1. Pinus Tae'Da, Loblolly, Old Field Or Frankincense Pine

Pinus Tae'Da, Loblolly, Old Field Or Frankincense Pine. Delaware, Florida, thence Texas, Arkansas. Grows along with P. palustris, and like it is a large tree, 18-30 M. (60-100°) high, but leaves (15-25 Cm.; 6-10' long) and cones (7.5-12.5 Cm.; 3-5' long) are smaller. This yields not near so great a per cent. of oleoresin as official plant, but one quite as good, consequently it is utilized for this and other purposes.

2. P. syhes'tris, Wild Pine, Scotch Fir. - Europe. Tree 21-24 M. (70-80°) high, leaves and cones only 5-7.5 Cm. (2-3') long; this yields much of the common European turpentine; P. Pinaster (P. marit'ima), S. Europe, much used for obtaining turpentine, pitch, and tar; P. Stro'bus, Pinus Alba; the dried inner bark; syrup comp.; syrup comp. with morphine.

3. Lar'ix Larix (L. europae'a, Pinus Larix), Venice Turpentine (Terebinthina Laricis - Veneta). - Obtained from heartwood by bore holes; yellowish-green, transparent, fluorescent, odor terebinthinate, balsamic, soluble in alcohol; petroxolin, 20 p. c.

4. Pini'Tes Succin'Ifer (Pi'Cea Succinif'Era), Succinum (Amber)

Pini'Tes Succin'Ifer (Pi'Cea Succinif'Era), Succinum (Amber). A fossil resin, official 1820-1860; Baltic Sea, Prussia, coal mines. There are 50 Pinaceae species that yield this resin. Such trees have been submerged under seawater, and from time to time yield by natural exudation this oleoresin, which is found along shores under and above water in irregular-sized pieces, that of 13 pounds (6 Kg.) being, so far, the largest; it is rough, dull, hard, brittle, fracture conchoidal, glossy, transparent, yellowish-red, sp. gr. 1.09, aromatic when heated, tasteless, melts at 288° C. (550° F.), yielding succinic acid, if heated higher get water, volatile acids, empyreumatic oil; contains succinic acid, C4H6O4, several resins. Used for preparing succinic acid and (empyreumatic) oil of amber, for fumigation, in the arts. Oleum Succini, official 1820-1860. Oleum Succini Rectificatum, official 1820-1890. Used as stimulant antispasmodic, diuretic for hysteria, whooping-cough, infantile convulsions, intestinal irritation, amenorrhoea. Externally - rheumatism, rubefacient liniments. Dose, v-15 (.3-1 Ml. (Cc.)).

5. Tsu'Ga (Ab'Ies) Canaden'Sis, Pix Canadensis (Canada Pitch, Hemlock Pitch)

Tsu'Ga (Ab'Ies) Canaden'Sis, Pix Canadensis (Canada Pitch, Hemlock Pitch). Prepared resinous exudation, official 1840-1890; N. America. Hemlock spruce is an evergreen tree 18-24 M. (60-80°) high, .6-1 M. (2-3°) thick, trunk straight, uniform size for 12-15 M. (40-50°), bark rough, leaves 18 Mm. (3/4') long, 2 Mm. (1/12') wide, in 2 rows, numerous, glaucous, silvery beneath, cones ovate, 2.5 Cm. (1') long, resin (oleoresin) reddish-brown, translucent, or opaque, nearly hard, brittle, fracture shining, conchoidal; odor mild, balsamic, terebinthinate. Oleoresin is obtained by exudation, incision, or boxing; yield small. Used as stimulant, irritant, in plasters. Emplastrum Picis Canadensis, official 1860-1890.
