TWO NEW SPECIES OF CALOPHYLLUM FROM MEXICO. 
The genus Calophyllum of Linnaeus is composed of about 50 spe- 
cies, natives chiefly of tropical Asia and Africa. Vesque, in his 
monograph of the genus,? reports only four species from the Western 
Hemisphere: (. calaba Jacq., of the West Indies; C. brasiliense 
Camb., ranging from Brazil to Panama; C. lucidwm Benth., of the 
Guianas; and C. pachyphyllum Triana & Planch., of Brazil. The 
recent discovery of two species in southern Mexico indicates that 
the range of the genus extends farther north than had been believed 
previously. 
Calophyllum rekoi Standl., sp. nov. 
Tree, 20 to 25 meters high, the branchlets stout, angulate and plicate-striate, 
pruinose-puberulent at first but soon glabrate, the internodes elongate; petioles 
stout, 2.2 to 3.2 cm. long, sulcate on the upper side, rounded beneath; leaf 
blades elliptic or narrowly elliptic-oblong, 10.5 to 16 cm. long, 4.3 to 6 cm. wide, 
obtuse or acute at the base, acutish or obtusely short-acuminate at the apex, 
coriaceous, lustrous above, the costa impressed near the base, prominent toward 
the apex, dull beneath, the costa salient, the lateral nerves very numerous, 
approximate, parallel, prominulous, the margin thickened; racemes axillary, 
mostly 7-flowered, 2.5 to 3.5 cm. long, short-pedunculate, the rachis and pedicels 
puberulent, the latter stout, 2.5 to 5 mm. long; bracts minute, caducous; polyga- 
mous flowers 8 mm. broad, the sepals 4, reflexed, oval, more or less cucullate, 
the 2 inner ones petaloid, the petals wanting; stamens 7 to 12, the anthers 
1.5 to 2 mm. long; ovary globose, the stigma peltate, irregularly lobed. 
Type in the U. 8. National Herbarium, no 842605, collected at Cafetal Con- 
cordia (Cerro Hspino), Oaxaca, Mexico, November 18, 1917, by B. P. Reko 
(no. 3557). 
This species is related to C. brasiliense, but is distinguished by the long 
petioles (twice as long as the latter species) and by the puberulent inflorescence. 
The vernacular names are given as “cimarr6n” and “cedro cimarrén.” 
Doctor Reko furnishes the following additional notes regarding the plant: 
“A most beautiful tree, about 20 to 25 meters high, growing very commonly 
here in nearly all the cafetales, at an altitude of about 600 to 800 meters, and 
highly appreciated on account of its excellent wood, which resembles mahogany. 
It is hardly possible to believe that such a tree should still be unknown in 
Mexico, and only the great difficulty in discovering the small, white flowers so 
high up in the foliage of the tree would account for it. The tree, when cut, 
produces a yellow, sticky sap, something similar to the ‘ chicle,’ and is used as 
‘leche Marfa’ by the Indians. The flowers are very fragrant. The fruit is 
spheric, of the size of a walnut (4 to 5 cm.).” 
Calophyllum chiapense Standl., sp. nov. 
Branches thick, grayish, the branchlets very stout, pruinose-puberulent at 
first but soon glabrate, densely leafy; petioles stout, 8 to 10 mm. long, sulcate 
on the upper surface, rounded beneath; leaf blades elliptic or obovate-elliptic, 
6.5 to 8.5 cm. long, 2.2 to 4 cm. wide, acute or cuneate at the base, obtuse or 
acutish at the apex, coriaceous, glabrous, lustrous above, the costa suleate near 
the base, prominulous toward the apex, the lateral nerves very numerous,
