116 PHYSIOGNOMY OF PLANTS. 



Royal Herbarium at Schoneberg, near Berlin, of which he 

 is the curator, at 74000 species. 



London's useful work, Hortus Britannicus, gives an ap- 

 proximate view of all the species which are, or at no remote 

 time have been, cultivated in British gardens : the edition 

 of 1832 enumerates, including indigenous plants, exactly 

 26660 phaenogamous species. We must not confound with 

 this large number of plants which have grown or been cul- 

 tivated at any time and in any part of the whole British 

 Islands, the number of living plants which can be shewn at 

 any single moment of time in any single botanic garden. 

 In this last-named respect the Botanic Garden of Berlin has 

 long been regarded as one of the richest in Europe. The 

 fame of its extraordinary riches rested formerly only on 

 uncertain and approximate estimations, and, as my fellow- 

 labourer and friend of many years' standing, Professor 

 Kunth, has justly remarked (in manuscript notices com- 

 municated to the Gartenbau-Verein in December 1846), 

 " no real enumeration or computation could be made until 

 a systematic catalogue, based on a rigorous examination of 

 species, had been prepared. Such an enumeration has 

 given rather above 14060 species : if we deduct from this 

 number 375 cultivated Ferns, we have remaining 13685 

 phsenogamous species; among which we find 1600 Compo- 

 sitse, 1150 Leguminosse, 428 Labiatse, 370 Umbelliferse, 

 460 Orchidese, 60 Palms, and 600 Grasses and Cyperacese. 

 If we compare with these numbers those of the species 

 already described in recent works, Composite (Decandolle 

 and Walpers) about 10000 ; Leguminosre, 8070; Labiatse
