Baccharis® (Fig. 20, 38). 
8. halimifolia, L. Style branches of the staminate flower are 
shown in figure 38. The entire outer face and edges of the inner 
are covered with brush hairs. Stigmatic papillae do not occur 
on the remainder of the inner face. The brush hairs are cy- 
lindrical, obtuse (fig. 20). ; 
The branches of the pistillate flowers are twice as long as in 
the staminate. They are linear in shape, with an acute point. 
The papillz occur in two narrow lines along t’ e edges. 
INULOIDEA* (plate CX VIII, figs. 39-44). 
In this tribe the heads are heterogamous or diceciously homo- 
gamous, and the style, therefore, in most cases, does not possess 
both brush hairs and stigmatic papillz ; the relative arrangement 
of the brush hairs cannot therefore be used as a distinctive 
character. The style of the hermaphrodite sterile flowers is 
either two-branched or entire. The style of the pistillate flowers 
is two-branched, but there is no variation in the arrangement of 
the papilla. Gray says: “The style branches of the herma- 
phrodite flowers are flattish or filiform, not appendaged.” 
Pluchea*® (Figs. 39, 40). 
£. camphorata, (L.) DC. Thestyle of the hermaphrodite ster- 
ile flowers is entire ortwo-cleft. The branches of the two-cleft 
style are terete, short in proportion to their length. The brush 
hairs cover the entire outer surface of the branches. Below the 
_ base of the branches the style is covered with glands (fig. 39). 
The brush hairs (fig. 40) are short and obtuse. The style of the 
pistillate florets is two-branched, with both faces covered, or near- 
ly so, with papille. 
Antennaria® (Figs. 41-44). 
A plantaginifolta (L.}, Hook. The style of the staminate 
flowers is two-cleft or entire. The branches of the two-cleft style 
are somewhat clavate, covered over the outer face and edges of the 
inner with brush hairs. The remainder of the inner face does not
