HARDWICKE'S SCIENCE-GOSSIP. 



85 



consisting of narrow segments ; sepals mostly white, 

 clove coloured, or silvery at the back. 



4. A. Pulsatilla (pasque flower). Plant some six 

 inches high ; silvery down over leaves, stem and 

 back of sepals, carpels feathery, sepals violet 

 pointed, bell shaped, and hardly curved back at the 

 points ; involucrum of linear downy leaflets ; leaves 

 small, delicately cut, and few in number. (We 

 believe this is figured in Weber's "Alpine Flora," 

 vol. i. as A. Halleri.) 



involucrum of 3, 5 divisions ; leaves 3 divided and 

 subdivided (a variety occurs with one flower, A. 

 monanthos). 



8. A. ranunculoides (L.). Sepals yellow ; 1-3 flowers 

 on a stem ; involucrum leaf-like ; carpels pointed. 



9. A. Baldensis (L.). Single flower ; white oval 

 sepals 6-9 ; leaflets of involucrum twice ternate, 

 leaves the same. 



10. A. sylvestris (L.). Single flower, large white 

 sepals ; leaves 5-partite ; unequally serrated. 



Fig. 65.— Anemone Halleri. (After plate in Bennett's "Alpine Plants," vol. i.) 



5. A. montana (Hoppe). Plant much larger than 

 A. Pulsatilla, of similar growth ; sepals more turned 

 back, growing 12-16 inches high ; leaves cleaner cut, 

 spreading; flowers bend down in a remarkable manner, 

 and colour is deeper than that of the pasque flower. 



6. A. Halleri (DC). Sepals lilac, about six in 

 number, spreading, not so downy on the back ; 

 prominent involucrum of broader dark green segments. 

 A strong plant, with thick stem and few leaves 

 (beautifully figured in Bennett's " Alpine Plants," 

 vol. i.). 



/8. Carpels not plumed, involucre sessile. 



7. A. narcissiflova (L.). Several white flowers in 

 a terminal cluster or umbel ; carpels glabrous ; 



11. A. nemorosa (wood anemone). Identical with 

 our English wind flower. 



12. A. hepatka (Bepatica triloba). Involucrum of 

 3 entire calyx-like divisions ; sepals blue, white or 

 pink ; leaves boldly tribobed ; each part entire ; carpels 

 pointed. 



Of A. hortensis (L.), with rose-coloured terminal 

 flower, 10-12 sepals, given by Mortier, in "Flore 

 Analytique de la Suisse," as a doubtful plant near 

 Montreux we can find nothing. 



The Physical and Chemical Laboratories of Uni- 

 versity College, Bangor, were opened by Sir William 

 Thomson on February 12. A description, with plans 

 of them, may be found in " Nature " for February 26.
