was frequently topped) ; girth, 5 inches. All the leaves 

 and branches killed ; the collar also a good deal cracked 

 by the frost. It has developed flower-buds ; but some- 

 how they have not opened.- If the collar were even 

 slightly covered, this gum would be perfectly hardy in 

 Arran. 



This is an exquisite tree, very beautiful and delicate- 

 looking. The stem, as the name denotes, is very slender, 

 the leaves small, of a pinky-blue shade, rendered more 

 lovely by a slight bloom. The stem is milk-white, 

 specially when the old bark is newly shed. It is thus a 

 White Gum. It is thus one of the slowest in girth- 

 growth of all the eucalypts. It has increased in girth 

 little more than half an inch yearly. " It grows to the 

 height of 50 to 80 feet. Bees and honey-sucking birds 

 delight in its flowers." — Mueller. 



X, Eucalyptus vi.mixalis (Manna Gum). 



Cromla, Corrie. Planted 1871. Height, 40 feet ; 

 girth, 2 feet 7h inches. Bloomed in 1886 and subsequent 

 years. See hg. in (lard. Chron., 24th Xov. 1888. 



This was the oldest of all the Arran gums. It proved 

 hardy till last winter, when to my surprise it w^as killed to 

 within three feet of the ground. It afterwards died. 

 The mountain variety probably would have been un- 

 injured. In my paper of 1886 this species is mentioned 

 under the name U. ami/r/dalina rcgnans, the packet of seed 

 having been misnamed. " This is the only species of gum 

 which yields copiously melitose manna." — Mueller. 



XI. Eucalyptus amygdalina (xllmond-leaved Gum or 

 Brown Peppermint Tree). 



1. Lochhournhead. Eaised from seed in 1890. "All 

 killed by winter of 1894-95, except one growing in a 

 gorge which was cut to the ground." — Birkbeck. 



2. Cromla, Corrie. Planted 1894. Survived the 

 following winter, but having lost all its leaves and twigs, 

 it was pulled up by a person who thought it to be dead. 



This is the most graceful of the eucalypts. The 

 branches are weeping, the leaves small, dark green, shining, 

 narrow-lanceolate, very like those of E. strida. It is 

 " The Queen of the Arran Eucalypts." The plant was 

 given me by Eobert Birkbeck, Esq., Lochhournhead.
