198 BOTANICAL INFOUMATION. 



genera. Oleandra neriiformis is a very peculiar fern, differ- 

 ing from the rest of the genus by having what may be termed 

 an erect frutescent branching rhizoma or caudex which is 

 hollow, about half an inch in diameter, and rising to the 

 height of from 4 to 6 feet, producing the simple fronds 

 (which are about a foot in height,) in verticillate terminal 

 tufts or lateral branches. It inhabits open situations, grow- 

 ing in groups. 



IIL—BOTANICAL INFORMATION. 



BRAZILIAN COLLECTIONS. 

 M. p. Claussen is about to leave England for a further 

 investigation of the Botany of the interior provinces of Bra- 

 zil, and now invites subscribers to send their names and en- 

 gagements to take sets of his prospective collections of dried 

 plants. 



The price has been fixed at £2 per 100 species, which will 

 include all expenses of freight, charges, &c. &c. ; so that they 

 will be delivered in London at the small cost of £2 per hun- 

 dred, without the addition of any extra expense whatever. 



An inspection of P. Claussen's former Botanical collec- 

 tions, made during a residence and researches of many years 

 in Brazil, is recommended to those Botanists who are dis- 

 posed to take sets, that they may judge for themselves of his 

 capabilities as a Botanical collector. As some proof of the 

 value and extent of his former Brazilian herbaria, it may be 

 suflBcient to mention, that of the genus Eriocavlon alone, 

 above forty species were included therein. 



The payment for these collections will be only required on 

 delivery of the respective portions, as they are transmitted 

 from the collector, so that no risk whatever will be incurred 

 by those who are willing to support the undertaking. 



Mons. P, Claussen will, as much as possible, study to avoid 

 the route pursued by former collectors, so that, as far as can. 

 be, an entirely different set of plants will be obtained.
