the operculum rather flat or broadly convex; seeds 1 to 5 in each cell, about

Our only specimen, consisting of a 
branchlet with attached leaf and fruit, 
and supplemented by a few good pictures 
of the latter, was collected in the forests 
of the plains of San Carlos, northern 
Costa Rica, April 15, 1908, Cook & 
Doyle, ne. 95 (U.S. National Herbarium 
no. 473872). It is somewhat defective, 
ilthough sufficient to show that it does 
not correspond to the description of any 
of the species hitherto published. TFig- 
ure 1 has been somewhat schematically 
reconstructed from one of the photo- 
graphs, to show the mode of suspension of the seeds, characteristic of the genus.

Couroupita Aubl. Pl. Guian. 2: TOS. 1775. 
Calyx adnate, sepals small; petals rather large: androphorum with fertile 
stamens both on the ring or disk and on the helmet or galea; ovary 6-celled, 
stigma G-suleate; fruit large, globose, with a small, adhering operculum and 
containing from 80 to 40 small, ovoid, velvety-pubescent seeds embedded in a 
viscous, fetid pulp,—High trees, with a lofty, thick trunk and a flat or elongated 
crown; leaves oblong-elliptic; inflorescence racemose; flowers generally much 
larger than in the other genera of the same tribe.

* Leaves obtuse; margin of calyx lobulate,” petals obtuse: greatest diameter 
of flower 7.5 cm., the 6 petals obovate, obtuse, alternate, the 3 exterior slightly 
smaller, 2 to 3.5 em. long, 1.8 to 2.2 cm. broad; stamens very numerous upon 
both the disk and the galea, the anthers ovoid, 0.56 mm. long, 0.5 mm. broad, 
sessile upon dark appendages, these about 1 mm. long and distinctly claviform 
on the disk, a little longer, broad at base, 
and attenuate at tip on the galea.

Capt. John Donnell Smith under no, 5004, De Candolle observes that the flow- 
ers of this species are smaller than those of C. guianensis, which we find to be 
true, and that it differs, moreover, by the browaish white color of the same and 
the bluish pulp inside the fruit.
