and sometimes emarginate at tip, finely reticulate; main nerve impressed above, 

 prominent beneath; veins salient on both faces; margin undulate. 



Flowers pedicellate, in glomerules of 18 or less, entirely glabrous. Pedicels 4 to 5 

 mm. long. Calyx about 1.5 mm. long; sepals suborbicular, shorter than broad. 

 Corolla pale yellow, 3.5 to 4 mm. long, 5-lobate; tube about 0.6 mm. long; lobes 

 ovate, obtuse, not auriculate. Staminodes ovate-acumi- 

 nate, 1.4 to 1.7 mm. long, with one or two subulate 

 points, irregularly denticulate on the margin, longitudi- 

 nally dotted-striate. Stamens short (1.8 to 2 mm. long); 

 filaments thick and straight, bent and subulate at tip; an- 

 thers ovate (1.6 to 1.8 mm. long) with the connective 

 cleft at the base and emarginate or shorter than the cells 

 at the tip. Pistil glabrous, about 2.3 mm. long at the 

 time of anthesis, deeply 5-sulcate; ovary ovate, 5-celled; 

 style short, obtuse. 



Fruit and seed unknown. 



Type in the U. S. National Herbarium, no. 268389, col- 

 lected at Izamal, Yucatan, July, 1895, by G. F. Gaumer 

 (no. 763). Tree 80 feet high, very rare, only one seen; 

 flowers. 



This species is a near relative of the forms with ovate 

 anthers of the West Indies and Florida, but differs from 

 them by its many-flowered clusters, the inauriculate 



lobes of its corollas, its emarginate connectives, its distinctly 5-sulcate pistils, and 

 probably by the characters of the fruit and seed. 



Sideroxylon tempisque Pittier, sp. nov. Plate 96, c. Figures 87, 88. 



A large tree. Branchlets more or less thick, with a dark gray bark, covered with 

 the verrucose scars of the fallen leaves. 



Leaves irregularly alternate, long-petiolate, glabrous, crowded at the ends of the 

 branchlets. Petioles 4 to 8 cm. long, canaliculate 

 above, rounded on the lower face, thicker and broader 

 at the base. Leaf blades 7 to 12 cm. long, 3 to 5 cm. 

 broad, elliptic-ovate, subacute at tip, finely reticulate, 

 wavy on the margin, extended at the base over the 

 petiole and forming a pouchlike, conical appendage, 

 this bearing almost always a single minute spine on the 

 upper margin; main nerve canaliculate above, prominent 

 below; primary veins slightly prominent on both faces. 

 Flowers pedicellate, yellowish white, in clusters of 10 

 or less in the defoliate axils nearest to the ends of the 

 branchlets. Pedicels about 5 mm. long, glabrous. Ca- 

 lyx about 3 mm. long, with 5 rounded ovate sepals, 

 pubescent outside, slightly adnate at the base, persist- 

 ent. Corolla 7 to 8 mm. long, 5-lobate, puberulous, 

 glabrescent outside; tube very short (not over 1.5 mm. 

 long); lobes imbricate, elliptic-ovate, 6 to 7 mm. long, 

 slightly concave, auriculate or subaurictilate at the 

 base, rounded at the apex. Staminodes rudimentary 

 (about 0.8 mm. long, ovate-squamiform, more or less 

 acute at tip. Stamens nearly as long as the lobes of the corolla, extrorse, glabrous; 

 filaments slender, rounded, 4 mm. long, subulate and incurved at tip; anthers 

 3.5 to 4 mm. long, extrorse, mediofix, ovate-acuminate, deeply cleft at the base, 

 obtuse at tip. Pistil about 5 mm. long at time of anthesis, claviform, minutely 

 hairy; ovary elongate-ovoid, 5-celled; style thick, obtuse.
