depressis coh^rentibus, marginibua niveo-ciliolatis ; " coronse ex- 

 terioris " (sic injuste appellatae) foliolis in tubum brevem cupuli- 

 formem truncatum connatis, gynostegium vix aequantibus, corona 

 interioris foliolis (rectiiis " coronae exterioris lobis medianis") 

 erectis anguste lineari-ligiilatis acutis, apice inflexis, gynostegium 

 plus qnam duple excedentibus glabris ; polliniis oblique ovoideo- 

 oblongis obtusissimis, caudiculis brevissimis divaricatis, glandulae 

 infra medium insertis, glandula minima rhomboidea obtusa ; stig- 

 mate generis. 



Inter frutices scandens prope ostium fluminis " Pungwe," in 

 provincia Mozambique, flor. Apr. 1895, B. Schlechter, No. 7106 ; 

 in fruticetis litoralibus insulis Mombassa, W. E. Taylor, 1895. 



A very remarkable feature in our plant is tbe tube of the 

 corolla, wbicli is inflated at the bottom, then suddenly drawn 

 together and again inflated, then again gradually drawn together, 

 and at last gradually widened towards its mouth. I collected this 

 species during my journey home at the mouth of the Pungwe 

 Eiver, in the Portuguese colony Mozambique, south of the Zambesi.

SOME NEW BRITISH MARINE ALG^. 



By E. a. L. Batters, B.A., LL.B., F.L.S. 



Several species have been added to the number of British 

 Marine Algae during the last twelve months, and the following list 

 of the new British ChlorophijceiB and Plurophycem will, 1 trust, prove 

 of interest. I hope to be able to give a list of the new Floridece in 

 an early number of this Journal. 



Chlorophyce^. 



Ochloclmte ferox Huber, Ann. Sc. Nat. ser. 7, vol. xvi. Bot. 

 p. 292, pi. X. I detected a few specimens of this interesting little 

 plant on some specimens of Clmtomurpha liniim which I gathered 

 at Cumbrae in August, 1891, and preserved in a saturated solution 

 of salt for future examination. 



Ulvella conjluens Rosenv. Groenlands Haval/j. p. 924, fig. 39. Wey- 

 mouth, on the fronds of Laminariasaccharina, April, 1892, K.A.B.; 

 April, 1895, E. M. Holmes. Dr. Rosenvinge has kindly examined 

 my specimens of this species, and he assures me that they perfectly 

 agree with the thinner specimens from Greenland, but the sporangia 

 are slightly narrower in the British plant. 



17. fucicola Rosenv. Groenl. tlavahj. p. 926, fig. 40. Heswall, 

 Cheshire, and Berwick, on Fucus vesicidosus and F. platycarpiis, 

 E.A.B. My Heswall specimens of this species are not quite 

 characteristic, as the fronds are mostly superficial, and hardly 

 penetrate the host-plant, but in all other respects they agree well 

 with Dr. Rosenvinge's figures and description of this species. Dr. 

 Rosenvinge has examined my specimens of this species also, and 

 confirms my identification.
