tor a jiarliciilar braiiL-li. From tlie upper branches the lelativu 

 position of the main and accessory buds ma}' be determined, and 

 t'roin this the main ur asilhuy nature of the branches situated 

 lower on the stem ascertained. 



Lastlv, a single instance has been found of a type in which 

 the plant appears to possess two sympodial branches arising 

 from the same leaf axil, one of which develops strongly, while the 

 second gives a single, or at most two, nodes bearing tlower buds. 

 This condition appears at Hist sight to constitute an exception 

 to the rule that the accessory bud gives rise to a nionopodium 

 onlv. At the base of the second, or dwarf, sympodium, on the 

 side removed from the main sympodium, occurs a small leaf or 

 bract, while between the two branches is found a bud. This 

 bract, therefore, constitutes the first leaf of a nionopodium 

 developed froni the accessory bud, and of which the first internodo 

 is reduced and the apical development arrested. The .sympodial 

 branch which apparently arises fiom the accessory bud is, tluL-^, 

 in reality, the tertiary branch aiising from the axil of the fir.st 

 leaf of a much reduced nionopodium. The same development 

 is found at many of tlie nodes of the secondary synipodial 

 branches, the accessory bud here giving rise to an apparent 

 sympodium (Plate VII). 



Further differences have been observed in the length and 

 thickness of the .sympodial branches. In the typical form the 

 iuternodes are relatively .short and the braiicli i.s of limited 

 growth. The branch thus formed is spreading or .slightly 

 ascending. In certain cases, however, there occurs a marked 

 development of secondary thickening. The branch in these 

 cases luse.'i the ' zig-zag ' habit described by Todaro and, owing 

 to the additional rigidity tlui.s obtaineil, becomes shaiply ascend- 

 ing. In f'eneral appearance the plant resembles the pure mono- 

 podial form found in India, from which, however, it is (juite 

 distinct. It has, moreover, a long vegetative period, for where 

 such secondary thickening occurs, the apical bud either fails to 

 develop entirely or withers after a rudimentary Hower bud has 

 been formed In other case.s the branches continue to develoji,
