ON A NEW SPECIES OF CALYCOPHYLLUM. 623 
venosa, venulis ultimis translucidis. Petioli 2-4 lin. longi; 
stipule utrinque solitaria, integre, subconnate, ovato-lan- 
ceolatze, acutissime, fuscescentes, circa 2 lin. longe, decidue. 
Racemi terminales v. in axillis supremis axillares, 3-6 poll. 
longi, stricte erecti, simplices, v. utrinque ramo aucti, a 
medio ad apicem floriferi, tenuissime tomentosi, puberuli, 
pedunculo ancipiti, rachi angulata. Flores sessiles, sparsi, 
solitarii, v. per 2-3 congesti, singuli bractea parva squame- 
formi subtensi. Bractee 1-2, inferiores cujusve racemi et 
lobus alter calycum 1-2 inferiorum sepius expanse in lami- 
nam roseam 1-142 pollicarem, obovato-orbiculatam, obtusam, 
basi rotundato-cuneatam, petiolatam, ad venas puberulam. 
Calyces 2 lin. longi, tomentosi. Corolla extus pubescens, 
tubo 3 lin. longo, limbo expanso, laciniis latis obtusis. 
Stylus vix apice brevissime emarginato-bifidus. Stamina et 
ovarium omnino Calycophylli. 
The wood of the tree is very hard and of a yellowish- 
brown colour, and like others of the tribe Cinchonea, is of a 
strong bitter, so that I have little doubt it possesses febri- 
fugal properties. The Macusi Indians call the tree Dehpé ; 
I have only found it near the Rivers Rupununi and Takutu 
in the 3rd parallel of north latitude. 
It is worthy of remark that the bract-like leaf of the calyx 
enly forms itself after the flower has dropped off. This is 
the reason why only the lower parts of the racemes are 
adorned with them. The growth of the calycal leaf is very 
rapid, expanding to its natural size in the course of a couple 
of days,
