38 The Timbers of British Guiana. 



Bark. - in. thick, flaking off in irregular scales, very soft 

 and light; laminated and bast-liko within. Surface of log beneath 

 Bark, scored with shallow grooves. 



Uses, Qualities, etc. ' Used for the same purposes as Mora, 

 No. 65, a wood it much resembles easily procurable in logs up 

 to 30 ft., squaring 12-14 ins. Large sizes are apt to be unsound " 

 {2). My specimen does not resemble Mora. Saws easily; takes 

 nails badly, fissile. Planes and turns very badly though easily; 

 polishes well. Of little, if any, value for export.

ANATOMICAL CHARACTERS. 



The same as those of Trysil, No. 55, with the following differ- 

 ences : 



CF. No. 39 FRONTISPIECE. 



Transverse Section. Slightly darker than the other sections. 



Pores. Visible with the unaided eye, conspicuous as holes. 

 Here and there a group of many Pores (up to 15), some of which 

 are both radially and tangentially sub-divided into nests, as it 

 were. Chiefly empty; oblique lines doubtful. The linear groups 

 of small, sub-divided Pores, are unusual. 



Soft Tissue. Fine concentric lines rare. 



Radial Section. The Pores are coarse, empty grooves of the 

 same colour as the ground tissue. The Rays are just visible when 

 moistened. 



Type Specimens. Authenticated by Bell, No. 37/2693. 



38. NOT IDENTIFIED, but much like Anona Squamosa. 



^'fit. Ord., ANONACE.E. Native Name, <( HOWADANNI " (2). 



Salient Features. "A close-grained, heavy hardwood of a 

 yellow-brown colour " (2). Very dense, fine-grained, cold to the 

 ^ouch and of uniform colour. 



Physical Characters. Weight (so far recorded), 59 Ibs. per 

 cubic ft. Hardness, Grade 4, hard; compare Yew. Smell 0. 

 Taste astringent. Heartwood darkens somewhat on exposure to 

 the air. . Sharply defined from the Sapwood. Surface clean. 

 Sapwood very dark brown, much darker than the Heart; width 

 f-1 in. 



Bark. About J in. thick of three layers. The inner brown, 

 striated (or rather showing the ends of the Rays whose imprints 

 are left upon the wood within) ; the middle containing fine, white, 

 linear bodies; the outer layer is a skinny, brittle epidermis. 



Uses, Qualities, etc. "House-building not plentiful, and 

 only small trees squaring from 5-6 ins. are procurable " (2). 

 Rather hard to saw. Fissile, takes nails badly. Planes and turns 

 very hard and badly, and polishes badly. Of little, if any, export 

 value. Sometimes, confused with Irriariadanni, No. 42, and with 

 Manni-balli, No. 62, on account of the similarity of the colour of
