Cassia calliantha

The epidermis cells very brown; in some places the chlorophyll looks quite healthy in the pallisade cells under the brown epidermis in other cells the grains are fused into a granular green mass: in others the whole pallisade cells are brown & shrunk: many of the 2ndary secondary nervures are very brown but not the main midrib: in some places the epidermis & vascular bundle are brown & the intervening pallisade cells green.

Pallisade cells form 3/5 of thickness of leaf

Cassia calantha

The upper epidermis cells differ from those of the ordinary cassia in being dome shaped, making an outline. [sketch] instead of [sketch]

Looking vertically down on a piece of epidermis each cell is seen to be studded with dots which do not disappear with ether & I cannot say they are bigger before ether treatment They only project very slightly as they are very hard to see with high power in sections.— I looked also it doubled leaflet after ether & before, but cd see no difference.
