FIG. .631. Haltea acicularis. 

 Half nat. size. 



length and width, l'S-1'2 cm. long, and the same at the widest part, 

 tapering downwards to the radicle ; petiole '25-'5 mm. long. 



Stem erect, terete, glandular-pubes- 

 cent, pale green, becoming red, and soon 

 becoming frutescent ; 1st internode 9-12 

 mm. long ; 2nd 0-1 mm. ; 3rd and all 

 succeeding internodes very short and 

 irregular in length, from 0-4 mm. long, 

 seldom more. 



Leaves simple, entire, cauline, alter- 

 nate, exstipulate, sessile, terete or acicu- 

 lar, acute or tipped with a 'small reddish 

 spine, glabrous except in the shallow 

 furrow corresponding to the midrib be- 

 neath, where they are somewhat glandu- 

 lar-pubescent, slightly decurrent at the

 colourless points. 



Nos. 1-4 and sometimes 5. Small, subulate, acute, or the 4th 

 and 5th linear. 



No. 6 and upwards. Gradually longer, acicular. 



Hakea laurina, B. Br. 



Hypocotyl more slender than in H. acicularis, 3'3-4'5 cm. above 

 the soil. 



Cotyledons very similar to those of "H. acicularis but smaller, 

 longer in proportion and shortly petiolate, light green, opaque, with 

 faint indications of three nerves on the under side ; lamina 7-9 mm. 

 long, 6-7-5 mm. wide ; petiole semiamplexicaul, somewhat grooved 

 above, slightly convex or nearly flat beneath, -5-1 mm. long. 



Stem erect, terete, shrubby, glabrous, reddish, slightly flexuose 

 at least in the young state ; 1st internode 4-6 mm. long ; 2nd un- 

 developed ; 3rd 5-7 mrn. ; 4th 4-5 mm. 



Leaves simple, cauline, alternate (first and second opposite), ex- 

 stipulate, sessile and narrowed to the base (at least in the young 

 state), alternately, ascendingly incurvinerved, glaucous on both 

 surfaces with a sparse ascending adpressed pubescence (each hair 

 fixed by its middle) ; petioles none. 



Nos. 1 and 2. Opposite, lanceolate, acute, semiamplexicaul at 

 the base, concave above or boat-shaped, ascending or suberect. 



Nos. 3 and 4. Spathulate-oblong, acute, entire, spreading longi- 

 tudinally. 



Nos. 5-8. Oblanceolate, tapering to the base, much larger than
