In August, imim. Mi \ K Penfold distilled oil from the leaves ol this 

 species growing in the Braidwood Distri< t, N S \\ rh< oil agreed in constituents 

 and characters with those recorded above, and consisted pra< tically of lxvo-rotatorj 

 pinene and crystallised eudesmol. Phellandrenc was absenl and cineol only 

 presenl in traces, rhe yield oi oil was 1-45 pei cent. I hi crude oil had specific 

 gravity at 15 C. 0-9132; rotation 1 . refi index al 20 = 



1-483 The saponification number for the ■ md free acid was 4. A 



portion ol the oil was acetylated in the usual way. The saponification number 

 was then r.oi-8, while in the cold with two hours' contacl n was 20-8. The 

 high saponification number was largely due to the eudi smol. 



On rectification the oil commenced to distil al 151 C. Between 154 r.1 

 35 P er cent, distilled; between c6g and ego , 17 per cent, came over; between 

 tgo 268°, 7 per rent, distilled; and between 268 2go . 38 pei cent, distilled. 

 100 c.c. of the oil was then steam-distilled, and 60 pei cent, collected. The 

 remainder in the flask soon crystallised into a solid mass, and pure eudesmol 

 w ,1- prepared from this. 



On rectifying the first distillate no less than 50 ol the 60 per rent, distilled 

 between r.55 157 , principally at 156 C. This had s]><vin< gravity at 15 = 

 0-8625; at 20 = 0-8588. Specific rotation [«]„ - 50-18 , and is thus one of the 

 highest laevo-rotatory pinenes known. The pure eudesmol had specific rotation 

 [<?]„ + 27-07°, and melted at 79-80° C. 



2L Eucalyptus alpina. 



(Lindl. Mitch., Three Exp., II, 175. 18 | 



Systematic. — A stunted tree or shrub; branchlets stout, rugose. Normal 

 leaves on thick petiole, from broad oblong lanceolate to roundish, thick, 

 coriaceous; intramarginal vein well removed from the edge; venation oblique. 

 Oil glands not prominent. Flowers sessile in the axils, from one to five together. 

 Buds about 5 lines long, warty-rough; operculum irregularly semi-ovate, or 

 semi-globular. Calyx tube nearly hemispherical, as long or slightly longer than 

 the lid. 



Fruits. Broad, almosl hemispherical, 1 omparati\ elj 

 large when lull grown (as shown m accom 

 panying plate, sometimes ribbed; run 

 broad, convex, highlj domed, slightlj con
