 ing are annually recorded to the Society, two came into 

 flower during April, and one in May, thus completing the 

 list given on previous page. 



May. — During the month vegetation generally made good 

 progress, although there was a considerable amount of frost 

 during the first week," and cold east w4nds during the last 

 week of the month. From the 7th till the 24th a spell of 

 fine bright weather took place, during which time vegetation 

 made rapid strides. Ordinary deciduous trees and shrubs 

 developed fine luxuriant foliage, and by the end of the month 

 many of them were in blossom. Amongst those which 

 flowered best were the various species of Pyrus and Prunus, 

 Horse Chestnut, Lilac, Hawthorn, Laburnum, and Magnolia 

 purpurea. The quantity and condition of the flowers pro- 

 duced were rather above the average. Late flowering- 

 Rhododendrons and Azalea 23ontica were very well covered 

 with flowers, while Ghent Azaleas were very sparse. Bushes 

 of Erica australis and Olearia Gunniana were unusually fine; 

 both are handsome May-flowering hard}' jjlanls, not too well 

 known throughout the country. 



The thermometer was at or IjcIow the freezing point on 

 four nights, the total amount of frost being 12°, while in 

 last May 4° only were recorded. The lowest readings were — 

 on the 1st, 30°; 2nd, 25°; 4th, 32°; 5th, 29°; 21st, 33°. The 

 highest morning readings were — on the 8th, 57°; 9th, 57°; 

 16th, 60°; 17th, 60°; 24th, 59°. The lowest day tempera- 

 ture was 52°. which occurred on the 20th; and the highest, 

 74°, on the 24th of the month. 



On the Piock Garden a large number of alpine and her- 

 baceous plants were in flower ; no less than 320 species and 

 varieties came into flower during May, being 73 in excess of 

 last May. Amongst the most interesting were : — 



Andromeda fasti;,Mata. 

 Anemone alpiiia sulplmrea. 



,, narcissiflora. 



Anthyllis erinacea. 



Alyssum alpostre. 

 Androsace lanuginosa Leicht-
