Order XXXV. RANUNCULACEAE. 



125. Caltha palustris L. 



Common on damp ground, bj^ preference in watercourses and pools 

 of water, but hardly up in tlie hills. 



— — var. padicans (Forst.); C. palustris, var. zetlandica Beeby, 



The Scottish Naturahst 1887—1888; vide E. Huth: Monographie der 



Gattung Caltha, 1891, and Gunther Beck: Gliederung der Caltha 



palustris, Verhdl. d. zoolog-botan. Gesellsch. in Wien 1886. 



Near Kvalbo-rectorj^ on Syd. we found a form whicli matches C. radi- 

 cans Forst. It doubtless gradually merges into tlie typical forms and 

 can perhaps liardly claim to be called a variety ; intermediate forms 

 with cliaracteristic crenate leaves like the leaves of the C. radicans, but 

 stems not rootlng, were gathered by Rostrup near Thorshavn. 

 Fl. May. Fr. July. 



126. Ranunculus acer L. 



Common ever3'where in and outside enclosed fieids, on rock-ledges 

 and on the hills; in the latter frequently as i. piimila (Whbg.); e. g. Bordo: 

 Hojefjæld, 500 m.; Kalso: Blankeskaalefjæld at some 750 m.; Vid.: 

 Malingsfjæld 600 m. The lower part of nearly all the Færoese spe- 

 cimens is covered with stiff and spreading and very often dense, rusty- 

 brown hair. 



Fl. June— July. Fr. August. 



According to Trevelyan and Hornemann, R. nivalis waa found by Lyngbye, 

 and in the Museum of the Botanical Gardens, Copenhagen, there are a quantitj' of 

 Lyngbye's specimens labelled with this name, but this is not R. nivalis, but the 

 above-mentioned {. piiinila. Further Trevelyan records R. aiiricomus and R. hirsiitus 

 {R. sardoiis) and Landt mentions a »jR. hirtiis«^, but I regard all these statements 

 as referring to R. acer, the richly varied forms of which have caused these confusions. 



127. R. Flammula L. 



Common in low-lying regions amongst mosses and along streams, 

 often varying with regard to size and form. 



— — f. speciosa nov. formå, fig. 27. The plant erect-ascending 

 or erect, glaucous; stemleaves about 10 mm. broad, petals 6 — 8, 

 large (about 10 mm. long, 8^ — 10 mm. broad). 



This handsome form occurred on Str. near Orerenge mixed with 

 the typical form, but without merging into it. 



C. Bailey (Forms and Allies of Ranunculus Flammula L. ; Journ. 

 of Botany, 1887, p. 135) mentions a form (»the large -flowered coarse 

 growing erect form«), which perhaps is identical with m}' f. speciosa, 

 but he gives it no name. 



— — var. peptans (L.). 



San do: Sandsvatn (R., !); Ost.: Toftevatn (L., !) It grew submersed 

 and was somewhat coarser than is common with the Scandinavian 

 specimens.
