dilated so that access to the honey from the inner side is impos- 

 sible. They, as well as the inner surface of the corolla, are also 

 densely clothed with soft woolly slanting hairs, as a protection 

 against small insects and the wet. 



Each anther is tipped by four unequal elastic awns. The two 

 outer processes are shorter and stand obliquely, obstructing the 

 path between the anthers. The terminal awns also diverge, 

 affording a triangular passage for the proboscis of the bee. The 

 tubes are recurved and turn inward slightly, bringing the pores 

 directly at the end, partially facing each other, whereas, in Gay- 

 lussaaa resinosa, the pores face the style. As the proboscis of 

 the insect passes over these openings it is necessarily brought in 

 contact with the pollen. Exteriorly the anther tubes are covered 

 with a soft, white, farinaceous powder much finer than the pollen 



grains, which probably serves to protect the sensitive tongue of 

 the bee. 



The aromatic scented flowers are white with reddish calyx and 

 pedicels. Unsuccessful attempts of bees to puncture the corolla 

 with the mandibles are indicated by double crescent-shaped marks.

Cheloxe glabra L. Turtle-head. 



The English name is due to the form and general reptilian ap- 

 pearance of the flower. The corolla is 25 mm. long, sessile, and 

 firmly held by the imbricated sepals and concave bracts. The 

 u PPer lip posteriorly is broad and inflated, affording ample room 

 f °r the body of the bee, which enters entirely within the corolla. 

 * °ee, which found difficulty in retreating from getting astride the 

 filaments, was observed to turn completely around. In front the 

 SlcJ es of the upper lip are flattened and bend slightly inward to 

 form a keel within which lies the style. The apex is notched with 

 the extreme margins recurved to afford easier ingress. 



•Midway in the lower lip there is a reentrant fold, or concavity, 

 which greatly narrows the entrance and from its elasticity causes 

 the corolla to resume its original shape after the visit of an insect.
