The delic'Jite little Creeping Sela<iiiielhi (S,l,iq! n< ll<i i/j>i/m\, has 

 been found fossil on the brink of the (I rand Can on of the YeUowstone, 

 in the Yellowstone National Park. It is found in an indurated elay 

 which was with little doul>t deposited during glacial times. This 

 species is now found from Ontario to the Northwest Territory and 

 south to Florida and the Gulf States. — F. H. K. 



Have anv of our readers ever hear>l our j)retty little 'Inirrlln 

 coril'ifiiJid called Foam Flower? It appears from the last number of 

 TJic ('(irdcii that it is so called in Kngland, where it was introduced 

 into cultivation over 150 years ago, and this is certainly a more 

 euphonious and <lignitied name than that of False Mitrewort l)y which 

 it is usually known in its home. Thr (innh n has a picture of a beau- 

 tiful mass 20 feet square as grown in a hardy l)order. It should 

 undoubtedly be more widely known here as it is of the simplest 

 culture. — F. H. Knowlton. 



In the recently issued number of Minnesota Botanical Studies 

 (Second Series, pt. iii) Mr. K. C. Davis has two valuable articles, the 

 first sivinof a careful svnonvmic account of the native and garden 

 Aquilegias of North America, and the second a similar treatment of 

 the native and garden Aconitums of North America. The method of 

 treatment is the same as that followed by Mr. Davis in hisi)aper on the 

 Pieonies in the present nund)er of The Plant Wohi.d. These pai)ers will 

 be found exceedingly useful, not only to the trained botanist, but to 

 the horticulturalist and amateur. 



The synopsis of Mexican and Central American Umbelliferae, by 

 John M. Coulter and .] . X. Rose announced in the last number, was 

 issued on January 8, and shows how ra[)idly the knowledge of this 

 group has advanced within the past twenty years. The tirst complete 

 enumeration was that of W . B. Hemsley in 1880, at which time 25 

 genera and TO native species were recognized. The present })aper 

 enumerates 39 genera and 182 species, or considerably more than 

 twice the number recognized by Hemslev- The systematic portion is 

 preceded l)y a careful generic key, and all obscure as well as new 

 species are fully described. The paper, which is beautifully printed, 

 is illustrated by numerous text tigures and twelve full-page plates, and 

 is an invalual)le addition to the literature of this difficult group. It is 

 published by the Washington Academy of Sciences.
