The above three species chemically belong to the pinene group, 

 in which E . corymhosa and the other "Blood woods" are placed. 

 But, botanical ly, they have always been considered a great deal 

 removed from the Blood woods. The seedlings bear this out. As 

 the fruits should indicate beforehand, the cotyledons are small 

 and emarginate, and the leaves are petiolate and glabrous. Stem 

 glabrous. 



E. diversicolor F.v M. (PI. xlii,, fig.6). — Cotyledons obtusely 

 oblong, emargination almost or quite absent, lamina 045 x 03, 

 petiole 0*3 cm. Leaves lanceolate then ovate, petiolate for first 

 two pairs then sessile, pale, obtuse, opposite, entire, glabrous. 

 First pr. 0-8 x 0*25, petiole 0-2; second 1-2 x 0-5, petiole 0-15: 

 third 2-5 xO-8; fourth 2*2 x 1-5 cm. First internode 0*9, second 

 1*1, third 1-1, fourth 1 cm. Stem glabrous, terete. 



E. Baeuerleni F.v.M. (PI. xliii., fig.6). — Cotyledons obtusely 

 quadrilateral, slightly emarginate, asymmetrical, lamina 0*6 x 0*3, 

 petiole 0-3 cm. Leaves petiolate, then sessile from the third 

 pair, opposite, subacute, glabrous. First pr. 0*8 xO-15, petiole 

 0-2 cm; second 1*2 xO-3, petiole 0-15; third 1-4 x 0-5 cm. First 

 internode 0-6, second 0"7, third 0*6 cm. Stem terete, glabrous. 



E.propinqua Deane & Maiden (PI. xliii., fig.4). ~ Cotyledons 

 slightly emarginate, 0*4 x 0*2, petiole 0'3 cm. Leaves opposite, 

 entire, glabrous, lanceolate, subacute, petiolate. First pr. 0-9 x 

 0-25, petiole 0'2; second 1-2 x 0-3, petiole 0-4; third l-4x0-3, 

 petiole 0*5 cm. First internode 1, second 06, third 0*6, fourth 

 0-6 cm. Stem terete, glabrous. 



E. microcorys F.v.M. (PI. xliii., fig.3; PI. Ixix., fig.l2). — Coty- 

 ledons 0*5 x0*3, petiole 0*25 cm., slightly emarginate. Leaves 

 opposite, entire, glabrous, lanceolate, acute. First pr. 0-8 x 0-3, 

 petiole 0"3; second 1 x 0*5, petiole 0-6; third 1-4 x 0*6, petiole 0-7 

 cm. First internode 1, second 0*8, third 1-1 cm. Stem terete, 

 glabrous. 



In some respects, this might be put among the "Peppermints," 

 but, on the whole, I prefer it here. One should note, however, 

 that the anthers are reniform. 



E. paniculata Sm. (PI. xliv., fig. 2). — Cotyledons small, obtusely 

 oblong, slightly emarginate, 0-3x0 15, petiole 0*2 cm. Leaves
