19. Cutleria. Grev. Cutleria. 



Frond piano-compressed, cartilagineo-membranaceous, sub- 

 flabelliform, irregularly cleft. Root a mass of woolly filaments. 

 Fructification; minute tufts of capsules, scattered on both sides 

 of the frond, the capsules pedicellate, containing several distinct 

 granules. Grev. Alg. Brit. p. 59. t. 10. — Named in compliment 

 to Miss Cutler of Sidmouth, the discoverer of Grateloupia fili-

Cast on shore on Yarmouth beach, Messrs. Turner and Wigg. ©. 

 August. — Frond of an olive-brown colour and cartilagineo-membrana- 

 ceous texture, but adhering to paper when dry, broadly flabelliform, 

 cut nearly to the base into 3 — 5 cuneate primary segments, and those 

 again copiously divided into numerous, irregular, but more or less 

 linear ones. Fructification scattered over both surfaces of the frond, 

 consisting of clavate pedicellate capsules, arranged in small clusters. 

 These capsules Dr. Greville aptly compares to the little black Fungus 

 so common on rose-bushes in gardens, the Phraemidium mucronalum. 

 Link. 



20. Padina. Adans. Padina. 



Frond flat, highly reticulated, subcoriaceous, flabelliform, 

 mostly undivided, marked with concentric lines. Root, a mass 

 of woolly filaments. Fructification; ovate, blackish seeds, fixed 

 by their base, bursting through the epidermis in compact, con- 

 ceiltric lines (rarely spots), mostly on one surface of the frond. 

 Grev. Alg. Brit. p. 61. t. 10. — Name of uncertain origin, a- U 

 the case with many of Adanson's Genera.
