Proceedings of the Botanical Society of Penn= 
sylvania for Sessions 1899-1900. 
January 13, 1899. 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 R/zpsalis 
cassytha, while from Mr. Lonsdale of Chestnut Hill, came a 
group of parent and hybrid begonias. 
January 27. 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 54). 
Professor Macfarlane communicated ‘Observations on 
some hybrids between Drosera filiformis and D. iter- 
media,” which has since been published (page 87). 
The secretary 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
