156 J. Gr. Agardh. 



diversas sectiones ab eo referuntur. Si Ins ducentibus aliam dispo.sitionem 

 assumere opporteret, mihi quidem non liquet. 



Species tantum duas, hucusque viveutes, ab auctoribus mein« »ratas scio. 



1. Boks. nitida (Harr, in List of Friendly Islands Algce sub n:o 83) Muri.- 



Chalm. I. c. p. 816; Sond. in Ferd. Muell. Fragment. Phytogr. Austr. 

 Suppl. sub n:o 978. 



Hab. in Oceano pacifico calidiore ad Friendly Islands (Harvey!); 

 ad oras Novse Hollandioe calidioris (Edgecombe bay, fide Sonder). 



2. Böhm.? capitata (Neomeris capitata Harr, in List of Friendly Islands Algee 



sub n:o 85). 



Hab. in Oceano pacifico ad Friendly Islands (Harvey!). 



Planta stipitata, stipite cylindraceo longitudinellt planta; obovato-globosre fere 

 eequante. Structuraiu prioris suspicatus sum; ex specimine vero, cpiod dissecavi, certam 

 idaäam de structura percipere necpiivi. 



XXV. Halieoryne Harv. 



Algam, ad Loo-Choo Islands inventam, novi Generis typum jam ab 

 initio consideravit Harvey (Proceed. of the Amerie. Acad. ruf. IV. Od. 1859). 

 Hoc loco de novo Genere dixit „Alga habitu Dasyclado proxima, fructu 

 substantiaque diversa". In Indin' Generum Algarum Halieoryne inter Dasy- 

 cladnm et Neoraeridem disposita fuit. Flantam habitu quidem Dasycladi, 

 characteribus fruetificationis Polyphysae et immo Acetabulariaä propinquio- 

 rem putavi. 



Ex brevi diagnosi Harveyana constat frondem esse clavaeformem sim- 

 plicem, axi tubuloso continuo monosiphonio ramnlisque verticillatis sac- 

 catis unicellnlaribus, demnm sporiferis, constitutam. In hac froude, qua? 

 longitudine sesquipollicem vix supérat et crassitie iiennam scriptoriam 

 snperne fere sequat, dignoscere licet partem infimam, sensim denudatam, 

 stipite cylindraceo (Tah. V. fuj. 1) constantem; supra stipiteiu partem 

 quandam f'rondis clavata? tenniorem, reliquiis plus minns laceris verticil- 

 lorum jam defunetorum obsitam ; dein totam superiorem partem magis 

 incrassatam, vigentem et verticillis densis circumcirca obsitam ; et in hac 

 parte, paulisper aecuratius inspeeta, adpareat verticillorum inferiorum ra-
