Attention is called, in this brief note, to the fact that Vitis 



qiiinqtiefolia seems to produce two well marked varieties, one pro- 

 ducing sponge-Hke disks and hence cUmbing everywhere readily, 

 the other producing tendrils without disks which assist the plant 

 in clambering up rough surfaces only. We have seen mention 

 made of these two varieties before, and the importance of distin- 

 guishing between them is often highly important when the vine 

 is to be planted for ornamental purposes. Observation of the 

 natural geographical distribution of the two forms would be valu- 

 able. 

 Water Lilies — Notes on Mexican. C. G. Pringle. (Garden & 



Forest, iii. 415). NynipJia^a Mexicana, N. elegans, N. ampla 



and N. gracilis are described. 



In regard to the latter species the author says: ** Of the sev- 

 eral species under consideration this one alone, as I believe, pos- 

 sesses any marked fragrance. Its root-stock is a tuber rather 

 than a rhizome — or such at least it appears in autumn, after all 

 the rest of the plant has perished — an ovoid body one to three 

 inches in length, with thick and hard outer shell, covered with 

 bosses quite like a pine cone in appearance. In this state the 

 plant is prepared to hibernate and endure safely the droughts of 

 the earlier months of the year, when many of the shallow lakes 

 which it inhabits arc dried up, and the land, where they lie tum- 

 bling about on the surface, is even growing a crop of wheat."

Part two of this splendid work has been issued under the same 

 conditions as part one — Mr. James M. McDonald assuming the 

 financial responsibiHty and Prof Greene undertaking the neces- 

 sary botanical explorations and descriptions. The general style 

 of Dr. Kellogg*s drawings has been preserved, so that there is a 

 gratifying uniformity throughout, and this latter part is a fitting 

 sequel to the great work so well begun. Quercus Gilberti and 

 Q, vennstula are described as new. A problematic specimen of 

 Q. Ganihelli, from Bear Creek Caiion, Col., is figured and so
