signifies Tobacco iu the Arowak dialect. Some of the leaflets- 

 are marked with small, whitish, round spots. 



Flowers, numerous, borne towards the extreme part of long 

 spikes or racemes, which are both terminal and axillary. Bracteas, 

 lanceolate, acute, in pairs. The flowers also have a peculiar, 

 not the most pleasant, odour. 



Calyx, monopetalous, bell-shaped, five cleft, hairy, rough, 

 inferior, and persistent ; green, about one fourth of the length 

 of the Corolla. 



Corolla, somewhat curved prior to expansion, tubular, burst- 

 ing from the centre ; nearly an inch long ; tomentose both 

 inside and out ; composed of five unequal petals, two of them 

 being about l-9th longer and larger than the others, so united at 

 the base as to appear inseparable,* and indeed never separating ; 

 these petals are reflex, oblong, obtuse, fixed in the receptacle, 

 and, when faded, breaking off round the germ, leaving a pro- 

 tecting border besides the receptacle. 



Nectaria, if tbey may be called so, five linear leaflets borne 

 at the mouth of the tube, half the length of the petals, each 

 bearing at its summit a very minute, round, pellucid glandule, 

 filled with a fluid. 



Stamina, two. Before the expansion of the flower they are 

 found lying towards the inner or inflected side of the corolla, 

 the anthers in the groove of the two longer petals, the tips of the 

 three shorter ones being incurved over them as for protection. 

 Filaments flat, inserted into the two longer petals at the mouth of 

 the tube, considerably shorter than the nectaria. Anthers large, 

 linear, erect, longer than the filaments, four channelled, two 

 celled. 



Pistillum, consists of a five-lobed depressed germ, immersed 

 within a coriaceous receptacle ; a simple, filiform style, hairy at 

 the middle, longer than the tube, and a capitate entire stigma. 



Pericarp, consists of 5 bivalve capsules, of which 2 or 3 are 



• I had previously described the Corolla as monopetalous, and I still consider 

 it to be so, although, in submission to higher authorities, I have in the test 

 spoken of it as a pentapetolus Corolla.
