Helenioideae, Anthemideae and Senecionidese, the style-branches 

 begin to separate from the apex while in those of the Asteroidese 

 examined, they begin to separate from below the apex, forming 

 a more or less distinct loop which disappears upon complete 

 separation. The former might conveniently be termed Apici and 

 the latter Sub-Apici. 



In the determination of a Composite one is, at the outset, 

 confronted with a distinction of the style-branches and append- 

 ages which is b}^ no means clear, but the difficulty will be 

 greatly simplified if it is found that the sub-apicial separation of 

 the style-branches is peculiar to and constant in the Asteroidese- 

 I therefore venture to examined with a few brief notes: — 



SUB-APICI 



Tribe III. Asteroideae 



Aster. Cultivated species probably A. Novae Anglise 



Bigelovia veneta 



Erigeron foliosus var. stenophyllus 



Gutierrezia Euthamiae 



Heterotheca floribunda 

 APICI 



Tribe IV. Inuloidese 



Gnaphalium Sprengelii 

 Tribe V. Helianthoideas 



Coreopsis tinctoria var. atro-purpurea (cult.) 



Hemizonia fasciculata var. ramosissima 



Hemizonia tenella 

 Tribe VI. Helenioideae 



Chsenactis glabriusculus and other species 

 Tribe VII. Anthemidese 



Achillea millefolium var. rosea (cult.) 



Chrysanthemum (cultivated, pompom type.) 



Matricaria discoidea 

 Tribe VII I. Senecionideae 



Senecio Douglasii. 



For this examination many of the specimens were preserved 

 in diluted alcohol but this was found unsatisfactory and I think 

 the characteristics sought would be clearer even in dried speci- 

 mens; fresh ones are of course, the best. 



Erigeron does not show the separation well after soaking
