communis. On comparing them with specimens from Transylvania 

 and the Austrian Tyrol at Kew, it seemed to me they agreed with 

 Schur's plant. 



But I should rather place it as a variety of communis, as Nyman 

 has done, than as a hybrid, as Wettstein does ; as it fruits freely. 



It might be searched for when the two plants grow together, 

 if an hybrid. The references are : 



Junipems intermedia, Schur, in " Verh. siebund naturf. Verein," 

 2, p. 169 (1851). 



Junipems communis, L., var. intermedia. Nyman, in " Consp. Fl. 

 Europ.," 3, p. 676 (1881). 



Junipems communis x nana. Wettstein, in " Sitzb. Wien. Akad. 

 math, nat.," cl. xcvi. p. 332 (1887). 



Intermediate in habit and characters between communis and 

 nana, though perhaps nearer the former ; fruiting freely on both 

 the Austrian Tyrolese and the Hebridean specimens. ARTHUR

Algae Britanniese rariores exsieeatse, fasc. vi., issued by E. 

 M. Holmes, F.L.S. This excellent series of new, rare, and critical 

 British Algae must prove of much value to all algologists, but 

 especially to isolated students of these plants. Of the twenty-five 

 in the fasciculus now issued, the following are from Scotland : 

 Ascocyclus orbicular is, Magn., on leaves of Zostera, from Fintry Bay, 

 Cumbrae ; Ascophyllum Mackaii, var. Robertsoni, Batt., from Loch 

 Ranza, Arran ; Ctwrdaria divaricata, C. Ag., from Fairlie, Ayrshire; 

 Der/nocarpa riolacea, Crn., on Fucus resiculosus, from Berwick-on- 

 Tweed ; Lithothamnion corallioides, Crn., from Lamlash Bay, Arran; 

 L. rosaceum, Batt., M. S., from Berwick-on-Tweed ; Mesoglcea lanosa, 

 Crn., from Lamlash Bay ; Monostroma Blyttii, Wittr., from Kame's 

 Bay, Cumbrae ; Pylaiella varia, Kjellm., from Invergordon, Ross- 

 shire (see "Ann. Scot. Nat. Hist," vol. ii. p. 101); Streblonema 

 Areschougii, Batt., on Himanthalia lorea, from Cumbrae. 



Monstrosity (Flower on Fruit) in Hydroeotyle vulgaris. Being 

 on the outlook for the flower of White-rot on loth August I found 

 one plant, which bore only fruit. As there were several unopened 

 buds on the plant, it was taken home and put into a shallow vessel 

 in water where some sun-dew was growing in Sphagnum. The 

 pennywort put out new leaves from the buds, and also a single 

 flower from the tip of one of the fruits in the region of the style of 

 the former flower. The new flower was fully developed on the 

 1 5th; but the stamens did not appear to be well supplied with 

 pollen. 



To-day (i8th), the flower has quite withered away. A. MAC-

Rare Fungi. Lactarius violascens, Fr. This, so far as I am 

 aware, is new to Britain. It has been discovered on Deeside by
