the basis of Brongniart’s diagnosis and discussion, and the specimens in 
the British Museum and at Strasbourg were all cut from a segment 
of a single trunk, the main part of which is now in the Museu Na- 
cional at Rio de Janeiro. The locality of the original Martius specimen, 
said to have come from between Oeirasand SdéoGoncalo d’Amarante, 
in the State of Piauhy, has been seriously questioned by Derby and 
Count Solms, and it is now thought probable that both specimens 
came from Sao Pauloor one ofthe other southern states. The genus 
is characteristic of the Permo-Carboniferous. 
A short but relatively very important contribution to Brazilian 
paleobotany is that published in 1869 by W. Carruthers describing 
the plants collected by the English engineer, Plant, from the basin of 
the Jaguaréo and the Candiotain Rio Grande doSul, not far from the 
Uruguay border. 
This paper (1) is preceded by a short description, by the col- 
lector (2), of this coal basin, the basin of the Sado Sepé, and that 
near the town of Sdo Jeronymo, all of which were regarded as Car- 
boniferous. Carruthers published three species, Mlemingites Pedrounus 
Odontopteris Plantiana and Neeggerathia obovata, and illustrated 
some very large megaspores regarded by him as sporangia of the 
Flemingttes. Precise localities were not given. Over a quarter of a 
century elapsed before the significance of the association of the three 
species then reported became apparent. Carruther’s Flemingites is now 
referred to the genus Lepidodendron, and his Olontopteris Pian tiana 
is found to be identical with an Indo-South African species of Neu- 
ropteridium. 
The following year, 1870, professor Hartt published his Geology 
and Physical Geography of Brazil (3), in which he reprinted Plant’s 
paper together with other notes furnished by Plant. Palzobotanically 
the most important of the latter is that mentioning the occurrence ‘of 
Lepidodendron and Glossopteris. In the same publication Hartt (4) 
noted the occurrence, at a point in the State of Bahia, of fragments 
resembling Asterophyllites (2?) scutigera Dawson. These may have 
been specimens of Phyllotheca. The identification by Plant of Glosso-
