the name P. capitata, Hook. It is the large-leaved, large- 
flowered plant which flowers in late summer—the best of all the: 
plants in cultivation under the name P. capitata. From true 
P. capitata, Hook. and all the plants cultivated under the name 
it may be distinguished at sight by its large leaves with coarsely 
reticulate, almost honeycombed, snow-white under surface and 
the bright green upper surface which, although it has scattered 
meal-bearing glands, never becomes white. 
Six distinct plants are now in cultivation under the name 
P. capitata, Hook. with or without a varietal qualification. Of. 
these the P. capitata, var. crispa of gardens is the same as the 
garden plant P. capitata, var. erosa, and is not a form of the 
ageregate P. capitata, Hook. but is one of the aggregate re 
denticulata, Sm. (see p. 160). Excluding it then, we have five 
plants, which are P. capitata, Hook. or microforms of it. Four’ 
are Indian, one is Chinese. They are easily distinguished as 
they grow, and it may be helpful if I give here the following, 
key by which anyone can at sight distinguish them :-— 
1, Leaves on both surfaces green. Leaf-base green. 
Capitate umbel discoid. Corolla-limb open. crispata.. 
Capitate umbel globose. Corolla-limb funnel- 
shaped y : : . pseudocapitata. 
2. Leaves on under side snow-white with meal. Leaf- 
base green. Capitate umbel discoid. 
Upper leaf-surface more or less whitened with 
meal. Corolla-limb open i ‘ capitata. 
Upper leaf-surface green. Corolla-limb open . Mooreana. 
3. Leaves on under side cream-coloured with} meal. 
Leaf-base red. 
Upper leaf-surface more or less whitened with 
meal. Capitate umbel globose. Corolla-limb 
funnel-shaped . P ; ‘ .  lacteocapitata.
