Note BI — GLOSSARY OF TECHNICAL TERMS USED IN PART III.

Braem (op. cit., p. 3, pl. i, fig. 1), has described and figured under the name P. fungosa var. coralloides, Allman, a dense form that somewhat resembles this phase of P. fruticosa but has become compacted without external pressure. It is, however, probably a form of P. repens rather than P. fungosa and differs in its broad statoblasts from any form of P. fruticosa. I have examined specimens of the same form from England.
