Delesseria sinuosa (Good, et Wood.) Lam., Strömf. Algveg. p. 24. 



It grows in the sublitoral region, usually on other algæ, in a depth 

 of 3 — 20 (usually 8 — 12) fathoms. Collected with tetraspores in May — 

 June and September. The frond is 10 — 20 cm. high, the leaves 5 — 8 cm. 

 long and 3 --5,5 cm. broad. The form of the leaves is oblong or ovate, 

 in young leaves obovate. The lobes of the leaf are of varying greatness 

 and form, corresponding to the description of the f. typica and the f. querci- 

 folia; I have seen many intermediate forms between these two formae, 

 and they cannot be kept apart with distinct , characters. Sometimes 1 

 have met with specimens bearing prolifications, in most cases loose lying 

 specimens, which in all, except that they have the prolifications, agree 

 with common forms of this species (f. lingulata). 



Probably common round Iceland.

 p. 26. 



It grows in the sublitoral region in a depth of 3—10 fathoms, on 

 Laminaria-stems, and in rock-pools at low-water-mark. Collected sterile 

 in April — August, with cystocarps in November. The frond is 10 — 23 cm 

 high. The leaves are 5 — 18 cm. long and 1,5— 3,5 cm. broad. 



Rather common in SW. Icel. and S. Icel.

Fam. Bonnemaisoniaceæ. 

 Bonnemaisonia asparagoides (Wood.) C. Ag. 



In the herbarium of the Botanical Museum in Copenhagen there are 

 three specimens of this species, said to have been collected in Iceland. 

 1—6 cm. high. 



On one of the labels is written: „misit Faber". In Fl. Dan. T. 2579 a 

 specimen of this plant is given, regarding which Lieb m ami writes: „ad 

 littora Islandiæ pr. Reykjavik legit beatus Faber, cujus specimina mecum 

 communicavit cl. Hofman-Bang a . 



It is possible that this plant occurs in S. Icel. since it is known so 

 far north as Bergen (Norway) x ) and also occurs in the Orkneys.
