Old prothalliare funnel-shaped, not flattened as is usually the case elsewhere, and a tuber-cular archegoniophore - arises behind the meristem instead of the usual flatcell-cushion bearing archegonia. This archegoniophore pierces the hinder portion elongates mostly into a stalk, the front portion bearsa roundish tubercle within which is much starch and other tubercle is thus very like tubercles which we have seen in manyHepaticae and is in a condition to persist through dry periods, and if it.
