XOTES FEOM THE EOYAL BOTANIC GARDEN, EDINBURGH. 



I. Eepoet ox Tempeeatcee and Vegetation during 

 April 1894. Bj Eobekt Lindsay, Curator. 



The past month of April has been one of the most 

 favourable experienced for many years. Seldom has there 

 been so little frost in April, and vegetation has gone on 

 advancing without check. Such a fine early season rarely 

 occurs. The foliage of many deciduous trees and shrubs 

 is remarkably luxuriant and perfect. Apple, pear, cherry, 

 and currants are quite smothered with blossom. Xearly 

 all early ornamental trees and shrubs are flowering pro- 

 fusely — considerably above the average in this respect. 

 The hawthorn came into flower on the 29 th of the month, 

 much earlier than I have ever observed it before, and fully 

 three weeks before its ordinar}- time of flowering here. 

 The thermometer was at or below the freezing point on six 

 occasions, registering in all 5' of frost for the month, as 

 against 12'' for the corresponding month of last year. The 

 lowest readings occurred on the 1st, 31"; 2nd, 29'; l-lth, 

 32'; 20th, 32'; 21st, 31'. The lowest day temperature 

 was 44' on the 3rd, and the highest 72° on the 27th of 

 the month. The collective amount of frost registered this 

 season up to the end of April is 325 , as against 517' for 

 the same period last year. The following is the distribution 

 for each month: — October, IS' of frost; Xovember. oo': 

 December, 52': January, 121'; February, 63'; March, 

 63'; April, 5'. The lowest point reached this sea.son was 

 9' Fahr., or 23' of frost, which occurred on the 7th of 

 January. 



On the rock-garden 153 species and varieties came into 

 flower during the month, as against 166 for April of last 

 year. Among the more interesting were : — Anemo/u alpina, 

 A. Pulsatilla, var. Irracteoia, A. ihalictroides, Androsace 

 coronopi/olia, Arnebia echioides, AuhrietM Lekhtlini, Bry- 

 anthv.s e'rectiis, Cassiope fastigiata, Crenularia eunomioides, 

 Corydxilis Scoulerii, Cytisv.s ArdvAnii, Erythronium gigan- 

 tcv.m, Heloniopsis umhellata, Muscari Szocitzianum, Narcissus
