almost so. Ovary sessile, suborbicular, depressed, hairy, 2-ovulate; style fili- 
' form, geniculate close to the apex, hairy on the lower two-thirds of its length; 
stigma discoid, inconspicuous. 
Calyx very much enlarged after flowering, the tube about 2.5 mm. long, hairy 
and covered with large black glands without, the lobes membranous, ovate- 
elliptic or obovate, hairy without, 3-nerved, beautifully reticulate, sparsely 
glandular, 8 to 9.5 mm. long (the carinal one shortest), 2.5 to 3.5 mm. broad. 
Type in the U. S. National Herbarium, no. 602365, collected in Quebrada del 
Tigre, State of Lara, Venezuela, in bud and immature fruit, September 6, 1910, 
by Dr. A. Jahn (no, 173). 
Until recently Apoplanesia was known to botanists only by a single obscure 
species from Mexico. The discovery by Dr. Jahn of a new member of the genus 
in Venezuela is therefore highly interesting. It will be 
noticed, however, that the new species differs from the 
generic type in having a 2-ovulate ovary, which will 
necessitate a slight change in the characterization of the 
; group. In all the other characters the agreement is

ealyx lobes fully developed, while the upper two-thirds 
of the rachis is covered with very young buds. In the more advanced among 
these, the 5 petals are present, though imperfectly developed, but it was not 
possible to find them in any of the open flowers, in which the stamens with full 
anthers and the ovary scarcely turning into fruit were always present, 
It is also a remarkable coincidence that the Mexican and Venezuelan species 
should be known under the same name of “ palo de arco,” or bow-wood.
