Note 2779 — II.—CRYPTOGAMOUS or FLOWERLESS PLANTS.
Reading edition
The Pharmacopœia of India (1868) names Sphærococcus confervoides Ag. (Gracillaria Grev.), a plant of the Atlantic Ocean and Mediterranean, not uncommon on the shores of Britain, as furnishing a portion of the drug under notice. Specimens which we have examined are widely different in structure from S. lichenoides, and are apparently devoid of starch.
