210 SHORT NOTES. 



less parted leaves. In size it ranks between A. vulgaris and A. 

 alpina ; the flower-stalks are long as in the latter, but the flowers are 

 large, duller, and with usually a reddish- brown tinge ; the leaves are 

 cleft down to about two-thirds of their length, with usually rounded 

 but in the upper half sharply serrate lobes ; the under surface is very 

 silvery, with adpressed silky hairs. We found it but sparingly in un- 

 cultivated places on the hills on sand, as on Yedoe, Skgellingfjaeld on 

 Stroemoe, Rejnsatind on Yogoe, Koregjov, &c., on Syderoe. A. fissa^ 

 Schum., Q. piwiila is a dwarf form abundant in grass on the higher 

 mountains, as at Kirkeboe and Yardebakken on Stroemoe, Kejnsatind 

 on Vogoe, Famien, &c., on Syderoe. Its characters lie in its small 

 size, thicker root-stock and strongly compressed habit, weaker leaves 

 with shorter petioles, small flower-stalks, with the portions between 

 the leaves well covered, and the always red-brown coloured perianths. 

 A. alpina, L., is very common, especially on the steep mountain sides, 

 but in company with the former up to the highest points. A dwarf 

 form of this is also found in some places, possibly caused by sheep 

 grazing.— E. Rostrup, in " Bot. Tidsskrift," 1870, pp. 30, 31. 



Botany of Iceland. — Groenlund has printed (Bot. Tidskrift, 

 1874-75, pp. 36 — 85) a revised list of the plants of Iceland, founded 

 on Prof, Babington's in the Linnean Society's Journal (xi., pp. 

 284 — 348). The catalogue appears to have been carefully compiled, 

 and all the species of which specimens have not been seen or about 

 which there is any doubt are, though entered in the list, not 

 numbered. In Babington's list all the doubtful plants were numbered, 

 and the total raised to 467 species ; Rostrup, by his more exclusive 

 plan, only makes 317 species, about all of which, however, there is no 

 question. A few considered varieties by Babington are species for 

 Groenlund ; the latter has also added a few species to the former list, 

 and made one or two alterations. The following are the chief points 

 of difi'erence in the two lists : — Draha alpina, L., additional ; CocMearia 

 officinalis, L., var. arctica, ditto ; Sinapis arvensis, excluded by Bab. ; 

 Raphanus Raplianidrum, L., additional ; Alsine kirta, Hartm ? var. 

 islandica, Lange, "forsan nov. sp.," ditto; Fragaria collina, Ehrh., 

 excluded by Bab ; Galium trifidum, L., doubtful ; Taraxacum palustre, 

 DC, included under L. Taraxacum by Bab. ; Hieracium rnurorum, L. 

 =H. ccesium, Fr., of Bab.; Euphrasia parviflora, Fr., and E. offici- 

 nalis ^ var. arctica, Rostrup, doubtful ; additional ; Veronica mari- 

 landica, not numbered = V. peregrina, L., of Bab. ; Armeria sihirica^ 

 Turcz. Fl. Dan., t. 2769, additional; Plantago horealis, Lange, Fl. 

 Dan., t. 2707 = P. alpina, L. ? of Bab. ; Betula odorata, var. Friesii, 

 liegel, additional ; B. humilis, Hartman {B. alpesfris, Fr.) ditto ; 

 {B. intermedia, Thorn., figured in Fl. Dan., t. 2852, from Steenstrup's 

 and Bab.'s specimens) ; Potamogeton marinus, L. = P. filiformisy 

 Nolte of Bab. ; Carex gla/reosa, Wahlenb., doubtful, see Fl. Dan., t. 

 2430; C<?r6a;c<7j9z7/i>e«, Drej., additional., Fl. Dan., t. 2844; Festuca 

 littorea, "Wahlenb., doubtful ; Glyceria conferta, Fr. = S. distans, 

 Bab. ; Lastrea spinulosa, Presl. , var. dilatata, additional. — The author 

 of the new list, equally with Prof. Babington, seems to have over- 

 looked Rottboll's valuable paper to which attention was called in this 

 Journal (1870, pp. 277—279). Probably the first recorded plant for
