. Introduction to cryptogamic botany. Cryptogams. 210 INTRODUCTION TO CRYPTOGAMIC BOTANY. 1. ECTOCARPE^, Ag. Filiform, articulated; spores or cysts external, sometimes formed by the swelling of a branchlet. 194. "We begin -with the simplest forms, in which the frond is composed of a single simple or branched thread, or coated with cells, or very rarely solid and cellular below, giving off sub-globose spores or cysts filled with a dense endochrome, and active granules contained in distinct organs. There is some doubt about the nature of the former, whether they are simple or compound organs, unless indeed Ectocarpus sphcericus, D. and S., in which the globose lateral cysts were observed to give rise to active bodies, be considered decisive of the point. As regards the podlike organs, Thiu-et has shown, beyond all question, that their office is to produce zoospores, and analogy would lead us, even apart from E. sphcericus, to suppose that the endochrome of the other bodies is resolvable into zoo- spores of another order, as in Ulvacece, Be this as it may, the two organs are for the most part seated on distinct individuals, and it is probable that all the sUiculose Ectocarpi are mere.
