and general absence of mealiness, it is characterized by thinner 
and larger, very long-petioled primary leaves, sometimes over 5 
cm. wide, which are more broadly cuneate at base and usually 
more irregularly and acutely sinuate-toothed, and even aristulate- 
acute; a larger fruiting calyx with more sharply and abruptly 
carinate sepals ; a somewhat larger utricle, flatter and rather more 
abruptly contracted around the edge to a blunter margin and usu- 
ally darker and more distinctly rugulose-pitted. This plant often 
becomes coarser and taller and more widely branched than C. 
album and its flowering period appears to be somewhat later. 
* CHENOPODIUM LANCEOLATUM Muhl. 
C. viride L. in part. 
Occasional or frequent, especially along shores. 
This plant is nearer to C. paganum than to C. album but in its 
typical form is widely different in appearance from either. It varies 
from bright green with little or no mealiness to paler green and 
somewhat scurfy-farinose. It is often low and diffuse and slenderly 
much branched, the inflorescence consisting of scattered glomer- 
ules on very delicate or even thread-form flexuous branchlets, 
the leaves lanceolate to linear-lanceolate and entire or subentire, 
the uppermost reduced to narrowly linear bracts subtending many 
of the glomerules. 
The citations underlying the Chenopodium viride of Linnaeus 
make it appear that his species was made up of three distinct 
factors. One of these was probably the plant later described by 
Reichenbach as C. paganum ; another seems more certainly to 
have been the plant proposed over half a century later by Muhlen- 
berg as C. danceolatum, The remaining citation alone refers to a 
published plate and may therefore be taken as fixing the type of 
the species. This plate represents the European plant known as 
C. opulifolium of Schrader and, indeed, formed the basis of that 
species. 
* CHENOPODIUM MURALE L., 
Occasional or frequent in waste places in or near the town; 
Madequet ; Siasconset. When growing in dry, sandy soil it is 
sometimes much reduced in size, with small somewhat fleshy 
leaves abruptly narrowed to the petiole, and contracted panicles ;
