The extreme iiaucity of note-, accompanying, scr\c to cmphasi/.c certain 

 features of the papci-, which 1 had the honor to present to the Academy last year, 

 lieyond the mere fact of the "Station" which niigiit mean any point in an entire

 the state. 



//. AmeriniiKt L., is nnu-h more abundant and more generally distrihuted tiian 

 •either H. villii.t(i or Jl. Iiispida, indei-d with perhaps the I'xception of liibes and 

 JlydraiKjea the most marki-d inemhcr of the family in the state. It is definitely 

 reported from twelve (12) counties and is probahly found in all parts of the state. 



II. hifpldii I'lirsh has been collected from Vigo County by W. S. IMatchley 

 and Ills dett'iiiiination is verified by a spe<'iinen in the OePauw heriiarium. I 

 have made no critical study of the form and am not able to |)ass u|)on tiie accuracy 

 ■ol the reference. Tlie range of this species is somewhat strange. Its home seems 

 to bt' ill the iiioiiiitains of Vii'ginia, it is also rejiorted from Illinois by I)r. Mead, 

 fiiim which point its range is iiorthwt'St ward. We now seem to ha\c an interven- 

 ing station in Indiana, somewhat the more i-emarkalilc as occurring in tlie low- 

 lands of the state. 



Puniassia CarolinaiKt M'lchx. occurs in the iioilliern part of the state, being 

 ri'portcd from Xoble County by \'an (iorder and Kosciusko liy W. S. lUatchley, 

 the latter collection being in the I)el'auw lieibai'ium. The region i'e])<'rtcd is the 

 one in wliieli tiie form woiibl Ur ex|ieete(l in our state. Its i-ange would probably 

 be fouuil to covt'r most of our iKUthciii counties, if investigations weie maile 

 during July-Septemiier. 



llydranifa arborcM-enx L., as far as our present knowledge goes, seeius to be 

 fairly abundant fr(un northern central counti^'s. xiulliwanl. It is not, however, 

 r<-poi'ted from the northern tici' of counties, altlioiigli it may oeciii- in favorai)lc 

 loealities. 



liihe-< is our most imp(U'tant genus, imt only in numlH'r of species, but also in
