IN VABIOUS PARTS OF THE GLOBE. 155 



but, notwithstanding', their vegetation differs very much. On 

 open rocky places I observed abundance of a species of Vellozia, 

 and a little Barbacenia, which are perhaps the most northern 

 species of the tribe to which they belong, its great centre being 

 on the mountains of the Gold and Diamond district. Neither of 

 these species were in flower. Here, also, I met with a fruticose 

 species of Huphorhia^ several suttVuticose Legumiiiosce, a fine 

 heath-like Cuphea, and a prickly-leaved Aloe-like plant, which 

 throws up a flowering stem to the height of ten or twelve feet ; 

 several Compositce^ CrotalaricB ; and, in the clefts of rocks, the 

 lovely annual Gloxinia Sarmentiana, Gardn. ; Adiautum Jili- 

 forme, Gai'dn. ; two or three species of Anemia, a Sdiultesia^ 

 and a very small Eriocaulon. 



In consequence of the revolution above mentioned, I found it 

 impossible to make the journey to the westward I had originally 

 intended. Unwilling to retrace my steps, I determined to pro- 

 ceed southward to liio de Janeiro, through the great inland 

 provinces of Goyaz and Minas Geraes. The south of Piauhy 

 being also in an unsettled state, I was advised by influential per- 

 sons not to pursue this proposed journey, as I should run a great 

 risk of losing my life by so doing ; but my strong desire to pass 

 through a hitherto unexplored country determined me not to 

 listen to their advice. Till we readied Parnagoa, a small town 

 towards the southern extremity of Piauhy, our route lay through 

 an Agreste country. Although the season was far advanced, I 

 collected on this journey upwards of 200 species, not a few of 

 which are new. Among them I may mention a curious Ca- 

 homha (C Piauhyensis, Gardn.), a Drosera, several remarkable 

 Eriocaulotis, two small white-flowered species of water-lily, one 

 of them {^Nymphcea frag runs, Gardn.) with very sweet smelling 

 flowers, and the other {^Nymphcea fcetida, Gardn.) smelling 

 strongly of coal-tar ; a large Vellozia, several Gomphias and * 

 Mourvrias, some handsome Loranthacece, Jussicea sedoides, seve- 

 ral Palms, many Leguminosie, and not a few Composites. From 

 Parnagoa we went on to Santa Maria, a little beyond the south- 

 ern boundary of Piauhy, passing through a more elevated 

 country, and consequently more interesting to the botanist. 

 Here I met with many beautiful Melastomacece, Compositce, 

 and Eriocaulons ; a Dlplusodon, the most northern, perhaps, of 

 the genus ; a fine Gomphia, a Callisthene, a large Bombax, one 

 of the most handsome Cyrtopodiums I have met with in Brazil, 

 and a beautiful large leguminous tree ( Commilobium polygali- 

 folium, Benth.). 



The district of the Rio Preto, so called from a beautiful little 

 river of the same name that flows through it, is the south-west 

 portion of the long narrow province of Pernambuco, which ex-
