Proceedings of the Botanical Society of Penn- 

 sylvania for Sessions 1899=1900. 



January /j, i8gg. Dr. Adolph Miller in the chair. Mr. 

 C. S. Schumo gave " Notes on the Vegetation of California, 

 Mexico and Jamaica," and illustrated his observations on the 

 native and cultivated plants of these regions with a suite of 

 specimens and numerous lantern slides. 



A discussion was engaged in on " The Teaching of Botany 

 in Schools and Colleges," by Misses Nicholson, Simons, 

 Head, Sabold, Ide, and by Dr. Schmucker and Mr. Conard. 

 All emphasized the importance of natural science as a subject 

 to be taught in every grade of school and college work, but 

 the view was advocated that in the primary and grammar 

 school grades, it could best be introduced, at least at present, 

 as "Nature Study," in the English course. 



Mr. Roberts Le Boutillier exhibited seedlings of Rhipsalis 

 cassytha, while from Mr. Lonsdale of Chestnut Hill, came a 

 group of parent and hybrid begonias. 



Jamiary sy. Dr. Adolph Miller occupied the chair. A 

 paper by Dr. Martha Bunting was then read, entitled "The 

 Structure of the Cork Tissues in the Roots of some Rosaceous 

 Genera," which has already been published (page 5^). 



Professor Macfarlane communicated " Observations on 

 some hybrids between Droscra filiformis and D. inter- 

 media," which has since been published (page 87). 



The secretar)' then announced the formation of sub-com- 

 mittees for the study of plant groups, and the convener 

 appointed for each. Numerous orchid blooms were exhibited
