the bud is usually without eyes or hairs, and often raised 

 as a swelling. This is termed the cushion of the bud, and 

 is a marked feature of the Pansahi group, but absent in 

 the others which we are using as illustrations. 



Taking a dominant part in the shape of the bud are the 

 flanges. I have applied this term to scarious expansions 

 of the two lowest scales of the bud, seated as these are 

 on the right and le'ft sides, and completely covering the 

 other parts. The flanges may be extremely narrow, 

 hardly visible borders, or large auricled expansions; they 

 may rise near the top, in the middle, or at the lower part 

 of the bud; they may hardly project beyond the apex or 

 form a broad platform as big or bigger than the bud 

 itself; they may be rounded above so as to leave a deep 

 cleft between them or united to form a long beak-like 

 process. And these forms are usually more or less 

 constant for the variety, with the proviso that there are 

 minor variations in the different parts of the cane, as in 

 the bud itself. They may, lastly, be inconspicuous as to 

 colour, or dark and shining like the backs of beetles, 

 when they can be seen at a considerable distance. 



The vestiturc of hairs on the bud is of considerable 

 interest. I have divided the hairs into three main 

 classes : bristles, basal patches, and minute black hairs. 

 The former are confined to the flanges and add to the 

 variability of these parts; they are usually long and 

 straight, and generally determine whether the bud may 

 be called hairy or smooth. Their position and relative 

 abundance in different parts of the flanges appear to be 

 more or less definite. The basal patches clothe the lower 

 end of the bud on each side below the origin of the 

 flanges. Typically developed, they consist of a series, 

 on each side, of short, glistening, often curled hairs 

 arranged close together like the teeth of a comb. From 

 their position and appearance, I am inclined to regard 

 them as homologous with the circlet of hairs already 

 mentioned, and their presence or absence and their degree 

 of development generally differs in the different canes. 

 In some canes they are sharply circumscribed, while in 

 others they extend upwards on the veins irregularly, or 

 even pass along the edges, and become continuous with
