R. Lif)io.<bati L. is our most common form and, probably, is to be found 

 throughout tlu- state, with the exception, perhaps, of the extreme southwestern 

 counties. 



R. yruiile Michx. is reported definitely only from Vigo County, by W. S. 

 Blatchley, his plant being found in DePauw herbarium. It is probable that some 

 forms reportetl as i?. rotimdijolitnu Michx,, by earlier collectors, may be referred 

 to this form. 



R. rotiijidifolium Michx. is reported from .Jefferson County (J. M. C. ) and 

 Clark County (B. and T. ) No herbarium specimens of these collections are 

 available. It is probable, however, that this species does not occur within the 

 state and that the forms should be referred to R. grncile, rotundi/oliuvi being an 

 eastern and mountainous form extending from western Massachusetts and New 

 York south to North Carolina, following generally the Allegheny range. It is 

 probable that R. roluiuUfoliu'in will have to be excluded from the state list. 



R. <>xyoranfho!(fe>i L. is reported fom Noble (Van (i.), .Jefferson (.J. M. C. ) and 

 Clark (B. and T. ). Though no herbarium specimens have yet been seen, the form 

 doubtless occurs in the state. Specific reports as to its occurrence, with confirma- 

 tory speciniens, if possible, are greatly to be desired. 



R. foriduiiilJHer is Reported from Noble to Jefferson, through the eastern 

 counties of the State; it is not reported from western or southwestern counties. 

 While no herbarium specimens have yet come to my notice, it is doubtless a mem- 

 ber of our state floia. The latest stations are Montgomery County, near a swamp 

 (single station E. W. Olive), Madison County (Walker). 



R. rubruiti L. var. nubglandidosnm Maxim, is reported from Clark County ( l'>. 

 and T.), and .Jefferson (.J. M. C. ). No herbarium specimens have been examined. 

 The manual range includes Indiavia s])ecifically, an addition in 6th ed., probal)ly 

 based upon this citation. 



It is remarkable that of the sixteen species lepresenting this family in Indisina 

 (excluding two species of Philadelphus) seven are of extreme interest, either be- 

 cause of their rarity or because of their extending previous ranges. 



They are : 



Saxifraga Virginiensis, Michx. [Not authenticated.] 



SuUivantia Ohionis, Torr. and Gray. 



Tiarella cordifolia, L. 



Heuchera rillosa, Michx. 



Heuchera hispida, Pursh. 



Paiiiassia Caroliniana, Michx. ' » 



Ribes rubritm, L., var. subglandulosum, Maxim.
