In Seedlings 1: 418. by Sir John Lubbock, there is a figure 
of a seedling of an European species of clover, 7rzfolzum Bors- 
stert Guss. This is evidently a yellow flowered species which 
should be placed in the genus Chrysaspis, a segregate from Tri- 
foliuin, as proposed by Dr. Greene. The drawing represents the 
first leaf as coming out from the main stem at some distance 
from the cotyledons, unlike any of the American clovers. The 
long pedicel to the central leaflet of the trifoliolate leaves is also 
shown, which is characteristic of some of the species of Chrys- 
aspls. 
The genus Trifolium is mentioned in a recent publication 
entitled ‘An investigation of the seedling Stiucture in the Le- 
guminosae,” by Robert Harold Compton, Journ. Linn. Soc. (Bot- 
any) 41: 1-122. pls. 9. The investigations were carried on at 
the Botany School, University of Cambridge, England, and show 
a large amount of painstaking and thorough work on the ana- 
tomical and histological characters of the seedlings of Legumi- 
nosae, with a review in tabulated form of all previous literature, 
Plate 1 shows photographs of the external character, such as the 
root, the cotyledons and the first leaf, or sometimes a few of the 
succeeding ones, of seventeen different seedlings. The remain- 
ing eight plates represent numerous drawings from histological 
sections, showing the fibrovascular systein of about forty species 
from all sections of the family. The only illustration which 
concerns our present work with the Leguminosae is that of 77z- 
folium arvense, an European clover, but naturalized as a weed 
in America in many places. The seedling is very similar to 
those belonging to the group here treated, as shown in our plate 
2. It is very probable that 7: arvense and its European rela- 
tives are closely allied to this group of American Trifoliums.
