Between Drosera filiformis and D. intermedia. 93 
numbers, each measuring 40-44 4 in length. That of 
D. intermedia is provided with stomata which are 35-36 yw in 
length, but about as abundant as these are the two-celled 
glands typical of the species. In the hybrid the stomata 
average about 38 yw, while the two-celled glands of the latter 
parent are reproduced in size, but reduced in number. 
A slight reference may be made now to the structure of the 
cortex. In D. fiformis this is made up of 4—5 rows of thin- 
walled, richly chlorophylloid cells, with considerable inter- 
cellular spaces between. An indurated sclerenchyma zone 
next succeeds, composed of 5-6 layers of cells, which grad- 
ually become larger toward the interior. The amount of 
thickening is greatest in the second and third layers of scler- 
enchyma. The average thickness of the thickest walls is 
7-8 w. The chlorophylloid cortex of D. intermedia consists 
of 1-2 layers of cells with fairly large intercellular spaces 
between. Subjacent to this are 3-4 layers of slightly indur- 
ated, but mostly very large, cells from the second layer 
inwards. The average thickness of the walls is 3.5 4 The 
outer cortex of the hybrid is made up of 2-3 layers of chloro- 
phylloid cells, with relatively large intercellular spaces. Sub- 
jacent are four to five sclerenchyma layers, considerably 
less thickened than in D. filiformis, but which have, as in it, 
the most highly thickened zone in the middle of the mass. 
The average thickness of the thickest wall is 4.5 y. 
The fascicular system will not now be treated of, as equally 
in parents and hybrid it is complicated in arrangement. 
(c) L[nflorescence-—The scorpioid cyme of D. filiformis is, 
from the bud state onward, semi-erect, and the flowers are 
closely crowded along the false axis, against which they are 
closely adpressed. The number of flowers in an inflorescence 
averages 14. The cyme of D. intermedia is closely coiled in 
the young state, the component blooms are somewhat loosely 
arranged, they spread out in radiate fashion from the false 
axis and the average number of flowers is 8. The cyme of
