DIPSACE.E 91 



The first pair of leaves are broadly oval, slightly emarginate, 

 suddenly narrowed at the base into short, channelled petioles, ob- 

 scurely alternately incurvinerved on the upper surface, bright green 

 and shining, but distinctly nerved underneath and paler, glabrous. 



On the upper side of the cotyledon, close to the edge of the sinus, 

 are about three large water-pores in connection with the vas- 

 cular system at the apex of the midrib. The smaller cells of the 

 tissue in that region seem to determine the slower rate of growth 

 resulting in the emargination of the cotyledons. 



FIG. IbO.-Scabiosa australis, x 6. Seedling, forty-four days after germination. 



Scabiosa palaestina, L. (fig. 451). 



Achcne closely surrounded and enclosed in an involucel, thin- 

 walled, membranous, pale-coloured, eight-ribbed longitudinally, 

 pubescent, produced into along slender beak or neck, expanding into 

 a short cup from which spread ten to twelve long feathery rays. 



Involucel turbinate, longitudinally eight-ribbed, perforated with 

 as many openings near the top, above which it expands into a broad, 

 nearly or quite flat, many-ribbed, scarious lamina, with the ribs 

 exserted as marginal teeth, more or less hairy. 



Seed broadly ovoid, conforming in outline to that of the achene
