that the twisting practically obliterates the lumen of the very 
thin-walled tube, there is no obstruction in the way to the honey. 
The outside of the corolla is hairy and below the twist is more or 
less protected against biting and robbing insects by the bracts (see 
fig. 6). The rectangular mouth of the tube is seen in fig. 8. 
The flowers open at dawn and fall on the same day between
