silky needles, m. 123 (A) and warm HN0 3 gave (C0 2 H) 2 , even when HOAc
was used as diluent. Coned. KMN0 4 also gave (C0 2 H) 2 . Fusion with 5 parts
KOH at about 250 : gave a volatile oil with the odor of AniOH. The aq.
soln. of the fusion was acidified and extd. with E-t 2 0. yielding BzOH,
isolated as the Ca salt. In another expt. the aq. soln. of the fusion
was satd. with C0 2 , shaken out with Et 2 and then with ale., which did not
mix with the soln. The ale. soln. containing K salts was evapd., acidified with
H 2 SO^, and distd. with steam. The resulting volatile acids were purified
through the Ba and Xa salts, and finally sepd. as the Ag salts. HOAc and
C H :j -C0 2 H were found. Boiled with HI for 12 hrs., (A) yields a substance, C 22
H 22 6 , faintly yellow, silky needles, m. 180-1°, changes into short rhombs
with identical properties on standing overnight in the mother-liquors when
erystd. from ale. gives a deep green color in ale. with FeCl 3 ; its methyl
derivative, prepd. with Me 2 S0 4 and aq. KOH containing a little ale. to
facilitate solu. m. 216° ; the monoacetyl derivative, using Ac 2 O and NaOAc,
m. 218-9°.— Chemical Abstracts, Aug. 10, 1915 ; p. 2061.

A slender tree with drooping branches, branchlets black. "Bark light brown, rather shining, very thin, smooth. Wood greyish white, hard: many dark concentric lines, resembling annual rings, without or with very few pores; very numerous, narrow, anastomozing white brands, in which the scanty moderate- sized pores appear. Medullary rays moderately broad, white, regular (Gamble). Leaves red. when young 2-4 in., thickly membranous, lanceolate, occasionally oblanceolate, nearly sessile, mucronate, rarely obtuse. Secondary nerves slender. 6-10 pair, a few shorter, very slender: intermediate nerves between. Flowers tetramerous, small. Sepals orbicular, outer small petals rather smaller. Male flowers: a central, round or 4-sided mass with crowded, numerous. 2-celled anthers: in terminal 3-7-flowered, often pedunculate cymes; pedicels ¼in. long. Anthers numerous, 2-celled on short filaments crowded on a
