different degrees of development of certain classes of buds and shoots in the 

 different classes. In Saccharum spontaneum and the Rogues from the thick 

 cane plots, it is the (h which form the bulk, these groups being closely followed 

 in this by the luxuriantly growing members of the Pansahi group. But 

 in the latter, the as are nearly as well developed, and this order of shoots is 

 dominant in the other groups, especially in the Nargori and Sunnabile forms. 

 This dominance of certain orders of branches is probably connected with the 

 formulae already discussed above, the tendency being in each case for the full 

 series of branches not to be symmetrical, but for the maximum to be thrown 

 forward, so that the higher members come beyond the middle of the series. 



Turning to the formulae in the odd lots, the six unclassified indigenous 

 canes, the Rogues and the Crosses between a thick cane and Sacclmrum sponta- 

 neum show certain peculiarities. The cane formula for the six unclassified 

 indigenous varieties is very short. This can be easily accounted for by an 

 examination of the varieties selected. They were not intended to be represent- 

 ative in any way, but were such as for one reason or another were interestino- 

 Thus the three Khelia, Khagri and Ilri, apparently closely related to one 

 another, showed a considerable likeness to the Thick canes, and Teboe Monjet 

 has a similar formula. Dhaulu of Phillaw approaches Sunnabile in its formula. 

 This was rather unexpected, as this form is considered, from other characters, 

 to be near the Mungo group, but its formula suggests the idea that it mav be 

 a connecting link between the Mungo and Sunnabile groups. Kassoer, a 

 strong-growing Java form, has the only extended formula, and resembles 

 Saretha in this. The average of the six cannot therefore be taken as represent- 

 ative of indigenous Indian canes generally, and they were not intended to be so. 



The Rogues show a very long formula and produce an immense number 

 of shoots of all kinds. This is in accordance with their great vigour and marked 

 primitive characters. The crosses of VelJoi by Saccharum spontaneum, on the other 

 hand, show sui-prisingly little influence of the male parent in their branchino-. 

 The formula is extremely short, practically that of Nargori and Sunnabile, 

 which groups are near to the Thick canes. This nearness to the Thick canes 

 is also shown in the richness of the juice in these two seedlings, which is not 

 in any way intermediate between the wild Saccharunis and Vellai.

It was noted above that, in judging the average length of the joints
