144 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
mm. long and 13 to 14 mm. in diameter, covered outside with a thick, fugacious, ferru- 
ginous tomentum; pericarp 1.3 mm. thick. Aril deep pink, divided for about two- 
thirds of its length. Seeds 12 mm. long, 9 mm. in diameter, obovoid, pointed at the 
base; testa thin, grayish outside and sulcate. 
Type in the U. S, National Herbarium, nos. 678554-5, male flowers, collected in 
forests along the Chagres River above Alhajuela, Province of Panama, Panama, May 
12, 1911, by H. Pittier (no. 3505). 
Represented also by nos. 715464-6, imperfect female flowers and ripe fruit, col- 
lected in woods around San Felix, eastern Chiriquf, Panama, December 22, 1911, by 
H. Pittier (no. 5255). 
Virola warburgii belongs to the section Amblyanthera Warb. and stands between 
the Brazilian species V. carinaia and V. venosa. The seeds from Chiriqu{ mentioned 
by Dr. Warburg in the appendix to the description of V. panamensis! agree with those 
of this species. According to that monographer, the chalaza is very deep below the 
apex and forms an umbilical prominence, a scarcely impressed raphe extends to the 
hilum, and the ruminate endosperm contains fats and crystalloids but no starch. 
These details I could not verify. The common name of the tree is “bogamani,”’ and 
not “bogobane.’’ 
EXPLANATION OF PLATE 57.—Leaves and fruit; fruit after dehiscence and aril detached. Material from 
same tree as type specimen. All natural size. 
Compsoneura costaricensis Warb. Repert. Nov. Sp. Fedde 1: 71.1905. Pratr 58. 
A middle-sized tree with pyramidal crown. Branchlets glabrous, 2 to 4.5 mm. 
thick, brownish green. 
Leaves petiolate, large, membranous, quite glabrous, light green and lustrous above, 
paler beneath. Petioles 1 to 1.5 cm. long, broadly canaliculate. Leaf blades oblong, 
17 to 28 cm. long, 5 to 11 cm. broad, rounded and abruptly cuneate at the base, rounded 
and abruptly narrowed into an obtuse acumen at tip; margin slightly undulate. 
Costa and primary veins prominent below, the latter 9 to 12, arcuate, parallel, hardly 
confluent along the margin; minor veins transverse, almost parallel, distinctly promi- 
nent on both faces. 
Inflorescences axillary, often geminate, racemose, 1.5 to 3 cm. long, the branchlets 
2 to3 mm. thick; flowers few, clustered at the ends of the racemes (?), their characters 
not known. 
Fruit usually 1, sometimes 2 or 3, in each raceme, ovate, 2.5 to 3.2 cm. long, 
2 cm. in diameter, borne on a slender pedicel 7 mm. long, the pericarp yellowish 
green, smooth. Aril pale yellow, continuous and completely wrapping the seed 
except at the apex, there open and short-lobate. Perisperm lignose, the surface 
smooth, pinkish gray with dark brown lines and irregular elongate spots radiating 
from the basal hilum; endosperm hard, white, hardly ruminate. Embryo small, 
basal.

The above is an emended translation of Dr. Warburg’s original description. Notes 
taken by me on the occasion when Mr. Tonduz collected his specimens, indicate a 
middle-sized tree with a habit like that of Virola. The leaves are much larger than 
stated by Dr. Warburg and. judging from the fruit-bearing rachis in our specimens, 
the racemes are flowered from the base (what I take for remnants of pedicels may, 
however, be aborted branchlets). The pedicellate nuts attain a length of 3.2 cm. 
The locality where Koschny collected is given as San José, whereas it should read 
San Carlos; further, the text, after the description of the aril should read “‘perispermo ”
