its flat stigmas. The length of the stamens is very variable ; in the 

 usual state they are longer than the receptacle ; but a variety (per- 

 haps the R. Randolii of the ' Flore de France ') is not unfrequent, in 

 which the filaments are as short as in ordinary R. aquatilis, and 

 the point of the fruit is less decidedly terminal than in the nor- 

 mal form. There is also a remarkably slender, much-branched va- 

 riety, with all its parts only about a third the size they usually attain, 

 and which is almost entirely destitute of the submersed capillary leaves. 

 The species is not confined to water immediately within the influence 

 of the sea, as it also grows in a pool amongst the sand-hills between 

 Marske and Saltbura." 



Lastrea glandulosa. 



The President read the following note, also by Mr. Baker, dated 

 September 6, 1852, but declined expressing any opinion on the sub- 

 ject : — 



" I enclose a few scraps of a Lastrea not unfrequent in Yorkshire, 

 which I have collected this season, in the neighbourhood of York, 

 Thirsk, and Hawnley, which I presume to be identical with the plant 

 described in the ' Phy tologist ' under the provisional name of Lastrea 

 glandulosa ; but my own observations would induce a belief that it 

 is not distinct as a species from L, multiflora, though remarkable, and 

 worthy of attention, as a curious variety or variation. In fact, I have 

 occasionally noticed fronds with their stipes so densely covered with 

 glands as to deserve the name of mealy, and others with the stipes 

 shining and polished, — typical glandulosa and typical multiflora, — 

 with gradual intermediate gradations proceeding from the same root ; 

 but usually, when any of the fronds from the root are mealy, the 

 remainder are glandular in a greater or smaller degree ; and when any 

 of the fronds from the root are decidedly eglandulose, the quantity of 

 glands on the remainder is quite inconsiderable. The mealiness is 

 not nearly so conspicuous in dried as in recent specimens. The 

 enclosed is not nearly so mealy as some I have collected, and is 

 selected merely from its size; but, if your conclusions do not coin- 

 cide with mine, I shall be happy to enclose a series in my parcel to 

 the Botanical Society next month, though my most characteristic 

 * glandulosas ' are mostly already distributed." 



Celsia cretica in Ireland. 



The President said that he had received the following communica- 

 tion, through the kindness of Dr. Balfour Baikic, of llaslar Hospital,
