Southern and eastern sea-coasts of England, chiefly in salt marshes 

 among Atriplex and other saline phaenogamous plants. N. Wales, Rev. 

 Hu ; >Ji Davies. ©.? Summer. — 1 — 3 inches high; a dubious plant as to 

 genus. Roth describes minute, axillary, roundish capsules, and lan- 

 ceolate, pod-like receptacles of granules as not uncommon. Mr. Turner 

 hinted at its affinity with Poli/siphoniafastigiata ,- and though there are no 

 real articulations, Dr. Greville considers it as a connecting link between 

 that plant and the Alga? Inarticulate. Its place of growth is remarkable. 

 I have gathered it abundantly at Cromer in Norfolk, growing in tufts 

 like Cladunia rangiferina, which it much resembles in ramification. 



31. Bonnemaisonia. Ag. Bonnemaisonia. 



Frond membranaceous, compressed or plane, filiform, much 

 branched, the branches pectinated with distichous cilia. Fruc- 

 tification, sessile or pedicellate capsules, containing a cluster of 

 pyriform (compound ?) seeds, fixed by their base. Grev. Alg. 

 Brit. p. 106. t. 13. — Named in honour of M. Bonncmaison, a 

 French Algologist. 



1. B. asparagoides, Ag. (Asparagus-like Bonnemaisonia) ; 

 frond compressed very mucli branched delicate ciliated with 

 distichous subulate ramuli, capsules alternating with these ramuli 

 and pedunculated. Ag. Sp. Alg. v. 1. p. 197. — Plocamium

On rocks and stones in the sea, rare ; Cornwall, Norfolk and Suffolk. 

 Bantry Bay and near Belfast. Abundant at Qnilty, Miltown Malbay, 

 Joshua Fenncll, Esq. — 0. Summer. — A delicate and very beautiful 

 plant, of a cellular texture. Mr. Harvey finds on this species a modi- 

 fication of the capsule, which appears analagous to what Dr. Greville 

 describes on Laurencia jnnnatifida as " disciform rcccjitavlcs." 



32. Laurencia. Lamour. Laurencia. 



Frond cylindrical, filiform, between gelatinous and cartila- 

 ginous, mostly yellowish or purplish-red. Fructification of two 

 kinds : — I. ovate capsules with a terminal pore, containing a 

 cluster of stalked pear-shaped seeds fixed by their base: — 2. ter- 

 nate granules imbedded in the ramuli. Grew Alg. lint. p. K>8. 

 t. 14. — Named in compliment to a French Naturalist, M. <le 

 In Laurencie. — k - All tin- species," Dr. Greville observes, "have 

 their branches either obtuse and often lobed, or set with little 

 incrassated ramuli ; and it is in these parts that the ternats 

 granules sre always imbedded.
