enne North. There is a small laboratory 

 equipped for research in physiological bot- 

 any. The herbarium and library occupy 

 the old palace of the King of Hanover, near 

 the main entrance to the garden, and they 

 are the largest and most complete in the 

 world. The herbaceous ground is planted 

 in long parallel beds and contains several 

 thousand species. The arboretum is thor- 

 oughly illustrative of all trees that will grow 

 in the open at Kew, and the shrubs are, for 

 the most part, cultivated in areas by them- 

 selves. There are numerous special fea- 

 tures, such as the rock garden, the bamboo 

 garden, and the American garden. 



The research work of Kew is principally 

 economic and taxonomic. Around it cen- 

 ter the 24 botanical gardens and botanical 

 stations of the British colonies, which are 

 manned chiefly by men who have studied 

 or worked at Kew. The principal publica- 

 tions at present emanating from Kew are : 



1. The Kew Bulletin of Miscellaneous 

 Information. 



2. Hooker's Icones Plantarum. 



3. The Continuation of Hooker's Flora 

 of India. 



4. The Continuation of the Flora of 

 Tropical Africa. 



5. Annual Eeports. 



6. The Index Kewensis. 



The monographs and separate writings of 

 its staff of scientific men are too numerous 

 to review at this point. 



3. The E-oyal Botanical Garden of Berlin 

 is situated in the southwestern part of 

 the city, but a project for moving it out 

 into the country is now being seriously 

 considered. The palm house reaches a 

 height of about 90 feet, being the high- 

 est one yet constructed, and too high 

 for satisfactory operation. The botani- 

 cal museum is very extensive and has 

 series of economic, systematic and archgeo- 

 logical collections. The herbarium is one 

 of the largest in the world. The systematic 



beds are arranged on a strictly modern 

 sequence, and portions of the garden are 

 devoted to plant geography and plant 

 biology. The arboretum is not extensive. 

 Among special features may be mentioned 

 the alpine garden and the collections of 

 Cacti. The garden is an institute of the 

 University, where the principal laboratories 

 are situated. There is also an institute of 

 plant physiology with a small separate gar- 

 den. The official publications of the Berlin 

 Garden are the ' Notizblatt ' and annual 

 reports. A series of volumes of. '■ Jahr- 

 biicher ' was issued some years ago. The 

 publications of the garden staff are volu- 

 minous and cover all lines of botanical 

 inquiry. 



4, The long- established * Jardin des 

 Plantes,' the gardens of the Museum of 

 Natural History at Paris, are situated in 

 the heart of the city, fronting on the Seine. 

 The conservatories are grouped near the 

 main museum building, at one end of the 

 grounds, are very large and contain a great 

 variety of plants. The botanical library, 

 laboratories, and the enormous herbarium 

 are in a separate older building. The sys- 

 tematic beds are arranged in rows ; owing 

 to the limited size of the area devoted to 

 them, they are much crowded, but contain 

 a splendid assortment of species. But little 

 space is given to trees ; there are, however, 

 some famous specimens. Many valuable 

 contributions to the literature of botany 

 along all its lines have emanated from this 

 grand institution for over 100 years, pub- 

 lished for the most part, in the ' Annales ' 

 and ' Archives ' of the Museum of Natural 

 History, and in the Bulletin of the Botani- 

 cal Society of France. 



5. The Botanical Garden of the Univer- 

 sity of Vienna was established about 1754 

 and is located in the heart of the city. 

 There are here very important and exten- 

 sive museums, herbaria and libraries, and 

 one large fine greenhouse. The systematic
