Mr. Schomburgk on the Snake-nut Tree. 203 



glandia* . All the buds which I opened consisted apparently 

 of 3 stamens and 1 pistil ; the calyx was imbricated, and this 

 might have induced me to consider it a Carya or Juglans ; but 

 the leaves of the tree in question are smooth and entire, while 

 those of the others, with the exception of two species, are 

 serrated. 



It is not a Carya, the nut of which is 4-angulated and 4- 

 valved, while the nut of Juglans, as well as the snake-nut, is 

 2-valved. I had requested Mr. Richardson to procure me 

 some of the flowers of the Snake-nut tree when perfectly open, 

 but he did not succeed in drying them, w^hich unfortunately 

 prevented him from sending any, and I am thus obliged to 

 wait for another opportunity of correctly describing this re- 

 markable plant. I offer the following description meanwhile 

 provisionally. 



Order. Terebinthace^e. 



Calyx imbricatus. Corolla 3-petala. Drupa bivalvis. 1-sperma. 



Vulg. Snake-nut tree.

 paniculag in ramulis terminales subinde axillares ; ramosse ; floribus 

 brevissime pedicellatis, numerosis confertis. Calyx imbricatus. Co-

 laris, glabra, sphaerica. Nux dura, glabra, bivalvis, unilocularis ; nucleo 

 albo. 



Hah. in sylvis Guiana? prope fluvium Essequibo. Floret Aprili. 



It is a tree of the first magnitude ; its bark is gray, rather 

 smooth, dividing in a few branches at a height of from 40 to 

 60 feet, adorned with pinnated leaves, consisting generally of 

 four to six pairs with an odd one ; the common foot- stalk as 

 well as the petioles are articulated, the former channeled; 

 the leaves entire, lanceolate, ovate, acuminate, lucid, coria- 

 ceous, their colour between light and dark green, with a 

 shade lighter below. The flowers appear in panicles, are 

 pendulous, and the flower-stalks of red-brown colour, almost 

 farinaceous, chiefly the smaller flower-stalks ; verticillate and 



* It stands perhaps between the Anacardice and Juglandice.
