Contents of gl Glands much flattened thin, like membrane— with a many radiating cells. Glands on flower-peduncles — Glands small very numerous. — Glands with purple included matter, — Glands of structure of Pinguicula, showing no [illeg] of digestion & structure of pedicel, or presence of spiral vessel. — Pedicels about as long as diameter of upper extremity of leaf.— Terminal Knob are 1/3 wider than end of leaf. — Pedicels colourless, transparent.
