seem so striking. Wliile tiiiis noticinii; a selected range in reference to dissemination, 

 another peculiarity comes to mind, viz., tliat on these same hill sides, it .seems to select 

 a zone of growth. This zone commences about the middle of the hill and with this us a 

 base extends about halt waj- to the top; the plants being most thrifty and abundant on 

 the southern exposures. There is certainly something peculiar in this limit of range, 

 as the lower portion? of the hills ofier, to all appearances, as favoral)le con.ditions for 

 growth as the up])er. The same might also be remarked in reference to many local i- 

 ities back from the river. 



However the special object of this note is to point out some pecultar efl'ects of culti- 

 vation upon this plant. The specimens I have are froni the garden of Mr. E. A. Rau, 

 Bethlehem, Penn., and the peculiarities are that tluf leaves are promliwutli/ A tn 5 loJied — 

 lohes (trnte and invcranatc. I have just examined some 40 specimens collected here with 

 the following results: 80 per cent entire to undulate, and 20 percent distinctly toothed; 

 in no specimens that I have ever seen have the leaves appeared lobed. "We further no- 

 tice that the leaves of the cultivated Jeffermnia are 4 to 5 times as large as those 

 found in the woods and the pod is also much larger and lieavier. The flowers the wri- 

 ter has never seen, but would infer that they were also much larger. I take the liberty 

 to append a note from Mr. Rav; in reference to this plant. He says, "The Jeffevmnia 

 was taken fnmi the garden of Mr. Jacob Wolle, of Bethlehem, Penn., and as tiie plant 

 has been deteqted by Mr. Wolle near Narrowsville, Bucks county, along tiie Nockamix- 

 on rocks, this may be the source of the si)ecimens of which we write." Mr. Rau further 

 adds that however uncertain the length of time this has been cultivated by Mr. Wolle, 

 he knows it to have been under cultivation more than 12 years. Doubtless uian}- others 

 have noticed variations as a result of cultivation and failed to give publicitjMo their 

 observations. But it seems to me both interesting and protitidde to notice such marked 

 effects as the one just described. — A. H. Yot'NO, Hanover, Ind. 



N-VTURAL Grafting. — Some five miles north-west of Hanover I was surpriseil to 

 find a good-sized tree oi Gai-pinus Americana, or Water Beech, aiDparcntlv growinir on 

 the trunk of T^c^/yy.'? /<er/'M/72«f'/, or the common Beech. A closer examination showed 

 tiiat the trees had started close together, and instead v;f one crowding tlie othci- out, 

 they had coalesced, their bark had become continuous, and below where they fork it is 

 impossible to tell which is which. The fork looks like a regular ])ranch, the Water 

 Beech coming out at quite an angle, according to its usual habit. — J. M. (,'. 



Habenaria PERAMffiXA, Gray. — This showy Orchid has added much of beautv to 

 our collections lliis summer. Orchids arc exceedingly scarce in this range, and hence 

 the advent of one in any quantit}' is most welcome to liotanists. Now, the very interest 

 and peculiar attactiveness of this plant this year lies in its abundance. It was first found 

 here by the writer in July 1878, and has not been seen since by him, although I believe 

 others have collected a very few specimens. Now this year it appears in considerable 

 abundance both in the old locality and in many new ones, which in past years have been 

 tramped over again and again without any finds. It is hardly reasonable to suppose .seeds 

 have been borne to six or seven localities, as many miles apart, during the past year, and, 

 on the other hatid, if these plants have lain dormant so long there is much interest in a 

 rest of such long duration. — A. H. Y. 



Spermacoce oLAr.RA, MiciTX. — We are glad to be able to record the rediscovery of ih is 

 desirable pb'.nt. In 1S70 it was named in the list of Mr. A. H. Young, as growing in Jef- 

 ferson county on the river bank. As no specimens wore saved, Ihe discovery was prac- 

 tically of no value, ami after repeated .searches along the river bank doultt bcuaii lo ;irise 

 in our minds whelher we really were entitled to the plant or not. In ls74, in mv ineom-
