Archive image from page 119 of Dansk botanisk arkiv (1913-1981). Dansk botanisk arkiv danskbotaniskark03dans Year: 1913-1981 Fig. 122. Galax- aura occidenta- lis nov. spec. Papillæ growing- out into hya- line hairs. (About 370 : 1). internodes and papillæ (Figs. 119 a, 120) protrude freely over the surface of the thallus and are not included in the chalk incrustation. In shape they are clavate-cyhndrical, having their largest diameter a little above their middle and then abruptly narrowed in, running out into a short apiculus. They are about 40 /u long and 11,« broad in their broadest part.
Archive image from page 119 of Dansk botanisk arkiv (1913-1981). Dansk botanisk arkiv danskbotaniskark03dans Year: 1913-1981 Fig. 122. Galax- aura occidenta- lis nov. spec. Papillæ growing- out into hya- line hairs. (About 370 : 1). internodes and papillæ (Figs. 119 a, 120) protrude freely over the surface of the thallus and are not included in the chalk incrustation. In shape they are clavate-cyhndrical, having their largest diameter a little above their middle and then abruptly narrowed in, running out into a short apiculus. They are about 40 /u long and 11,« broad in their broadest part. They are provided with a well developed chromatophore (Fig. 120), parietal, cuphke, with thin prolongations along the wall of the cell; in the middle a pyre- noid is present. Occasionally I have found 1—2 small cells at the summit of the papillæ which is then rounded and very rarely the up- per cell was also growing out to a long one- celled hair richly filled with protoplasm at the upper end (Fig. 122). Antheridial conceptacles (Fig. 123) were pre- sent in great numbers. They occur in the young are nearly spherical bodies wilh an opening through the wall of the thallus. Their wall consists of ramified filaments with larger cells growing closely together. From the innerside of these the richly ramified antheridia pro- ducing filaments grow up in the cavity. The anthe- ridial filaments are divided into small cells of which those at the apex (but later on also the other cells) are transformed into mother-cells for the sper- matia. The antheridia are about 8 fj. long and 5 fj. broad, oval. The anthe- ridial conceptacles have mostly a diameter of about 200—300 fjt but larger ones also occur. To the Sectio Vepre- ciilæ Kjellman only refers four species none of which are from the West Indies. Of these G. vepreciila Kjellm. seems to come very near to my plant. I have been able te compare my plant Fig. 123. Galaxaura occidentalis nov. spec. Transverse section of anantheridi
