ROSACEiE. [Rubus, 



columbbicBf puberuli, sa^pe purpurascentes, ad intervalla bipollicaria caules alteraatim proferentes. Caules 

 herbaceij erecti, e sumrao radice e flagellis orientes, basi squamis (stipulis) membranaceis, vel fuscis vel viri- 

 dibiis amplexicaulibus obvelatis. Folia singulis caiilibus 2-4, altema, temata, (vel rarius pedatira cpiinata,) 

 elongato-petiolata. Stipulm magnse, obovatae, nunc obtusse, nunc acutae, ssepius acumine brevi, basi attenuatae. 

 Petioli filiformes antice sulcatl, plerumque foliolum impai* longitudine superantes, primo glandulis pedicellatis 

 mox deciduis ciliati. Foliola subduplicato-seirata, pallide virentia, subtus pallidiora, impar petiolatura, ple- 

 rumque ovali-subrhomboideum, utrinque sensini acuminatum, acutum, rarissime obovatum et obtusum, semper 

 basi attenuate integerrimo ; lateralia subsessilia, imiequalia, saepius extus inciso-lobata. Pubescentla caulis, 

 petiolorum, folionim et stipulaiiun laxa, breviuscula, magis aut minus rara, et in foliis saepe fere obsoleta. 

 Flores erecti, terminales, rare axillares et terminales 2— 4-, (plerumque 3,) paniculati. Pedunculi unguicu- 

 lares, stricti, singuli folioli caulinis conformi, vel tantum stipulis folii abortivi suffulti, plerumque ebracteati, 

 laterales tamen interdum rudimento folii ut videtur ubi flos alter abortivi uni-vel bi-bracteati. Calyx basi 

 1 2-costato-angiilatus, 3-6-fidus, extus cum pedunculis pube brevi acuta villosus, et glandulis minutis, pedicel- 

 latis, deciduis obsitus ; laciniis sensim elongato-aciiminatis intiis versus apicem tantum pubescentibus, sub- 

 anthesin reflexis, mox erectis. Petala 5-6, alba, ovalia, obtusa, passim emarginata, ungue lato brevi, calyce 

 paulo altiora. Fi~uctus ruber : Acini pauci, vix edules. Rich. 



Hab. Throughout Canada, from Lake Huron to the Saskatchawan and the shores of Hudson's Bay, 

 near York Factory, abundant. — Following this plant, so well described by Dr. Richaidson, that excellent 

 Naturalist observes, " R. saxatilis, L. in multis cum prsecedente quadrat, at diversa videtur flagellis sterili- 

 bus, nudis aut folia tantiun ferentibus, nee nisi ad apices radicantes anno secundo caules emittentibus, aculeis 

 quamvis raris vix unquara nullis, floribus minoribus et calycibus pedunculisque eglandulosis." — I think the 

 R, (BgopodioideSf the R. parvijiorust probably, and the 7?. Canadensis^ Torreyy and Linn. ? may be referred 

 to the same species. 



15. R. mucronatMS ; caule herbaceo piloso inermi, foliis ternato-palmatis concoloribus 

 pilosis, foliolis rhombeis acutis serratis, stipulis ovato-lanceolatis acuminatis, floribus termin- 

 alibus geminis, laciniis calycinis lanceolatis acutis puberulis corolla brevioribus. Ser, in De
