164 CRYPTOGAMIA ANTARCTICA. [Puegia, the 
Haz. Hermite Island, Cape Horn, and the Falkland Islands; abundant. 
Cespites 4-5 unc. longi, basi e ramulis perplurimis implexis intricati. Rami primarii circumscriptione lineari- 
obovati, plerumque quaterni, secundarii ramulique ultimi oppositi, patentes. Utriculi semper oppositi, ramulo brac- 
tezeformi duplo longiores. 
In habit and general appearance resembling the European Z. granulosus ; but abundantly different in the 
constantly opposite sessile conical capsules or utricles, which are generally subtended by a minute ramulus half their 
own length. 
16. MESOGLOIA, 4y. 
1. MzsoerorA Zinearis, Hook. fil. et Harv.; virescens, fronde circumscriptione lineari, caule gracili 
indiviso v. rarius diviso ramis brevibus ornato, ramis alternis crebris abbreviatis flexuosis erecto-patentibus, 
ramulis subsecundis. Nobis iz Lond. Journ. Bot. vol. iv. p. 251. 
Has. Hermite Island, Cape Horn; rare. 
Frondes 4-6 unc. longi, vix 4 lin. diametro, pallide flavo-virescentes, Caulis gracilis, indivisus v. basi ter quaterve 
divisus, rarius medium versus in ramos 2 primarios fissus. Rami perplurimi, 4-4 une. longi, flexuosi, interdum 
basin versus caulis nudi v. ramulis paucis aucti. Ramuli secundarii plerumque e margine inferiore seu exteriore 
ramorum orti, Peripherie filamenta moniliformia, e substantia gelatinosa vix exserta. 
Probably the representative of the European M. vermicularis, from which it may be at once distinguished by 
the ramification. 
17. DELESSERIA, Lamourz. 
1. DELESSERIA sanguinea, Lamourx. Engl. Bot. t. 1041. 
Var. B. lancifolia; fronde elongata anguste lineari-lanceolata ligulatave utrinque angustata. 
Has. Hermite Island, Cape Horn; on rocks, abundant near the shore, also dredged up in five or 
six fathom water. 
Hitherto known only as an inhabitant of the seas of the Northern hemisphere; where its range is not wide. 
In the southern it appears to be confined to the extreme south of America, flourishing in the deep bays which indent 
the coasts of Fuegia. Some specimens are altogether similar to those of European growth; others, of which we 
have constituted the var. lancifolia are larger, longer, sometimes almost a foot long, much narrower, and more 
attenuated at both ends. It is a very handsome variety. 
2. DeLesserIa Davisii, Hook. fil. et Harv.; caule cartilagineo alato, lamina profunde pinnatifida v. 
pinnata, laciniis pinnisve cultrato-lanceolatis obliquis costatis penninerviis, nervis alternis, demum inter 
nervos alterne v. secunde lacerato-laciniatis, lacinulis erecto-patentibus costatis. Nobis in Lond. Journ. 
Bot. vol. iv. p.52. (Tas. CLXXV.) 
Has. Hermite Island, Cape Horn; abundant. Falkland Islands, Berkeley Sound, Dr. Lyall. 
Frons 5—7-uncialis, alata v. latiuscule marginata, basi in caulem brevem abrupte attenuata, circumscriptione 
late ovato-rotundata, in lacinias perplurimas simplices v. partitas distichas costatas divisa, rosea, membranacea. 
Laciniz plerumque secus marginem exteriorem oblique ad costam fisse, 1—1 unc. late, obtuse v. subacutee.—Inter 
D. alatam et D. sanguineam quasi media, sed utraque sat diversa. 
This is perhaps most closely allied to D. sanguinea, from which it may be distinguished by the alternate 
nervation and dividing of the frond. The D. alata, which it is also near, differs in the lexture and colour of its 
frond. No fruiting specimens were found.
