In its relation to the formation of buds the stolon of the Salpre also behaves differently from that of Doliolum. In the latter, bud-generations sprout from the stolon; they are arranged in rows, are often dimorphic, and remain attached to the stolon by short processes. In the Salpee similar buds arise by outgrowth from the stolon, but each bud encloses within its

In its relation to the formation of buds the stolon of the Salpre also behaves differently from that of Doliolum. In the latter, bud-generations sprout from the stolon; they are arranged in rows, are often dimorphic, and remain attached to the stolon by short processes. In the Salpee similar buds arise by outgrowth from the stolon, but each bud encloses within its base half of the whole area of the stolon; so that when two rows of such buds are formed the material of the stolon itself is transferred to the body of the buds. The maturity of the chain-like connected series of young secondary buds (into which the primary bud divides) results, in consequence of this disposition, in a separation (Fig. 206, n) from the parent of the portion of the stolon concerned in its production.
