Type 13. Apical appendage present; basal appendages acute ; 
auricles with long tails divided into two or more filaments (Fig. 
6, 13). 
Type 14. Apical appendage elongated (oblong not triangular); 
basal appendages obtuse; auricles with long, flattened, lacerate 
tails (Fig. 6, 14). 
Type 15. Similar to type 14, but apical appendage more 
elongated and tails of contiguous anthers connate (Fig. 6, 15). 
Type 16. Apical appendage more elongated than in any other 
type; basal appendages flattened, elaborately lacerate tails, free or 
those of contiguous anthers connate (Fig. 6, 16). In one genus, 
Tricliolepis, the fusion of the anther tails has been carried further, 
giving a continuous, membraneous cylinder around the base of the 
anther tube (Fig. 6, 16a). 
A nalysis of the Stamens of Compositce. 
Analysis of the occurrence in the family of these various types 
of stamens show that type 1 is a special type occurring only in the 
specialised sub-tribe, Piqueriinae, of the Eupatorieae; type 2 is like¬ 
wise a special form occurring in a few genera only, while type 3 
occurs in a large number of genera belonging to eleven of 
the thirteen tribes. Type 4 also occurs in most of the tribes but is 
much less common than type 3, which is obviously the primitive 
and characteristic stamen for the family. Given type 3 as the basal 
form it is easy to see that types 1 and 2 are reduced forms while 
the others form a progressive series which may be given diagram- 
matically thus:— 
6a 6b 
4a |/ 9 12 15 
2 \ i / 6 \~ 7 / / / 
>3—4/ \_8—10—11—13—14—16—16a. 
Keeping this evolution of form in mind we can now analyse 
the composition of the tribes and sub-tribes of the family as regards 
their stamens in the same way as the styles have been analysed. 
The main points to be noted in Table VII are the following:— 
The primitive character of type 3, as already pointed out; 
Type 3 occurs in all the tribes except the Vernonieae and 
Cynareae; it is predominant in the Astereae, Eupatorieae, Anthemideae 
and Senecioneas; 
Type 4 occurs in considerable proportion, with type 3 pre¬ 
dominant in the Heliantheas and Helenieae ;
