THE NfcW YORK BOTANICAL GARDEN MARINE ALQAE OF PERU, COLLECTED BY ROBERT E. COKER NEW YORK BOTANICAL GARDEN 02243056 Glossophora Kunthii (Ag.) J. Ag. loc. cit. no "Zonaria Kunthii Ag. Icon. Alg. Ined. 2: pi. 15? 1821. In beach drift, La Punta, region of Callao, December 1906, Coker 23 p.p.-, also, Jan. 25, 1907, Coker 32; “dredged very close to the Island of San Lorenzo,” region of Callao, Feb. 5, 1907, 'Glossophora 73 Coker 56 (plate 28); in the surf, Island of San Lorenzo, Feb. 5 1907, Coker 57 p p-\ on surf-washed rocks, Chincha Islands, June 18, 1907, Coker 192 p.p.', also, in same locality and habitat, July 13, 1908, Coker 493 p.p.; in one fathom, Isla Vieja, Bahia de la Independencia, July 20, 1907, Coker 09640 p.p. Nos. 23,32, 56, and 57 are from the type locality or near it. The specimens collected represent various ages and sizes of the plant, yet all of the mature ones, so far as we have examined them microscopically, appear to be tetrasporic. The largest plants collected attain a length of a little more than 30 cm. In the younger and middle-aged plants, a cross section of the thallus very commonly shows only a single layer of cells in the cortex, but in the older conditions the cortex consists of two and occa- sionally three layers, if one includes in the “cortex” a layer that often has a character somewhat intermediate between the surface layer and the medulla. We rarely find J. Agardh’s “fila brevia verticalia” except in the basal parts. The tetrasporangia occur on both the main thallus and the outgrowths from its surface. In the best-developed condition (no. 23), both surfaces of the thallus, with the exception of basal portions and occasional margins, are very densely covered with ligulate or spatulate foliola, which are often dichotomous, proliferous, or subpinnately compound, and commonly bear more or less numerous root-hairs on their margins and ventral surfaces. The original specimens were brought from Callao and “ Guan- chaco ” by Humboldt. The species has since been reported from the region of Callao by Piccone (Alg. Vettor Pisani 33. 1886). Pilger (Hedwigia 48: 178. 1908) attributes it to Chile also. JPlate 28. Glossophora Kunthii Photograph of a dried specimen {.Coker 56), reduced to about two fifths of the natural dimensions. 02243056
