I. Describes the studies of nine woods: Aextoxicon punc-
tatum; Araucaria araucana; Eucryphia cordifolia; Fitzroya
cupressoides; Nothofagus dombeyi; N. obliqua; N. alpina
[N. procera]; Laurelia philippiana; and Weinmannia tri-
chosperma. Mechanical properties are presented for each
species, green and at 12 percent moisture content for static
and dynamic bending; compression parallel to grain; ten-
sion; shear; cleavage; hardness; and nail-holding properties.
II. Basic strength data are shown for the same nine species
in the green condition.

Sapotaaeae: VIII. Diploon. Res. Pap. FPL-349. Madison,
WI: U.S. Department of Agriculture, Forest Service, Forest
Products Laboratory. 4 p.
The genus Diploon is represented here by D. cuspidatum,
which is native to southeastern Brazil. Originally described
as Chrysophyllum cuspidatum by Hoehne in 1933, it was
raised to generic status by Cronquist, A. in 1946. The
anatomy of the secondary xylem substantiates this transfer.

cal Sapotaceae: IX. Pseudoxythece. Res. Pap. FPL-350.
Madison, WI: U.S. Department of Agriculture, Forest Ser-
vice, Forest Products Laboratory. 4 p.
Pseudoxythece ambelaniifolia (Sandwith) Aubreville is the
sole representative of this genus established by Aubreville
in 1972. Floristically and anatomically, its affinities are
with Neoxythece (Oxythece). Whether it can be main-
tained as a distinct taxon remains to be determined.

The genus Micropholis, originally maintained as a section of
the large pan-tropical genus Sideroxylon, was raised to the
generic status in 1891 by Pierre. The genus was adopted by
most students of the family with exception of Baehni who
reduced the various species to synonomy within his very
large and overwhelming genus Pouteria. This study of the
wood anatomy confirms the establishment of Micropholis as
a distinct entity among the American Sapotaceae.
Kukachka, B.F. 1979. Wood anatomy of the neotropical
Sapotaceae: XI. Prieurella. Res. Pap. FPL-352. Madison,
WI: U.S. Department of Agriculture, Forest Service, Forest
Products Laboratory. 8 p.
Prieurella currently consists of seven South American
species. The best known and most abundantly collected
species are P. cuneifolia (Rudge) Pierre and P. prieurii
(A.DC.) Aubr. Since 1964, five additional species have been
described by Aubreville: colombiana, lanceolata, maguirei,
manaosensis, and wurdackii. For many decades the orig-
inal species were maintained under Chrysophyllum until
Pierre established the genus Prieurella in 1891. The wood
anatomy substantiates the separation from Chrysophyllum.
Kukachka, B.F. 1979. Wood anatomy of the Neotropical
Sapotaceae: XII. Neoxythece. Res. Pap. FPL-353. Madi-
son, WI: U.S. Department of Agriculture, Forest Service,
Forest Products Laboratory. 10 p.
The genus Neoxythece consists of a small number of species
concentrated in the Amazon region and northern South
America with a single species native to the West Indies.
Anatomically and physically, the woods investigated ap-
peared to be a very closely related group. They were light
brown, very heavy, and characterized anatomically by their
narrow banded parenchyma, pores in radial/echelon ar-
rangement, abundant vascular tracheids, long vessel mem-
bers, and the presence of silica in the wood rays. Woods
of Caramuri could not be anatomically distinguished from
Neoxythece and have been included in the latter. It seems
likely that Pseudoxythece will also be reduced to synonomy.
Kukachka, B.F. 1979. Wood anatomy of the neotropical
Sapotaceae: XIII. Podoluma. Res. Pap. FPL-354. Madi-
son, WI: U.S. Department of Agriculture, Forest Service,
Forest Products Laboratory. 4 p.
The wood anatomy described here is based on the only
available specimen of the genus and is represented by
Podoluma benai from French Guiana. The specimen repre-
sents mature wood from the type tree. The wood is readily
differentiated from the other hard, heavy, and dark colored
Sapotaceae by the presence of microcrystals in the axial
parenchyma.
Kukachka, B.F. 1980. Wood anatomy of the neotropi-
cal Sapotaceae. XIV. Elaeoluma. Res. Pap. FPL-358.
Madison, WI: U.S. Department of Agriculture, Forest Ser-
vice, Forest Products Laboratory. 6 p.
The genus Elaeoluma consists of three species distributed
in the Amazon Basin, Surinam, Guyana, and Venezuela.
The description presented here is based on E. glabrescens
of the Amazon Basin. The wood is easily differentiated
from all other neotropical Sapotaceae by its pale brown
color, reticulate parenchyma, which is hardly discernible
with a hand lens, and a low relative density averaging 0.50.
