certain Species of the Genus Chris lisonia. f 29 
In the cells of the epidermis a fungus occurs now and then, 
having a similar appearance to that found in the root of 
C. subacaulis, Gardn. 
If surface-sections of the stem are made, the stomata are 
seen to lie in all directions, both longitudinally and trans- 
versely ; in the latter case the guard-cells have a curious 
shape, being rounded and as broad as, or broader than, they 
are long ; other stomata have a most peculiar oblique struc- 
ture, the guard-cells, and consequently the pore, being more 
or less distorted and altogether abnormal in shape. The 
guard-cells are filled with dense granular contents, which are 
sometimes of a brown colour 1 . 
In a section through the thicker portion of one of the scales , 
which so thickly cover the stem, the cells appear loosely 
arranged with small intercellular spaces amongst them ; their 
walls are curiously thickened at the corners where they 
border on an intercellular space. Brown granules occur in 
many of the epidermal cells. On the dorsal surface of the 
scale are raised stomata, as in the stem. 
The bracts are of a deep orange colour. 
Structure of the Flozver . 
The calyx is shorter than the corolla. There are no glands 
on its surface. It is of a deep orange colour, like the bracts. 
The internal tissue is not loose, but the cells fit closely together. 
Stomata occur on both surfaces, though they are very few in 
number. As regards its form, it consists of a tubular portion 
terminating in four or five inconspicuous lobes, which are 
sometimes scarcely distinguishable. 
The corolla does not much overtop the calyx ; it has five 
equal, spreading lobes. On both surfaces it is thickly covered 
with very large glands ; the stalk of the gland is very long, 
consisting of six or seven elongated cells, with a very small 
1 I have been kindly informed by Mr. Percy Groom that similar distorted stomata 
occur on the scale-leaves of two saprophytic orchids, viz. Aphyllorchis pallida and 
Lecanorchis moluccensis , which were described in his paper, “ Contributions to the 
Knowledge of Monocotyledonous Saprophytes,” read before the Linnean Society, 
December 20, 1894.
