BULLETIN OF THE TORREY BOTANICALCLUB. Vol.XX. Laincaster,Pa., July i5, i893. No. 7. Newor NoteworthyNorth American Phanerogams-VII. BY N. L. BRITTON. (PLATE CLVIII.) Jacksoniia, Raf. Med. Rep. (II.) v. 352 (I808). Professor Greene has argued in Pittonia,ii. I74 and 274 that this name should replace Polanisia, Raf. Journ.Phys. lxxxix. 98 (I8I9), but I cannot see that his position is tenable. Jacksonia is published at the place above cited as follows: Jacksonia (trifoliata) Cleome dodecandra, L. Now Cleome dodecandra, L. Sp. P1. 672 is a well-known Indian species. Rafinesque evidentlyfollowed Michaux in supposing that it was North American,and Cleomnediodecandra, Michx. Fl. Bor. Amer. ii. 32 (IS03) is indubitablythe same as Polanisiagraveolens,Raf. Amer. Journ.Sci. i. 379 (iSi9), and not at all the plant of Lin- na-us. In mattersof nomenclaturewe must be exact, and so it seems to me that Jacksonia,Raf., can only apply to the Asiatic, Linna-an,Cleorne dodecandra. I do not findany allusion to Jack- sonia in subsequent writingsof Rafinesque,and presume that he discoveredhis error. Alsinie,L. Sp. P1. 272 (I753). I note that this generic name must,on the recognitionof priorityof place, and the beginningof nomenclaturein I753, clearly displace Stellaria, L. Sp. P1. 42I (I 75 3). As given in the Species Plantarum,the Linna-an Alsine is composed of A. media (Stellaria media, Smith) and A. segetalis, now referredto Tissa. 278 Rubus setosuls,Bigel. Fl. Bost. Ed. 2, I98 (I824). R. iispul'us, var. setosts,T. & G. Fl. N. A. i. 456 (1840). R. izispidus,var. sutberectus,Peck, Ann. Rep. State Bot. N. Y. for 1890, 31 (I 891). I have recentlyhad my attentiondirected to this plant by the examination of some of Prof. Charles H. Peck's material from NorthernNew York. He, in collectingit, saw at once that it was differentfrom any of the ordinaryRubi, and being unawareof Dr. Bigelow's previousdescription of it as a species, proposed it as a varietyof R. ihispidutsas cited above, a positionwhich had been earlier maintainedby Torrey and Gray. The plant is strikingly differentin appearance and habit fromR. izispidus,being much stouter,larger leaved, suberector ascending,the older wood most densely clothed with slender,stiff, slightly reflexed bristles, and I have no evidencethat it is evergreen. Its range, as I now know it, is fromQuebec to SouthernNew York and Pennsylvania,as the followingcitations of localitieswill indicate: Quebec (according to Bigelow); Thetford Center, Vt. (Jesup); Morehouseville, Caroga, Lake Pleasant and Brown Tract, Adirondack moun- tains, N. Y. (Peck); near Riverdale, New York City (Bick- nell); Sudbury, Mass. (Bigelow); Cambridge, Mass. (Nuttall); Pocono Plateau, Penna. (Britton). The flowersas indicated by Dr. Bigelow's and Mr. Bicknell'sspecimens are small. The fruit is reddish-blackand about I cm. high. The leaflets are mostly acute or short-acuminate,generally 5 on the leaves of the sterile shoots and 3 on the floweringbranches, short-petiolulate or ses- sile. Ruibnsvillosus, Ait. var. hzu4ifutsus,T. & G. Fl. N. A. i. 45 5 (1840). R. Canadensis,var. invisus,Bailey, Am. Gard. xii. 83 (I891). Some two years since, when Prof.L. H. Bailey was engaged in studying the Rubi which have been brought into cultivation fortheir fruits, he asked my opinion of the plant here alluded to, based on the specimenswhich had served as the type of the de- scription,and othermaterial which he at that time submitted. I examined the specimensand reached the conclusion,in which he subsequentlyconcurred after seeing them,that it was all referable to R. Canzadensis,L. I had not then seen the plant growing. Since then I have observedit growingin severalplaces, and numer- 279 ous field observationstogether with the accumulation of many herbariumspecimens have convinced me that it is distinctfrom eitherR. villosiusor R. Caizaden-sis,as indicated by Prof. Bailey fromProf. Dudley's observations(Am. Gard. loc. cit). The