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 : 



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

 2, p. 169 (1851). 



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

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



Juniperus 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 

 Bennett. 



Algse 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 orbicularis, Magn., on leaves of Zoster a, from Fintry Bay, 

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

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

 Dermocarpa violacea, Cm., on Fucus vesiculosus, from Berwick-on- 

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

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

 Aresc/iougii, Batt., on Hitnanthalia lorea, from Cumbrae. 



Monstrosity (Flower on Fruit) in Hydroeotyle vulgaris. — Being 

 on the outlook for the flower of White-rot on 10th 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 

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

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

 15th; but the stamens did not appear to be well supplied with 



pollen. 



To-day (i 8th), the flower has quite withered away. — A. Mac- 

 DONALDj 1 Hirris. 



Rare Fungi. Lactarim violascens, Fr. — This, so far as 1 am 

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