ventrali-lateral stamens are invariably smallest. These two stamens 

 cohere to the adjascent dorsi-lateral stamens by the basal portion of 

 filament. Then, the petals or nectaries intersticed between two stamens 

 of each lateral set disappear and the flowers with four stamens appear. 

 Next, the disappearance of dorsal stamen follows. Previous to this, 

 the union of two dorsal nectaries takes place and they become single 

 before or after the disappearance of dorsal stamen. This fused nectary 

 is 2n and will remain longer. Thus, the flower with 3 stamens and 

 3 nectaries is resulted. After this stage, the union of 2 ventral 

 nectaries begins and forms ordinary male flowers of Salix triandra. 

 From the pentamerous flowers, the triandrous flowers are formed 

 directly by the union of two lateral stamens on both sides and by the 

 evanescence of lateral glands which intersticed between two lateral 

 stamens. Now, the ventral stamen (this is often situated dorsally by 

 the farther union of the base of filament to the scale) degenerates 

 and disappear, and the most common distemon of Safe-flowers will 

 appear. As the two dorsal nectaries fused earlier than the two ventral 

 nectaries they do not remain longer and naturally will disappear first, 

 and in consequence, the distemonate flower with one gland is thus 

 formed. Farther more, the adherence of the two lateral stamens 

 begins and at last they unite completely as seen in Sections Gracilistylce 

 and Helix. In this case, the two united stamens are in same size, 

 hence the anthers united dorsally become four-celled, and the filament 

 has two vascular bundles distinctly in parallel. 



The writer presumes that he has explained sufficiently to prove how 

 Chosenia is distinct from Popidus and Salix, and how the degeneration 

 of floral parts of Salix took place in succession. Salicales is not an 

 order so primitive as arranged at present, but is far more advanced 

 and to be nearer to Ranales and Rhoeadales. In fact, Salicacece is an 

 interesting family with so many types in one genus. Polyandrous 

 Salices like Popidi have always shining leaves (e.g. Salix pentandra, 

 S. glandidosa etc.). When the leaves are persistent they are shining 

 (e.g. Salix berberifolia). Salicacece should not be only exceptioned
