Die Arbeit ist auch morphologisch und biologisch von Bedentung. Wichtig 

 hierfür sind folgende Punkte: 



1. Baccharis genistelloides is a plant remarkably well adapted by the loss 

 of leaves, by the position of the wings, and by the coverings of the cutin, 

 wax and hairs, to withstand a high degree of both dryness and insolation. 



2. The glandulär hairs differ from the hairs previously described in the 

 Compositae in the possession of Chlorophyll, and the whip-hairs in being biserial. 



3. The early acquisition of lignin in the hast of the stem. and of 

 mechanical tissue in thewings, gives to the plant its characteristic rigidity, 

 and at the same time necessitates a short period of elongation. 



4. The leaves found in any given portion of the stem on the older parts 

 of the plant resemble closely the leaves of other species of Baccharis- 



5. The leaf differs from the wing in structure in showing marked dorsi- 

 ventrality, which is absent in the latter. 



6. While the wings are directly continuous with the margins of the 

 scales and of the leaves when present, and while they follow the phyllotaxy, 

 they are to be considered morphologically as lateral-vertical expansions of the 

 stem and not as „decurrent leaves". 



7. The shoots have been shown to be markedly apogeotropic and positively 

 phototropic. 



8. Cuttings of growing shoots were made, a number of which after 

 rooting producod branches which bore reversionary leaves and greatly reduced 

 wings; the apices of the old shoots also produced in the leaves in two cases.
