cymis floribundis primo dichotoniis postea racemiferis, racemis 

 longis secundifloris, aphyllis stipulaceo-bracteatis ; floribus breve

 obtusis late albo-marginatis, petalis calyce brevioribus roseis v.

 pyriformibus compressis, margine altero valde incrassatis, basi 

 attenuatis, sub lente minutissime tuberculatis, primo subfuscis

" Plante annuelle ou bisannuelle. Feuilles allongees, linearies. 

 Stipules le plus souvent ternes, subtriangulaires, presque aussi 

 larges a la base que longues. Pedicelles plus courts que la 

 capsule. Fleurs nombreuses, rapprochees en grappes assez serrees 

 ou en petites cymes denses. Petales plus courts que les sepales. 

 Graines d'un brun grisatre." Eouy & Fouc. Fl. Fr. iii. 310 (1896). 



It may be mentioned that, while Willkomm & Lange regard 

 it as an annual, Eouy considers it annual or biennial, while 

 Halacsy (Flora Grceca, i. 251 (1901)) describes it as perennial. 

 Although separated rather widely from S. salina by M. Eouy in 

 his "Conspectus of French Spergularias " (Bull. Herb. Boiss. iii. 

 222 (1895)), in nature the difficulty will be to separate aberrant 

 forms of one from the other ; the chief points of distinction being 

 the more slender habit, the fan-like spreading of the branches — 

 " caulibus numerosis in orbem expansis " — the upper branches of 

 which are aphyllous, the short peduncles and denser cymes of 

 smaller flowers, the somewhat smaller papillate seeds, which are 

 never winged, and by the base of the stipules being less enlarged. 

 It apparently prefers dry sandy situations in the vicinity of the 

 coast in full sun exposure. 



ANDEES DAHL (1751-1789). 

 By B. Daydon Jackson, Ph.D., Sec. L.S. 



The statement on p. 30 concerning Anders Dahl induces me 

 to send a short note about him, as very little seems known about 

 him outside his own country. 



Dr. J. G. Acrel, who carried out the sale of the Linnean col- 

 lections to Dr. J. E. Smith on behalf of the family of Linne, was 

 not unwilling that they should remain in Sweden, for he applied 

 to the Secretary of State, E. Schroderheim, that through him the 

 King of Sweden, then in Italy, might be invited to buy them ; 

 probably the King was never informed of this request, but the 

 delay in answering Smith's letter was no doubt due to Acrel 

 waiting tor an answer from Italy. 



There was, however, another person in Sweden to whom Acrel 

 turned, and that person was Baron Clas Alstromer. In his letter 

 Acrel referred to the Baron as the " most enlightened Maecenas of 

 Natural History in Sweden," and whether he would allow the
