bases of the eee of the slight protuberances which suggest to 
my mind incipient spurs. In the case of two flowers an auxiliary 
spur had been developed from one of these sacs. One flower some- 
what resembled Dielytra in appearance, save that it was trimerous. 
There were three sepals, three large petals (and a fourth rudimen- 
tary) of about the same size, two erect and the third slightly 
spreading. From these had developed three spurs, two slightly 
smaller than the third, but larger than the spuris normally. Fou

Examination of 1000 flo sitet gathered between Bookham and 
Westhumble showed that as many as 890 were marked by the for- 
mation of distinct sacs at the twos of the petals (in addition to 
the usual spur). Thirteen of the remainder possessed the common 
feature that some or all the petals were lobed in a varying ey Si 
This lobing of the petals extended from an obscure lobing to a 
more distinct fissure, and occurred once or twice on a petal. In 
the case of the upper petals, the lobing was usually down oy centre,

petals saccate at the base. The lower petal that should have borne 
the spur possessing a more distinct sac than the others. Staminal- 
processes suppressed. In addition to the usual tufts of hair on the 
me al petals a similar tuft was developed on the lower petal.

usual petal spurred and the remainder saccate, one to such an 
extent as to form a small spur. 4. Four sepals as usual; a fift 
lying along the spur and so assuming an opposite direction to the

base. Four stamens and one staminal-process deovelisea. . Fou

one with a spur and staminal-processes. Of the stamens four were 
normal and one shrivelled and abortive.
