In reference to observations on the effects of frost last winter, already 
reported, Mr Thomas Thomson states that the pinetum of Balgowan is 
200 feet, and that of Keillour 560 feet above the level of the sea. The 
state of the thermometer placed on the snow at Balgowan during the 
week when the frost was most severe was as follows, viz. :—Dec. 24, 1860, 
6° below zero; 25th, 3° below zero; 26th, 4° below zero; 27th at zero ; 
28th, 6° above zero; 29th, 3° above zero; 30th, 10° above zero. The 
thermometer on the north wall of the garden invariably indicated 23° 
higher. In ordinary circumstances there is no difference between these 
thermometers. : 
Various monstrosities of roses have been sent to the Botanic Garden 
this summer. At St Colm, Trinity, by Edinburgh, Mr W. A. Parker 
reported that almost all the roses were proliferous, producing numerous 
grown buds from the receptacles, and all surrounded by a common calyx. 
From Broomhall Park, Sheffield, Mr James Allan sent similar teratolo- 
gical specimens. In some of them the calyx was developed in the form 
of large leaves, like the ordinary ones of the rose.

Welwitsch on the Vegetation of the Plateau of Huilla in Benguela ; 
with Remarks by M. De Candolle,—M. Welwitsch has just finished 
a series of most peculiar journeys, having been engaged for several 
years in traversing the territories of Angola and Benguela, the climate 
of which is usually fatal to Europeans, and from which we have not as 
yet received any important collection of plants. He has sent a letter 
on the subject to M. De Candolle, which has been published in the 
‘¢ Bibliotheque Universelle” of Geneva for July 1861. 
M, Welwitsch says,—‘‘ At Benguela, 12°-13° Lat. 8., we begin by 
finding Zygophyllacew, Loranthacew, and Sesamew in great quantity. 
On the banks of the streams, the small tree Herminiera Elaphroxylum 
is not rare. The Acacias and Capparids become more common; a species 
of Cressa and the Salsolee appear in the saline marshes. Around Mossa- 
medes we see a Tamarix (TI. senegalensis?) very abundant. It is a 
small tree, and bears on it a Cassytha ; a species of Hydnora grows on a 
leafless Euphorbia ; several Phytolaccacew (Limewm, Gisekia, &e.) live 
on the Zygophyllacee, two Mesembryanthemums, a Vogetia, and several 
species of Sesuvium on the moving sands. More to the south, towards 
Cape Frio, Lat. 15° 40’ S., I have found, over nine geographical miles 
of coast, a beautiful Hyphene, which is probably my only new Palm. 
In the elevated sandy region occurs the new dwarf tree which I have 
called Tumboa, and which is probably the type of a new family, and 
which has affinities in structure with Conifere, Caswarinew, and Proteacec. 
Near Mossamedes (Lat. 15° S.), in the interior, there are calcareous 
mountains covered in part with Acacias and Capparidacew. Over sixty
