The inflorescence of the mango (Mangifera indica, L.) 
_ often becomes wholly or partly vegetative. The first sign of 
this vegetative character is the production of foliar bracts on 
the main axis. The flowers occurring on such an inflorescence 
interesting is that in which one side of the inflorescence is 
reproductive, while the other side is vegetative A case of 
this kind was recorded in the Journal and Proceedings of the 
Asiatic Society of Bengal, New Series, Vol. IIT, p. 427, in an 
article by Burkill and Bose, entitled ‘‘ An Abnormal Branch 
of the Mango.’’ This is, as far as we know, the only pub- 
lished record of such a phenomenon. It is not rare, however, 
and the present writers come across some examples every year. 
Burkill and Bose, after dealing with the phyllotaxy, devoted 
most of their attention to the correlation of external morpho- 
logy and internal structure, and showed that. in the case 
studied, the vascular tissue was thicker on the foliage side 
of the axis, and that this was mainly due to the greater develop- 
ment of the xylem. The vessels on that side were moreover 
wider, and bhiers was 2 greater soley aia of the wood-fibres. 
In the cases examined by us, the same characters have 
ninanie variation of the inflorescence. On February 6th, 1914, 
six inflores scences were enarched on to the top of one-year-old 
‘fcountry’’ stocks, one inflorescence to each stock. The 
scions were separated from the parent plants in the second week 
of May, 1914. The inflorescence grafts were photographed 
- on June 6th, 1914 (Plates VI, Fig. | and VII). Three of the
