anj' mention of the numerous prairie forms we found in the conditions just 

 indicated will be made under the hetid of prairie flora. 



IV. The flora of the tamarack and sphagnous swamps. These swamps 

 are found along the Kankakee, but chiefly in north-eastern Indiana. The 

 one we examined was near Kendallville, on the L. S. & M. S. R. R. If one 

 is delighted with his first botanical trip upon a lake, he can scarcely be less 

 so with his first experience in a tamarack swarap, with the dark branches 

 of Larix above his head and a soft cushion of SpliagniDii under his feet. 

 It is in such places that I think we will find our rarest forms and I regret- 

 ted exceedingly that our visit lasted but one day. We noticed that three* 

 species of moss chiefly covered the ground, viz: Sphagnum sqiiarrosum 

 S. cuspidotiwi and Leucohryam (jlaucitm. Growing abundantly upon these 

 moss banks was Drosera rotund i folia., and each gland upon the delicate 

 leaves had exuded a clear drop of fluid that glittered like a dew-drop, show- 

 ing how beautifully appropriate is the name "sun-dew." Then there was 

 Sarracenia pHrpnrea, Elodes Virginica, Campa)iula aparanoides, CaJopoqon 

 palchelhis, Cijpripedhan puhescens, C. acaide, Smilacina h'tfoUa, Osmunda 

 rcgalis, etc. We found several bushes of Bettda puniiJct which seem to be 

 intermediate between B. pumila and B. gfandidosa. The leaves are gland- 

 ular dotted and there are many resinous, wart like glands upon the glabrous 

 branchlets; but the bushes were 6 or 8 feet high and the leaves pale be- 

 neath with finely reticulated veinlets. Around the edges of the swamp, in 

 wet ground, before the tamarack begins, we noted Clematis Virginiayni, 

 Potentillafruficosa, Cornus stolonifera, Aster long ifol ins, Cnicas muticus, C. 

 discolor. Lobelia Kahnii, Salix Candida, Scirpiis ralidus, Carex comosa, C 

 Jiai^a, etc. 



V. The prairie flora. The prairie of Indiana is found in a tier of coun- 

 ties farther south and the flora is as well defined as that of the lakes. Here 

 thrive principally the large and coarse Compositce and some peculiar Legii- 

 minosce. To tell of all the plants we found upon the j)rairies or that had 

 extended from them along the railroads, would take up too much space 

 and I can mention only the best marked. There were Linum sulcatum, Beta- 

 losfemon ciolx(cens, P. Candidas, Ainorplia ccoiescens, Guara biennis, Eri/nr/iuni 

 guccafoliain, Liafris scariosa, L. spicata, L. cglindracea, L. piicnostacliya, 

 Solidago stricta, S. rigida, S. 31issouriensis, S. gigantea, Silphinm lacinia- 

 tiiiii, S. terebinthinaceum. S.integrifolium, Parthenium integri/olium, Rudbeck 

 ia subtomentosa, Lepachi/s pinnata, Helianthus Iwtiflorus, H. occidentalii, 

 TI. mollis, H. gigcmteus, H. grosse-serratus, H. divaricatus,. H. hirsutus Co.-
