slightly narrow the way to the honey. After the male stage of 

 the flower is over, the filaments carry the anthers outside the 

 flower as in Rungia repens. At the close of the female stage of 

 flowering, the corolla falls, but there is still much honey on the

remaining parts to which visiting insects continue to go. Apis 

 dorsata was seen visiting in considerable numbers and appears 

 to be of the right kind of insect to effect fertilisation. 



HYMENOPTERA. Acqleata. Xylocopa aestuans, Lep., 

 Apis dorsata, P., and several similar bees. LEPIDOPTERA. 

 Rhopalocera. Several species. (Padoung, south of Prome, 

 24-ii-04). All at honey. 



Peristrophe bicalyculata, Nees. The butterfly Terias 

 has been seen visiting the flowers at Simulbasa in the Nepal 

 terai (27-xi-07). 



Vitex trifolia, Linn, f., has been seen to be visited by the 

 butterfly, Papilio polytes, for honey at Jamod, Berar (2o- 

 ix-09). At Tampin in the Malay Peninsula, a Xylocopa 

 visits it. 



Duranta Plumieri, Jacq. HYMENOPTERA. Aculeata. 

 4 species— LEPIDOPTERA. Rhopolocera. 2 species (Dam- 

 dim, Duars, 21-viii-07). 



Ocimum gratissimum, Linn., is fitted for the visits of bees, 

 but has ultimate self-pollination, for the stamens, which at 

 first diverge somewhat, laterally close together, and the stigma 

 is raised by the style to the anthers. The flowers were seen 

 to be visited by Apis indica at Pursua in the Nepal terai for 

 honey (28-xi-07). 



Plectranthus ternifolius. Don, has its stamens quite 

 hidden in the boat-shaped keel which visiting insects are 

 intended to depress. Although it is suited for the visits , of 

 small bees, butterflies only have been seen on it (Parsua, Nepal 

 terai, 22-xi-07). 



Plectranthus gerardianus, Benth. was seen to be visited 



Apis indica and several butterflies at Bhimpedi, 



Nepal (1 and 14-xii-07).
