to that of last, and especially if of as long continuance, 

 the plant ought to receive a little protection. From what, 

 however, this paper records regarding the increased hardi- 

 ness of eucalypts raised from Scottish seed, it may be 

 hoped that some of the tree-ferns raised at the Eoyal 

 Botanic Garden, Edinburgh, from Arran spores vdll be 

 hardier than theu- parent, and that in a third or fourth 

 generation such hardiness will be obtained, and the plants 

 will become so acclimatised that the sea-coast dells of 

 Arran will be adorned with tree-ferns well nigh as luxuriant 

 as those which now grace the islands of Xew Zealand. 



II. DiCKSONiA SQUARKOSA (Black-stemmed Tree-Fern). — 

 This plant originally grew near Canterbury, Xew Zealand. 

 In 1878, when its stem was 4 inches in height, it was 

 brought to this country, and the following year planted at 

 Cromla, Corrie. Whether from being in a colder situation 

 than the Great Tree-Fern, — for it grew in a sheltered corner 

 at the north side of the house, while the other occupies a 

 similar situation at the south, — or that the plant is itself 

 more delicate, it always suffered more from frost than the 

 other, more frequently losing its fronds. 



1894. Height of stem, 1 foot 10 inches; girth, 1 foot 

 1 1 inches. Never bore spores. Killed last winter. 



III. Cyathea dealbata (Silver Tree-Fern). Planted 

 1875. Uninjured by the following winter. "Was stolen 

 in the winter of 1876-77. 



IV. Ck'ATHEA MEDULLARis (Pithy Trec-Fem). — Planted 



1878. The following winter was decidedly severe, but, 

 protected by a heap of leaves and a heavy fall of snow, 

 the fern came up fresh in spring. The next winter was 

 very severe, and no protection of leaves having been given, 

 and there being little snow, the fern was killed. It would 

 stand if protected in winter by a heap of hedge cuttings. 



V. ToDEA SCPERBA (Moss Fern). — Planted 1879. Is in 

 good health, and with a little attention would grow 

 luxuriantly. 



VI. ToDEA HYMENOPHYLLOIDES (Filmy Moss-Fem). — 

 Planted 1879. Grew luxuriantly, but died the winter 

 before last through the crown having become bare. 



VII. Trichomaxes radicans (Killamey Fern). — Planted 



1879. Throve for manv vears. Was at length killed by
