144 BOTANICAL GAZETTE. 



w 



columns of the GtAzette, giving dates and peculiarities, and so great good would grow 

 out of this apparent evil. 



One mistake of the authors of our Catalogue is to deny many of our clearest, ad- 

 mitted species. Thus they reject our beautiful Trndescantia rosea, Rosa lucida, Pani- 

 cum awarum and Carex vana, holding that the latter is "merely an upland form of Carex 

 Peiinsi/lvamra,'" — cpiite unfortunately, as both species ^;wc together on upland or low- 

 land indifferently ! The season is not half over, but by a very fruitful visit of three 

 weeks to Lyons, Clinton and Cedar Rupids, I have a score of rare and valuable plants to 

 add t;) said Catalogue, whicli will be sent for verification, Avith the Report, to the editor 

 of the Gazette, so as to preclude all doubt. Five of these occur in Ames, viz : Euphor- 

 bia p/j'i/goiiifolia, L., July 22, CoUege and ceraeievy; EupJwrbia heniiarioides ? Nutt., 

 August 9, cemetery (not quite ripe); Iva ciliata, Willd., from Ames to Nevada, August 

 14: \ Pofamof/etoii Inrens, Jj. var. "ffluitnns, Gniy, Moses' farm, two miles east of Ames, 

 deep slough now nearly dry, growing in mud, submersed leave gone, July 31 ; with 

 Artemisia (Janadeusis, Michx., Vmes^ ISTG, abounds from College farm to Tama City, 

 on gravelly banks, roadsides. It occurs no further west. To whicli may be added a 

 beautif 1 specimen of Pentstemoii Cobarii, sent at my request from Crescent City, Iowa, 

 by 11. H. Teiry, who deserves great credit for its introduction from Nebraska, with 

 other rare plants. — R. Bukgess, Aiaes, Iowa. 



PtniE White Veiiben.\ Stkict.v. — This summer I found five pure-white specimens 

 oi" I", strlcta growing near each other. About forty rods from these were three others — 

 pcr'.iaps seedlings of the first. Eight miles from this locality one plant was found, and 

 tv.-eiUv miles from ihe five first discovered three others were seen. The points of inter- 

 est i.i regard to them were tlieir vvide distribution considering their rarity, their being 

 surrounded by numerous specimens of the usual color, no pale intermediate forms be- 

 ing near, and in three cases out of the four, where there was more thau one plant in a 

 place, they grew close togetiier, not being interspersed among the blue. Five roots 

 were examined to see if they snckered, but no such connection was found. No dift'er- 

 ence in structure was observed betM'een the white and the blue, excepting that the 

 flower spikes were more slender and pointed in the white than in the Ijlue. — J. M. Mil- 

 LiOi.\.N, Morrjaii county. III. 



Is Hem.vnthus L.ETiFLOKUs A GOOD SPECIES? — I liavc had I'easou to doubt whether 

 this sunflower is a distinct i)lant. According to Gray's Manual, it has yellow disk flow- 

 ers and acute involucral scales, "the leaves almost as thick as in //. rirjidus,^'' while the 

 latter is said to XvAXi^ parpU' disk flowers and obtuse »ci\\G?,. I can see no other difterence 

 between Ihe species, in the descriptions. Now, our II. rigidus usually has acute scales 

 (it is so described in Chapman's Flora!) and I have found near Oquawka, this season, 

 several plants of this species with a ye/too disk. The leaves vary greatly in size and 

 shai)e, on different jilants, from broadly ovate to almost linear, always thick and very 

 rough. The color of flowers is, I think, of small inqtortance. Mr. Bebb has found the 

 allied Rudbeckia hirta, (usually purple), with a yellow disk. Will some one who be- 

 lieves in //. Itetijlorus, defend that species and send me a specimen ? — H. N. P., Box 16, 

 Oquawka., III. 



Some Nv.mph.eas. — Dr. 11. C. Beardslee, of Painesville, O., writes as follows: "A 

 young lady of this place brought me, last week, a specimen of Nehimbiitm luteum, 

 Salisb., collected in Bass Lake, a small inland lake, 12 or 15 miles south of this place 

 and on the highlands 18 or 20 miles south of the lake shore. The locality was a sur- 

 prise to me. The same lady informs me that she found a Nyniplum with pink flowers, 

 mU fragrant. Our white i>ond lily is N. tuberosa of Paine, which is said by Gra}^ in the 

 Manual, never to \va\q. pink flowers. Either Nyiapluea odorata occurs in that pond, 

 which I can scarcely believe, or the petals of N. tuberosa are sometimes pink, or in the
