CAREX AND EPILOBIUM IN THE LINNEAN HERBARIUM 367 



While the herbarium evidence is strongly in favour of identi- 

 fying Linne's species with acutiformis Ehrh., the description in 

 Fl. Suec. accords better with gracilis Curt. Hudson's special 

 description of acuta cannot refer to gracilis ; on the other hand, 

 the publication by Ehrhart proves that he understood acuta L. in 

 the generally accepted sense. Perhaps the safest course, that fol- 

 lowed by Kiikenthal, is to drop the name acuta, writing C. gracilis 

 Curt, and C. acutiformis Ehrh. for the two species affected. 



29. 0. vesicaria. The type-specimen is our vesicaria. Attached 

 are two half-sheets ; the upper I believe to be very immature 

 panicea ; the lower is named by Smith " inflate Hud. Mr. Woodw d ." 

 Turning to Fl. Anglica, ed. 2 (1778), I find G. inflata thus de- 

 scribed : — " Carex spicis remotis subpedunculatis erectiusculis, 

 mascula erecta lanceolata, capsulis ovatis acuminatis calycis duplo 

 longioribus " . . . " Anglis, bottle Carex " (Bottle Sedge is still 

 in use for C. ampullacea). The Linnean specimen already men- 

 tioned is excellent C. rostrata Stokes, 1787 (ampullacea Good., 

 1794) ; the references to Ray and Mori son under C. vesicaria fi. and 

 y. of Spec. Plant., ed. 1, also appear to mean this species. Appa- 

 rently C. inflata Huds. should be retained for C. ampullacea Good. 



B. — Epilobium. 



1. E. angustifolium. This is represented by a weak, narrow- 

 leaved, small-flowered state much like the alleged E. rosmarini- 

 folium fron Glen Tilt. I suspect that it was gathered in the far 

 north of Scandinavia. 



3. E. hirsutum is the ordinary plant ; but fi. is represented by 

 E. Lamyi F. Schultz, as determined by Haussknecht, who identi- 

 fies E. virgatum Fr. with E. obscurum; the obscurum of Fries 

 being apparently not Schreber's species, but E. Lamyi. The de- 

 scription of E. hirsutum, ft. in Spec. Plant, ed. 1, can only apply 

 to E. parvifloruvi Schreb. 



5. E. tetragonum. The type-specimen is a slender E. roseum 

 Schreb., with remarkably narrow, almost linear-lanceolate, leaves. 

 In Spec. Plant, ed. 1, the short description runs : — " Epilobium 

 foliis lanceolato-linearibus denticulatis, imis oppositis, caule tetra- 

 gono. Sauv. monsp. lb. Lysimachia siliquosa glabra minor. 

 Bauh. pin. 303. " In ed. 2, M lanceolato-linearibus " is altered into 

 " lanceolatis. M This, to my mind, completely upsets the conten- 

 tion that Linn6 intended E. adnatum Grisebach ; especially in 

 view of the omission of the adnate stem-leaves, which afford the 

 most striking specific character. On the other hand, the E. tetra- 

 gonum of Flora Londinensis is good E. adnatum ; and I believe 

 that the name E. tetragonum Curt, is unobjectionable. 



7. E. alpinum. The type is a rather small but well-marked 

 E. lactiflorum Hausskn. (determined by Haussknecht). The de- 

 scription in Spec. Plant, (ed. 1 and 2): — " Epilobium foliis oppo- 

 sitis ovato-lanceolatis integerrimis, siliquis sessilibus, caule repente " 

 cannot cover E. anagallidifolium Lam., but fully agrees with 

 Haussknecht's species ; and, by the rule of priority, his name 

 must give way to E. alpinum L. " Habitat in Alpibus Helveticis,
