TRANSACTIONS AND PROCEEDINGS OF THE [Sess. lv. 



SEPTEMBER. 



September was a most favourable month, being un- 

 usually warm and dry for the time of year. No frost 

 occurred ; there was a fair amount of bright sunshine, and 

 for gardening work was all that could be desired. The 

 lowest night temperature was 38°, which occurred on the 

 1st, and the highest, 56°, on the 4th of the month. The 

 lowest day temperature was 59°, on the 31st, and the highest, 

 80°, on the 16th. 



Herbaceous plants and annuals flowered extremely well, 

 and were at their best during this month. The earlier 

 flowering kinds ripened an abundant crop of good seeds, 

 which were gathered in fine condition. 



Eoses flowered very freely during September, the blossoms 

 being equal to those developed earlier in the season. On 

 the rock-garden forty-seven plants came into flower as 

 against thirty-eight during the corresponding month last 

 year, amongst which were the following : — Andromeda japo- 

 nica, Arenaria montana, Aster sijectabilis, Crinum Moorei, 

 Crocus Imperati, C. nudiflorus, Gaidtheria numnndarifolia, 

 Geranium Wilfredii, Gladiolus Saundersii, Kniijliofia nohilis, 

 Lirutria anticaria, Palmerelia dehilis, &c.
