801. L. incurvus Roth. 



Visitors. Loew (Berlin) saw a humble-bee (Bombus agrorum F. ) pressin 

 the alae together normally, skg. and po-cltg. 



802. L. rotundifolius Willd. 



Visitors. Loew (Berlin) observed 2 bees : 1. Bombus agrorum F. 5, insertin 

 its proboscis laterally under the vexillum ; 2. Megachile fasciata Sm. S. skg.

232. Erythrina L. 



806. E. Crista-galli L. (Delpino, ' Ult. oss.,' pp. 64-8 ; Herm. Muller, ' We: 

 Beob./ II, p. 264.) The flower of this Brazilian species is twisted through an ang 

 of 180 , so that the large vexillum is directed downwards, and serves as s 

 alighting-place and platform for visitors. The stamens and style are enclosed t 

 the upwardly directed carina, the lower part of which is expanded into a necta 

 reservoir. The alae are only represented by two vestigial laminae. Cross-pollinatk 

 is favoured by the fact that the stigma projects a little beyond the anthers. 



Visitors. Delpino supposes that humming-birds are the pollinating agents. 



807. E. velutina. (Delpino, op. cit.) In this species the alae and carir 

 are reduced to minute vestiges, so that the column of sexual organs lies free und< 

 the vexillum. 



Visitors. Delpino believes these to be bees that must thrust in their hea< 

 between the sexual column and the vexillum to reach the nectar, which is secreted i 

 in papilionaceous flowers generally. 



2 33- Glycine L. 



808. G. chinensis Sims. (= Wistaria chinensis DC). The large blue flowe 

 of this species are associated in many-blossomed racemes. 



Visitors. Herm. Muller observed the following bees at Strasburg (' We 

 Beob.' II, p. 263). 



1. Anthidium manicatum L. &", skg.; 2. Anthophora personata ///. 5 and t>, do
