The above description is drawn up from a séries of spécimens in Herb. 

 Kew. coUected by Seemann. This is Ihe only gathering of the plant which 

 is available for delailed examination, and Ihey agree in every respect 

 wilh Fenzl's description. Regel says he has seen only a single poor spé- 

 cimen, collected by Eschscholtz; and judging merely from this restricled 

 material, it seems lo be "only a form of St. petraea'\ The sheel in Herb. 

 Kew., covered with many examples of the small plante, oflfers sufficienl 

 material whereon nol only lo base a description, but to discriminate 

 differenlial characters. This galhering of Seemann's is therefore valuable 

 as afîording Ihe only available séries of authentic spécimens. In the work 

 referred Lo Seemann says; — "notwilhstanding Ihat ail the spécimens 

 collecled by me are without petals, I hâve no hesitalion lo refer Ihem to 

 Fenzl's 5. dicranoides : the corolla may hâve dropped off, as the season 

 was far advanced when the plants were galhered, or, as is the case with 

 other Alsineœ, il may be présent al one lime and abortive at anolher". 



In Herb. Mus. Brit. there is a sheel of anolher galhering by \)^ Neill in 

 1825, labelled "Slellaria ? dicranoides." The plant, however, does not 

 belong hère; il lookes quite différent when placed by Ihe side of 

 Seemann's spécimens, nor does it agree with Fenzl's description, as the 

 leaves are linear and prominenlly 3-nerved, and olherwise looks more
