RUBIACE^E 



79 



shallowly grooved, often both directed to the upper side of 

 the procumbent stem, so that the cotyledons may be fully 

 exposed to light, about 1'5 

 mm. long. 



Stem herbaceous, an- 

 nual, procumbent, quad- 

 rangular ; angles obtuse, 

 smooth, glabrous, but in the 

 adult state with deflexed 

 prickles and pubescent ; pale 

 green ; 1st internode 1 cm. 

 long ; 2nd 6'5 mm. 



Leaves scabrously hairy 

 on both surfaces, subfleshy 

 in the seedling, light or 

 dark green; petioles short, 

 shallowly grooved above ; 

 stipules interpetiolar, foli- 

 aceous, equal to or smaller 

 than the leaves and 

 similar to them in most 

 particulars. 



First pair obovate, round- 

 ed, cuspidate ; stipules simi- 

 lar, slightly smaller, one 

 on each side of the stem, at 

 all events in the first three 

 pairs of leaves. 



Second and third pairs 

 similar, with stipules nearly 

 the size of the leaves. 



Ultimate leaves in pairs, 

 lanceolate, acute, hairy on 

 both surfaces ; stipules four, 



similar and about the same v m . m.-8herardia arvmrit x S . 



size as the leaves, and re- 

 volute at the margin as are the leaves, especially when dry.
