This little plant I am dubious of placing, it seems intermediate betweén S. con- 

 tortum rar. fi pseudotetracerum NYjrdst. (N. Z. Alg. p. 37, t. IV, f. !)) and »SY. incon- 

 spicuum of the same author (Norg. Desni. p. 26, t. I, f. 11, 1873, = S. rriinutissiiiium 

 Auersw. in Rabh. Alg. Eur. No. 1428 saltem ex p., sec. Nordst.; et = S. subrefrac- 

 tum Lem. Desm. Aosges. p. 23, t. I, f. 3, 1888). It is minutely granular, with 3 — 4 

 minute teeth at the truncate apices of the radii wliieh are not expanded as in S, 

 contortum Delp. (Desm. Sub. Alp. p. 152, t. XI, f. 53 — 55). Noi:i)stei>t's N. Z. form 

 appears hardly to be S. contortwn var.

 formibus, dorso convexis, ventre paullo inflatis; angulis 8 — 4 in radios produetis; 

 radiis rectis attenuatis margine erenatis superfieie striate dentatis divergentibus apice 

 3 — 4-fidis; membrana sinuosa in centrali parte frondis non punetata nec granulata; 

 sinu sub-acuto, aperto. A vertiee visum 3 — 4-gonum, centrali parte hevi; lateribus 

 in centrali parte (in 3-gonum) planis vel leniter eoneavis, (in 4-gonum) angulis interne 

 planis vel latissime rotundatis.
