is surprising how few entomophilous species occur; Liliiflorae and 

 Orchids are very sparsely represented. 



My noles on the flowering and fruiting of each separate species, 

 as I have observed these and recorded them in my lists (Ostenfeld 

 1901 b and 1907), show that altogether 36 species do not ripen their 

 fruits, or cannot do so with certainty year after year. 



Landt mentions, for instance, (1800, p. 184) that during a stay 

 of 7 years on the Færoes he nowhere found Memjanthes in bloom, 

 whereas Rostrup (1870, p. 50) says he found it blooming every- 

 where; according to my own observations it was in bloom in a 

 few piaces, and I found a few fully developed fruits. A similar 

 irregularity has been observed with Myosotis pahistris which Sim- 

 mons found with ripe fruits in 1895, while in 1897 at the same 

 time of the year I could find no developed fruit at all. This same 

 happens with other species. 



The list given below is based on my ow^n observations, on 

 information from Mr. R. Rasmussen, and from examination of her- 

 barium material. 



Agropyriim jiinceiim, ears produced as usual, but I did not succeed 



in finding any developed fruit. 

 A. repens, like the previous species. 

 Chamaeneriiim (Epilohium) angiistifolhim , flowers late and rarely, 



no fruit observed (cfr. Ostenfeld 1907, p. 851). 

 Cirsiiim arvense, flowers very late, no fruit observed. 

 Corniis suecica, flowering and fruiting sparse and variable in diffe- 



rent years. 

 Digraphis arundinacea, like Agropyriim jiinceiim. 

 Iris pseiidacoriis, flowers sparingly, but no fruit observed. 

 Juncus ohtusiflorus, seems to flower very late and sets hardly any 



fruit. 

 Lathyrus pratensis, flowers, but does not set fruits. 

 Lotas corniciilatiis, var. carnosiis, flowers, but does it set fruits? 

 Malaxis paliidosa, found with flowers, but no fruit developed. 

 Mentha aquatica, always found without inflorescences. 

 Menyanthes trifoliata and 



Myosotis palustris, var. strigulosa, already referred to in text. 

 Phragmites communis, always found without inflorescences (occurs 



only in one place). 

 Polygonum amphihium, very rarely flowering, but no fruit set.
