ERYHGIUXK. 



1241. Erect. 



Glabrous ; radical leaves considerably longer than broad, 

 doubly or simply pinnatifid or sometimes merely indented, 

 marked by somewhat raised transverse lines, the segments 

 or lobes generally narrow ; umbels compound, capitular, 

 mostly terminal, surpassed by the outer almost spinular 

 bracts ; flowers minute. , E, rostratlim. 



Prostrate. 



Glabrous ; radical leaves much longer than broad, simply 

 pinnatifid or merely indented, the lobes generally narrow 

 and unequal ; umbels compound, capitular, mostly 

 axillary and short-stalked, much surpassed by the outer 

 almost spinular bracts ; flowers minute. 



E. vesiculosum, 



CUCURBITACEAE. 

 IVIELOTHRIA. 



1242. Leaves orbicular-cordate, short-lobed. 



Prostrate, rough from minute stiff hairlets ; lobes of leaves 

 five to seven, somewhat sinuous ; staminate and pistillate 

 flowers on the same plant, both minute, on very short 

 stalks ; anthers almost sessile ; fruit rather small, globular, 

 smooth ; seeds several. Figure 77. M. Muelleri. 



SZCYOS. 



1243. Fruit beset with barbed bristlets. 



Climbing ; leaves almost membranous, from ovate- to 

 renate-cordate in outline, angularly three- or five-lobed ; 

 flowers minute ; staminate flowers racemose, pistillate 

 flowers capitular-crowded, the stalks of either from the 

 same axis ; fruit small, almost ovate, but acute. 



S. aiigulata. 



PASSXFX.ORAE. 

 PASSZFZ.OKA. 



1244. Petals and inner side of calyx-lobes crimson. 



Nearly glabrous ; leaves of rather firm consistence, deeply 

 incised anteriorly, dark-green and wrinkled above ; the 

 lobes mostly ovate-semilanceolar ; leaf -stalks destitute of 

 glandules ; petals less than half as long as the calyx-lobes ; 

 circular inner membrane entire, beset with hairlets, 

 shorter than the outer whorl of thread-like segments.
