PITTOSPORE^E

surfaces, ciliate, rather persistent, with a sunk midrib and 

 obscurely reticulate, and resemble in form the leaves that follow, 

 but are very much smaller. Those of P. erioloma are five in 

 number, whorled, lanceolate, membranous, shortly petiolate, 

 pubescent and penninerved like the leaves that follow, but 

 larger. 



A type distinct from the above is exhibited by Billardiera 

 longiflora and B. fusiformis. In the former (fig. 194) the coty- 

 ledons are linear, acute, broadest above the middle, narrowed 

 to the base, but not 

 very distinctly petio- 

 late, with a scarcely 

 discernible midrib, gla- 

 brous, and 12-5-22 mm. 

 long. The seed-leaves 

 of B. fusiformis are 

 linear, acute, glabrous, 

 one-veined, sessile, and 

 about the same length 

 as those of B. longi- 

 flora.

Cotyledons linear -lan-

 narrowed to an extremely 

 short petiole, light green, 

 pubescent on the midrib 

 beneath, otherwise gla- 

 brous, slightly channelled

side, and subcarinate on the under side, with midrib only discernible, 

 about 24 mm. long, 4-5 mm. wide. 



Stem erect, terete, pubescent with adpressed hairs, deep red, 

 somewhat flexuous ; 1st internode 1'5 mm. long ; 2nd 2 mm. ; 3rd 

 3-25 mm.
