the 

 sagittate introrsely dehiscent anthers wholly adnate to their interior face, and about two 

 lines long. Ovary globular, the four rounded-triangular carpels joined only by the central 

 columnar style, which is four times their length. Stigma terminal, entire, slightly four- 

 grooved. Ovules five in each cell, collateral and superposed, hemitropous. Fruit consisting 

 of four coriaceous, erect, distinct cocci, eight or nine lines long, and three or four in diam- 

 eter, lined with a hard, smooth, crustaceous endocarp, and half enclosed by the persistent 

 cup-shaped calyx ; usually ripening two seeds, which very much resemble those of Pclea. 

 The embryo was not seen. (Mann and Brigham, Coll. 94.) 



My friend and companion, Mr. W. T. Brigham, in crossing a dense thicket on the moun- 

 tains just above Honolulu, found a tree of much the size and appearance of this species, but 

 with much larger and more glabrous leaves, and much larger blossoms, nearly three quarters 

 of an inch in diameter; only one tree was seen, and unfortunately the specimens were 

 ruined in climbing out of the tangled mass of Frc/jcinctia, which was nearly impassable in the 

 rain and approaching darkness. Although we both twice returned as nearly as possible to the
