TREES OF NORTH AMERICA 



colored puberulous pedicels from the axils of minute acute scarious bracts usually deciduous 

 before the opening of the flower-buds, from the axils of young leaves or on the branches of 

 the previous year from leafless nodes; calyx yellow-green, puberulous on the outer surface 

 and deeply divided into broad-ovate rounded lobes rather shorter than the oblong-ovate 

 rounded divisions of the light yellow corolla; staminodia lanceolate, nearly entire, tipped 

 with a subulate point and much shorter than the stamens: ovary oblong-ovoid, glabrous, 

 gradually contracted into an elongated style stigmatic at apex. Fruit ripening in March 

 and April on a much thickened woody stem erect or nearly at right angles to the branch, 1'

long, separating from the calyx in falling, with tough yellow skin, and thick juicy flesh of a 

 pleasant subacid flavor; seed obovoid, rounded above, narrowed at base, %' long and $' 

 wide. 



A tree, in Florida 60-70 high, with a massive straight trunk 3-4 in diameter, stout 

 upright branches forming a dense irregular head, and thick terete branchlets orange-colored 

 and slightly puberulous when they first appear, becoming glabrous, brown more or less 

 tinged with red, and marked by the conspicuous nearly orbicular leaf-scars displaying 3 

 large fibre-vascular bundle-scars, and conspicuously roughened by the thickened persistent 

 bases of the fruit stalks. Bark of the trunk \'-\' thick, dark gray to light brown tinged 

 with red and broken into thick plate-like scales separating into thin layers. Wood heavy, 

 hard, strong, bright orange-colored, with thick yellow sapwood of 40-50 layers of annual 

 growth; in Florida used in boat-building. 



Distribution. Florida, Cape Canaveral and Cape Romano to the southern keys; on the 

 Bahama Islands and many of the Antilles. 



2. DIPHOLIS A. DC. 



Trees or shrubs, with naked buds, and persistent leaves, the slender veins arcuate and 

 united near the margins. Flowers minute, on clavate ebracteolate pedicels from the axils 

 of minute deciduous bracts, in the axils of existing leaves or from the leafless nodes of previ- 

 ous years; calyx ovoid, deeply 5-lobed, the lobes nearly equal, ovate, rounded at apex; 

 corolla campanulate, white, 5-lobed, the spreading lobes furnished on each side at the base 

 with a linear or subulate appendage; stamens exserted; filaments filiform; anthers oblong- 

 sagittate, extrorse; staminodia 5, petaloid, ovate, acute, fimbriately cut on the margins, 

 oblique, keeled on the back, inserted in the same rank and alternate with the stamens; 

 ovary oblong or narrow-ovoid, gradually contracted into a slender style shorter than the 

 corolla and stigmatic at the apiculate apex. Fruit oblong-ovoid, with thin dry flesh.
