abortion of the upper stigmatic papillae confined to the lower part 
of the style branches (Fig. 5, III). 
Type IV. Style branches elongated or short, flattened, trun¬ 
cate at the apex, hairy or papillose externally ; each branch ending 
in a brush of hairs considerably thicker and longer than those 
which clothe the outer surface ; stigmatic papillae in more or less 
conspicuous marginal lines, extending from the base to near the 
apex of the branches (Fig. 5, IV). 
Type V. Style branches truncate and penicillate as in IV but 
with the inner surfaces permanently together ( i.e ., the style 
branches do not diverge); stigmatic papillae absent; very similar 
to IV before divergence of the style branches has taken place; 
characteristic sterile pollen-presenter in male florets (Fig. 5, V). 
Type VI. Upper part of the style more or less swollen and 
and hairy; style branches very short; stigmatic papillae all over 
the inner surfaces of the style branches (Fig. 5, VI). 
Type VII. Style branches elongated or short, flattened, each 
ending in a triangular appendage covered externally and internally 
with hairs which are usually longer near the base of the append¬ 
age ; stigmatic papillae in conspicuous marginal lines extending 
from the base of the style branches to the base of the appendages 
(Fig. 5, VII and Vila). 
Type VIII. Style branches as in VII, but appendages conical 
and more elongated (Fig. 5, VIII). 
Type Villa. Style branches as in VII, but stigmatic region 
short in comparison with the long, slender appendages (Fig. 5, 
Villa). 
Type IX. Upper part of style more or less swollen and hairy 
externally; style branches very short or practically absent; stig¬ 
matic papillae all over inner surfaces (Fig. 5, IX). 
Type X. Style branches very hairy externally, especially on 
the outside of the stigmatic part which ends in a collar of long 
hairs ; style divided to the collar or more deeply; stigmatic papillae 
all over inner surfaces of style branches above the collar (Fig. 5, 
X and Xa). 
Type XI. Style as in X, but with the style branches remaining 
practically closed; stigmatic papillae as in X but exposed only by a 
slight divergence of the style branches (Fig. 5, XI). 
Type XII. Style branches elongated or short, flattened, hairy 
externally either from base to apex or only at apex, apex rounded; 
stigmatic papillae inconspicuous, in two marginal lines which may
