SUPPLEMENT. 137 
Var. BARBATA (Gant.) Seen by Mr J. Groves. Mud 
at bottom of stagnant water in a quarry, Berstane, St. 
Ola (13th September 1913); native. 
CHARA ASPERA ( Willd.) 
Var. SUBINERMIS (Kuetz.) Seen by Mr J. Groves. 
Mud at bottom of water five feet deep, Loch of Board- 
house, Birsay (29th September 1913); native; very 
common in the loch. 
MALVA MOSCHATA (Linn.) 
Several plants of this species were found in grass 
land of Greentofts, Deerness, during August of 1913. 
These showy flowers were in full bloom. They have, 
no doubt, been brought with seeds, and the lovely 
summer of that year favoured their fine development. 
PARNASSIA PALUSTRIS (Linn.) 
Two curious monstrosities of the Grass of Par- 
nassus were brought to me from the Banks of Pool, 
Deerness, in August 1913. Its single-leaved stem and 
beautifully pencilled petals left no doubt as to its 
relationship. It had, however, as far as I could 
ascertain, only three stamens bearing anthers, and 
its numerous glands and antherless stamens had 
developed into petals. All these petals—from 25 to 
30—were pencilled with the same graceful lines.
