76 NOTES OK THE MARINE BOTANY OP THE COAST OF NORFOLK, 



everywhere in the summer; the former is known in Scotland by the name 

 of Pepper-Dulse, from its hot biting taste. L. ohtusa seems rather rare, or 

 at least local; it is sometimes found plentifully betAveen Cromer and Siderstrand. 

 Id. dasijplixjlla was first found on the Yarmouth beach by Mr. Wigg, and 

 occurs not unfrequently along the coast from that place to Cromer. Ghrysi- 

 menia claveMosa is found near Brancaster; I believe this Sea- weed was also 

 first discovered on this coast by Mr. D. Turner. Ghylocladia Icalifonnis is 

 another species which was first added to the British list from specimens found 

 on this coast by Mr. Woodward; it occurs at Yarmouth and Cromer, but 

 not frequently. C. articulata is rare on this coast. C. parvula is found in 

 plenty between the tide-marks at Cromer and elsewhere. Corallina officinalis, 

 Jania ruhens, and Hildenhrandtia rubra are the most common of the Corallines. 

 Melohesia poli^morpha, with M. memhranacea and lichenoides, are not unfrcquent 

 on many parts of the coast, growing on other Algae. The beautiful Delesseria 

 sanguinea is common on the beach at Yarmouth. D. sinuosa, alata, angus- 

 tissima and Hypoglossum are found in tolerable plenty on many parts of the 

 coast. D. ruscifolia is rare. Nitophyllum pundatum is found in the summer 

 months growing on other Alga3 at Cromer and elsewhere. N. laceratum is 

 often found with the last. Plocainium coccineum is very common on every 

 part of the coast. Rhodymenia bifida occurs frequently at Yarmouth and 

 Cromer. JR. laciniata and jubata are often found at Yarmouth about May 

 and June. R. ciliata occurs in many places in plenty. R. palmata is very 

 common all round the coast. Sphoerococcus coronopifoliiis must be considered 

 a rare species; it occasionally occurs near Yarmouth. Qracilaria confervoides 

 is by no means an uncommon species at Cromer and elsewhere. Hypnea 

 purpurascens and Oelidium corneum are very common on most parts of the 

 coast. Oelidium crinale appears rather a rare species. Giyartina mamillosa, 

 JBhyllophora memhranifolia, P. rubens, Gymnogongrus plicatus,^^ Poly ides 

 rotundus, Furcellaria fadigiata, Peyssonela Duhyi, and Damontia filiformis 

 occur frequently on many parts of the coast. Halymenia ligulata is occasionally 

 found at Yarmouth and Cromer in the summer months. Oinnania far cell ata 

 was first discovered by Mr. Dawson Turner at Yarmouth, where it is found 

 not unfrequently. Kalymenia reniformis is rarely found on this coast. 

 Iridoea edulis, Gatenella opuntia, and ^Gruoria pellita occur not uncommonly 

 at Cromer. Naccaria Wigghii is a very rare species; it occasionally occurs 

 on the beach at Yarmouth in the summer months, where it was first found 

 many years since by Mr. Wigg. Nemaleon multifidum and Dudresnaia 

 Hudsoni are by no means uncommon. 



Chondrus crispus is very abundant on all parts of the coast; equally 

 common is Geramium rubrum, though this species being annual is found only 

 in the summer and autumn months, whilst the former being a perennial 

 occurs in the same abundance all the year round. The other species of 

 Geramium which are found on this coast are G. nodosum, echionotum, ciliatum, 

 and acanthonotum ; these occur frequently in many places in the summer
