P. grandifloras. Glands are [sketch] 3 celled like in P vulgaris and there are also the almost sessile glands. In the parts of the leaf not quite near the base the glands are all the same along each se right up to midrib — But near base there are long multicellular glands stalks with small glands to them, near the midrib. The glands of the multicellular stalks have divisions: the glands are made up of about 4-6-8 cells compared with nearly 30 which shorter ordinary celled on a hair which the glands of the shorter kind of stalked gland {[sketch]} have

gland: stalk :: 2 :: 25 — Grandifloras— long

—" : —"— 10. 21 —"— short ∴ 12/2 = 6 represents the amount of abortion of the gland in long stalk
