46 The. Timbers of F^itish Guiana. 



Radial Section. The Pores are medium, coarse scratches, some- 

 times containing beads of gum. The Rays are fine, inconspicuous, 

 flakes. 



Tangential Section as the Radial, but the Rays need the lens, 

 being minute. 



Type Specimens. Authenticated by Bell, No. 44/2700 (all 

 Sapwood). Imp. Inst., No. 0065. Berkhout, No. 2626. 



NOTE. The leaves resemble those of Goupia glabra, but the 

 fruit to this number is that of a Caryocar. 



45. LECYTHIS (CHYTROMA) CORRUGATA. POIT. 

 Nat. Ord., MYRTACE.E. 



Synonym, ^SCHWEILERA CORRUGATA. MIERS. 



This wood is indistinguishable from that described in 27 'a. , 

 p. 135, under the name of Lecythis Ollaria Linn (not of DaGama, 

 Spruce or Veil). As Mr. Bell uses the same name for this nun.ber, 

 and as specimens which were sent to the Colonial and Indian 

 Exhibition similarly labelled are the same wood, I think it is not 

 unlikely that it has been passing under the wrong systematic 

 name, which authors have copied one from another, without verifi- 

 cation. Hence, I think that the various references given below 

 probably apply to L. Corrugata, and not, as the authors state, 

 to L. Ollaria. I give them with reservations. 



Alternative Names associated with L. Ollaria. " Kakaralli, 

 Olla de Mono " (4a) ; " Manbarklak " (3a) (not Oemanbarklak) ;

 Sapucaia-nut (Fowl-nut) in British Guiana" (22); " Sapucaia- 

 pilao in the Province of Rio de Janeiro" (21); " Barklak in 

 Dutch Guiana" (4a). Native name applied to this number by 

 Bell, " Kakeralli." Not the " Manbarklak " described by Martin- 

 Lavigne (20c), p. 130, under the name of L. longipes. Miers.

 (22). " Berkhout says that recent researches in Holland point to 

 the fact that this wood does not resist Teredo" (3). He does not,