plant is exceedingly abundant on dry wooded hills in Southwestern Virginia,where it was pointed out to me by Miss Vail and Mr. Small, who had noted its characters,and whereR. CGazlde;isiswas not observedat all. It is also veryplentiful on the Highlands of Navesink, N. J., in the woods; occurs in Pennsylvaniaand Central New York, and some of the type material was gathered by Dr. Torreyat West Point, N. Y. Its range is doubtlessmuch' wider,however, than above indi- cated. It is a procumbentor ascending species, pubescent or nearly glabrous, the stem slender, sparinglyprickly, the upper leaves almost invariablyunifoliolate, and the racemes but I-few- flowered. The leafletsare broadly ovate or oval, acute or more commonlyobtuse, thin, the terminalones usually cordate, or all of them roundedor obtuse at the base; the fruitis small in all the specimens seen by me. The plant appears to be always a dry woods species. The specific name /zzirniszjtsushas already twice been used in the genus. I thereforepropose that this plant be known as R. INVISUS(Bailey). Two possible older names by Tratteninckare doubtfullycited by Torrey and Gray as synonymsof theirvar. Iizuifusuis,but I cannot satisfymyself that eitherof them applies to the plant. R. Canadenisisand its several varietiesare, in so far as I have observedthem, always strictlytrailing, glabrous or nearlyso, occur in open, sunny,sandy or rockysoil, have larger acute or acutish leaflets, the uppermost sometimes unifoliolate,but commonly 3-foliolate,the racemes several-flowered,borne at the ends of erect or ascending branches,the fruitlarge, sweet and succulent, and withthat of R. cunzeifoliusour best blackberries. Valeriaua paticfor-a, Michx. Mr. R. H. Ingraham,of Niles, Ohio, after reading my note on this species (BULLETIN, XiX. 223), obliginglysent me perfectlyripe fruitsfrom a specimen collected by him near Indianapolis,Ind., which have the pappus elongated and plumose as in the other species of the genus, thus showing 280 that my surmisethat they do not elongatewas erroneous. These fruitsare narrowerand much more lanceolatein outlinethan those of ProfessorPorter's specimen fromMillersville, Pa., and many of them are slender-pedicelled. GNAPHALIUM HELLERI, n. sp.

The close affinityof Coreeopsisto Bidens has repeatedlybeen commentedupon by modernauthors, and it has been more than once maintainedthat the two shouldbe regardedas congeneric. The principaldiagnostic character which has been taken as separating them is the downwardlybarbed pappus-awnsof Bidens,the species with awned pappus which have been admitted into Coreopsis,having the awns upwardlvbarbed. This characterhas been found to completelyfail in the case of Bidensfrondosa,L., which,as it occurs along the Lower Delaware River in Pennsylvania,New Jerseyand Delaware, has the awns eitherupwardly or downwardlybarbed, and I have observeddown- wardlybarbed awns in Coreopsisdiscoidea. It is also statedby Dr. Gray that some of the species included by him in the Synoptical Flora in Coreopsishybridize with Bidens frondosa. For all this,it is my opinion that the genus Coreopsisshould be maintainedfor the original types C. verticillata, C. tripteris,C. auriculata,C. bainceolataand their allies, which have a pappus of two short usually unbarbedteeth, a coroniformborder or 0, and that those which have a pappus of awns upwardlyor downwardly barbed should be referredto Bidens. The last six species of 281 Coreopsisin Dr. Gray'sarrangement in the SynopticalFlora would thus go to Bidens,with species of which they have everything else in common. Their names would then be as follows: BIDENS CORONATA(L.) Fisch. fide Steudel. Coreo.psiscoroiiata, L. Sp. P1. Ed. 2, I281 (I763). Coreopsisauiea, Ait. Hort. Kew. iii. 252 (I789).

It appears to me as though furtherobservation would demon- stratespecific characters for this plant. BIDENS ARISTOSA(Michx.). Coreopsisaristosa, Michx. Fl. Bor. Amer. ii. 140 (1803).
