HYBEID ORCHIDS. 

 Now that we give a figure of Messrs. Veitch and Sons' 

 recently-raised new hybrid Cypripedium, we take this 

 opportunity of enumerating some other of the more 

 remarkable Orchid-hybrids of our gardens, as — 1. 

 Phajus irroratus, a hybrid between P. grandifolius and 

 Calanthe vestita. 2. Cattleya hybrida maculata, be- 

 tween C guttata and C. intermedia. 3. Calanthe 

 Dominii, between C. masuca and C. furcata. 4.

 Calanthe vestita. 5. Cattleya Brabantise, between C. 

 Loddigesii and C. Aclandiae. 6. Cypripedium vexil- 

 larium, between C. barbatum and C. Fairrieanum.

REVIEW. 



Elementary Lessons in Botanical Geography. By J. Gr. 



Baker, F.L.S. L. Reeve and Co. 

 This excellent little manual certainly supplies an 

 acknowledged desideratum in horticultural, if not in 

 botanical science. It seems like a truism to say that 

 a knowledge of the physical conditions under which a 

 plant grows is necessary for its successful cultivation ; 

 yet so great and so general is the ignorance on this 

 point among gardeners, that to many the statement 



will not appear superfluous ; and even where the 

 ignorance is felt and acknowledged, the information 

 desired is inaccessible. Not many years ago large 

 quantities of Orchids were introduced into this country 

 and lost, for a time at least, to horticulture for want of 

 a knowledge of the simple fact that, though found in a 

 tropical latitude, they grew at an altitude which gave 

 them a temperate climate. As soon as this simple ray 

 of light entered the minds of growers and led to a 

 corresponding change of treatment, universal success 

 followed universal failure. But plant-life is affected by 

 many other circumstances besides heat. Light, moisture, 

 prevailing winds, the proximity of sea or land, the 

 degree of change in the seasons, geological formation, 

 all exercise their influence upon vegetable growth. To 

 draw attention to these, and to lead to their study and 

 to an intelligent application of the knowledge thus 

 acquired, is the object of this little book. The first 

 three chapters treat respectively of heat as affected by 

 latitude, sea or land influences, altitude. The next 

 four describe the botanical characteristics of the zones of 

 heat as intertropical, subtropical, temperate, and arctic- 

 alpine. The eighth shows the manner in which heat 

 influences the distribution of plants. The two follow- 

 ing chapters describe the distribution of atmospheric 

 moisture and the botanical characteristics of zones of 

 moisture. The eleventh treats of the influence of man 

 on the distribution of plants ; and the twelfth describes 

 the influence exercised by the physical conditions of 

 past times on plant geography. Some very curious and 

 interesting tables are given, and lists of plants illustra- 

 tive of the principles laid down. The book is written 

 in a clear and simple style, well adapted for the class 

 for whom it is intended, and we strongly recommend 

 it to all engaged or interested in plant-culture. Fol- 

 lowed up by a study of the physical characteristics of 

 the various countries of the world, it will add greatly 

 to the interest of what is too often a dreary and 

 monotonous occupation. We would not overlook the 

 educational influence which such a study is calculated 

 to exercise upon a class generally too much excluded 

 from other intellectual resources. — F. L. S.
