MARTIUS ON THE BOTANY OF BRAZIL. 25 



furtlier been perpetuated by the establisliing of the Genus 

 Beyrichia, among Schropknlarinece. 



At the same period as Mr Bey rich, Baron Von Kar- 

 winski visited Rio de Janeiro, and formed a collection in the 

 Organ Mountains, which has since passed into the hands of 

 Von Martins. Mr Von LangsdorfF at this time, by com- 

 mand of the Imperial Russian government, now prepared for 

 a very extensive journey, which was to extend to the most 

 distant territory of the Brazils ; but respecting the results of 

 it, little seems to be known, and LangsdorfF himself came to 

 Europe, in a very indifferent state of health. Accompanied 

 by Mr Riedel, an able Botanist, by Mr Tanney a botanical 

 draughtsman, M. Menetrier, as Zoologist, and Mr Rubzow, 

 as astronomer, he first went to Cuyaba, then to Mato G rosso, 

 and lastly down the Madeira and Amazon Rivers to Para. 

 Although the life of the artist was sacrificed, and that the 

 party suffered various misfortunes, the expedition yielded 

 an abundant harvest of plants, which together with many 

 former collections sent to the Imperial Garden and the Aca- 

 demy of Sciences at Petersburgh, have made the northern 

 imperial city one of the richest in Brazilian Natural History. 

 Thanks also to the great industry of her Botanists, we possess, 

 besides many others from the same quarter, the following 

 valuable additions to our knowledge of Brazilian vegetation : 

 — " Bongard, Essai monographique sur les especes d' Eriocaulon 

 du Bresii;' in the " Mem. de VAcad. de St Peter sb. 1831,"— 

 and the same author's " Generis Lacis Revisio^ adnexa Phi- 

 locrenef gen. e Podostemearnm ordine novo." Mr R. Bongard 

 has also described several species of the Genera Bauhinia and 

 Paidetia. Trinius, in his great work on Grasses, has made 

 use of all the remarkable additions of this difficult family 

 which the Brazils yield so abundantly. Dr Von Fischer, too, 

 has published many of Langsdorff's discoveries, sometimes in 

 conjunction with Mr C. A. Meyer. 



Respecting another journey which took place in the south- 

 western parts of Brazil, at the same period as the above,
