Plants; Plants -- Denmark. — 5 Before entering on the description of the plant I may yet add that when Maze and Schramm (1. c. p. 178) write: "II n'existe qu'un seul specimen de cette plante, qui ne s'est plus montree sur les cotes de I'ile depuis 1870", this remark does not quite agree with the real truth as I have had an opportunity of seeing 3 specimens in the above mentioned Herbaria and of the specimens found here at all events the one in Agardh's Herbarium is a large one while that in Herb. T h u r e t is only a fragment. The specimens when living had a very gelatinous and lubricous surface so that they slipped out of one's hand like an eel; on the other hand the consi- stency was rather tough. The colour was a dark red- brown. The thicker main branches which reach a thickness of about IV2 cm. were somewhat compres- sed, the thinner nearly terete. The surface was smooth in places, being somewhat curled or crisp especially in the thicker branches. The plant was fastened to stones and shells on the bottom by means of a small roundish disc at the base. The specimens were irregularly ramified on all sides, often too with numerous proliferations at the apices (cfr. plate 1). On drying they adhere strongly to the paper and gradually take on a dirty yellow-brown colour. A transverse section shows the middle of the thallus to consist of a tissue of colourless, rather poorly ramified, cell-threads which are loosely interwoven (Fig. 3 E); the cell-threads are from 2 to 12 u thick and consist of rather long and thick-walled Fig. 3. Nemalion Schrammi (Grn.) B0rgs. A, assimilative filaments with two carpogonic branches (140:1). B and C, groups of carpogonic branches (B, 160:1, C, 140:1). D, cystocarp with decayed trichogyne (140:1). E, colourless cells from the middle of the thallus (140:1). F, Two assimilative cells with chromatophore, pyrenoid and nucleus (250:1)..
