Woods about the waterfall in the Happy Valley. To Dr. Gardner's 
description, quoted above, may be added:—Female plant, with the 
racemes fewer-flowered than in the male. Calyx and petals as in the 
male. Ovary pubescent, ovato-globose, on a crenated dise, and crowned 
byalong style. Stigmas short, acute. Ovary 2-celled, each cell with 
two pair of collateral ovules suspended by pairs from the central axis. 
Rudiments of stamens none. I find the stamens of the male flowers to 
be 8. I have not seen the fruit. This species grows to a much- 
branched under-tree ; the male plants, loaded with clusters of pea- - 
green flowers, are exceedingly attractive to bees: they blow in April.

(Continued from p. 239.) 
The Isthmus is rich in medicinal plants, many of which are only

Juss.), Corpachi (Croton pseudo-China, Cham. et Schlecht.), Guavito 
cmargo (Quassia amara, Linn.), Cedron (Simaba Cedron, Planch.), and 
- several Gentianeæ, also herbaceous plants, which are known to the in- 
habitants by the name of Canchalaguas, and which belong to the genera 
Eustoma, Coutoubea, and Schultesia. As purgatives are used, Ninno 
_ muerto, or Malcasada (Asclepias Curassavica, Linn.), Frijolillo (Cassia 
Occidentalis, Linn.), Cannafistola de purgar (Cassia Fistula, Linn.), Lau- 
_ renno (Cassia alata, Linn.), Savilla (Hura crepitans, Linn.), and Coguillo 
_ (Jatropha Curcas, Linn.). Emetics are obtained from Garriba de penna 
(Begonia sp.), and Frailecillo (Jatropha gossypifolia, Linn.). As vul- 
. meraries they use Chiriqui (Trivis frutescens, P. Br.), and Guazimillo, or 
. Palo del soldado. (Waltheria glomerata, Presl), and Cope chico de suelo 
(Arrudea clusioides, St. Hil.), Anti-syphilities are, Cardo santo (Arge- 
. mone Mexicana, Linn.), Zarzaparilla (Smilax sp. pl), and Oabeza del
