Mr Lindsay's Report on Open- Air Vegetation. 4G9 



Report on the Progress of Vegetation at the Royal Botanic 

 Garden, Edinlurgh, from July 1889 to June 1890. By 

 Egbert Lindsay, Curator. 



July 1889. — This month was, on the whole, a very favour- 

 able one. The early part was warm and dry ; grass on lawns 

 and verges had a brown appearance dviring the first week. 

 On the 7th, a good deal of rain fell, accompanied by thunder, 

 after which no more browning took place during the season. 

 Up to the middle of July the prospect of there being a really 

 good season was very hopeful indeed ; after this the outlook 

 was not so promising. 



The lowest night temperature was 38°, which occurred on 

 the 8th, and the highest was 52°, on the 14th. The lowest 

 day temperature was 51°, on the 11th ; and the highest was 

 81°, on the 31st. Eain fell on fifteen days. 



On the Rock Garden 258 species and well-marked varieties 

 came into flower during the month, as against 276 for the 

 corresponding month last year. Amongst the most interest- 

 ing were : — Astragalus alo'pecuroides, Calamintha glabella, 

 Coccuhos japonicus, Dalliharda repens, Eremurus Olgse, Galax 

 aphylla, Lithospermum petrceum, Philesia huxifolia, Sagina 

 Boydii, Symphiandra Hoffinanii, Veratrum Maackii, Veronica 

 salicornioides, &c. 



August. — The weather during August was exceedingly 

 cold and unsettled. Eain fell on twenty-one days, and all 

 outdoor work was much retarded in consequence. So very 

 unfavourable an August has not occurred for some years 

 back. The lowest night temperature was 38°, which occurred 

 on the 31st of the month ; and the highest, 55°, on the 2nd, 

 The lowest day temperature was 59°, on the 20th ; and the 

 highest 79°, on the 1st. 



On the Eock Garden 99 plants came into flower, against 

 140 during last August. Amongst the most conspicuous were : 

 — Dietes Huttoni, Gentiana Andrewsii and ornata, Stokesia 

 cyanea, Liatris elegans, Sparaxis p)endula, Senecio speciosics, 

 Pyrola rotundifoHa var. arenaria, Sheffieldia repens, &c. 



September. — This month was, on the whole, favourable ;
