branch with the brush hairs on the outer face? In these tribes, 
therefore, the style characters are not uniform. They are of two 
divisions, one of which might be mistaken for Helianthoidee. 
HELENIOIDEZ, (Plate CXIX. Fig. 37-42). 
DIvIsIon I. 
The style branches of the hermaphrodite perfect flowers are 
short, with a distinct bunch of brush hairs at the tip. Papillee 
arranged in two comparatively wide lines along the edges of the 
flattened branches. This division includes the genera Helenium 
and Actinella. 
Division II. 
Branches of the style in the hermaphrodite perfect flowers are 
considerably longer than in division I, brush hairs distinctly not 
truncate forming only a slight enlargement. Brush hairs occupy 
the outer face for about one-third of its length. The papillz are 
in two lines on the inner face. This division includes the genus 
Dysodia. 
FHlelenium (Fig. 37-40). 
Hf. antumnale, L. Style branches are essentially as described 
in division I. The brush hairs (fig. 39) are cylindrical, obtuse. 
_ The papillz, (fig. 40) are short and obtuse. 
Actinella (Fig. 41-42). 
A. linearifolia (Hook.), Torr. & Gray. Style branches as in 
Helenium, only somewhat broader and shorter. Brush hairs as 
in Fig. 41, and stigmatic papillz as in Fig. 42. : 
Dysodia (Fig. 43). 
D. chrysanthemoides, Lag. Branches of the style as described 
for division II. Brush hairs shorter and broader than in Helen- 
Zum. 
ANTHEMIDE# (Plate CXX. Fig. 1-10). 
In the Anthemidee the three genera examined have a truncate 
bunch of brush hairs, as division I of Helenioideg. The style 
branches are somewhat broader and shorter than in that tribe. 
Achillea (Fig. 1-4). 
A. Millefolium, L. The style branches the same as in the 
tribe (fig. 1-3). The brush hairs (fig. 4) are broad and short.
