ACACIA. SEEDLINGS. 161 



Stem terete, green, at first faintly pilose, becoming 

 glabrous. First internode '5 to 1*5 mm.; second 1 mm. to 

 t cm.; third 3 mm. to 1 cm.; fourth 3 to 6 mm.; fifth 2 to 



4 mm.; sixth 3 to 5 mm.; seventh 3 mm. to 1 cm.; eighth 



5 mm. to 1*6 cm. 



Leaves — No. 1. Abruptly pinnate, petiole 3 to 7 mm. long, 

 green, glabrous; leaflets three pairs, oblong-lanceolate, 

 basal or largest pair up to 9 mm. long, 3 mm. broad, upper- 

 side green, underside paler, with midrib distinct, sometimes 

 raised, secondary vein showing under pocket lens; rachis 



6 mm. to 1 cm. long, green, glabrous, excurrent. 



Nos. 2 and 3. Abruptly bipinnate, petiole 7 mm. to 1*3 cm. 

 long. No. 3 sometimes channelled above and with strong 

 nerve along lower margin, excurrent; leaflets three to four 

 pairs; stipules little more than scales. 



Nos. 4 and 5. Abruptly bipinnate, petiole 1 to 1*5 cm. long, 

 vertically flattened, with prominent nerve just above lower 

 margin; leaflets four to five pairs ; rachis 7mm. to 1*5 cm., 

 glabrous, excurrent; stipules about 1 mm. long. 



Nos. 6 and 7. Abruptly bipinnate, petiole 1*7 to 4 cm. 

 long, vertically flattened, similar to Nos. 4 and 5, but with 

 one or two fine veins parallel to the prominent nerve; leaf- 

 lets four to six pairs; rachis 1 to 2*2 cm.; stipules about 

 1 mm. long, pointed. 



Nos. 8 and 9. Abruptly bipinnate, petiole 4 to 5*3 cm. 

 long, vertically flattened, 3 mm. broad, with a prominent, 

 almost central nerve from the plant-stem to the base of 

 the pinnae, giving the leaf, at a little distance away, the 

 appearance of a uninerve, but with several fine parallel 

 veins visible on closer inspection. 



Nos. 10, 11 and 12. Often abruptly bipinnate, petiole up 

 to 10 cm. long, 3*5 mm. broad, with prominent central 

 nerve and several fine veins on each side.
