cent Akena or nut bilocular disperme, outside 

 compressed discoidal rugose, 2 sides compressed 

 sulcate, edges echinate, integument thick and 

 hard, 2 oblong seeds inside. Herbaceous, leaves 

 opposite, flowers in slefider spikes — a most 

 singular N. G. with very peculiar fruit, proba- 

 bly akin to the Euphorbides, or rather Tragi- 

 DES, but the male flowers are required to ascer- 

 tain positively the natural affinities, perhaps 

 even a typical Genus if they have 4 stamens in- 

 serted on a similar calix. The name means 

 discus armed. 



741. DiscoPLis SERRATA Raf. stem weak 

 2-3chotome flexuose smooth, leaves remote pe* 

 tiolate ovate serrate acute ; spikes terminal 

 filiform, bracts oblong longer than short pedun- 

 cles. — From South Florida and Cuba, my spe- 

 cimeUiS one foot high collected by Kin, stem fus- 

 cate, leaves acute at both ends yet subdeltoid 

 and even sometime subcordate, some white 

 hairs scattered above, spikes subracemose naked 

 slender 3 to 4 inches long, with minute bracts, 

 flowers small subsessile, the^ lower ones com>-

742. Plantago multinervis Raf. Scapose,

 tenuate at both ends, remotely dentate 9 nerved; 

 scape longer sulcate hirsute, spike elongate, 

 flowers scattered or interrupted, flowers smooth, 

 calix carinate, bracts subequa) ovate acute, 

 style elongate persistent — found in Florida by 

 Kin (Col. Herb.) near to PL inierrupta which 

 differs by entire leaves, with few nerves, shorter 

 leaves and flowers, short bracts, calix not cari- 

 nate &/C . , . Here the leaves are 6 to 8 inches 

 long, nearly 2 broad, spikes 6 to 10 inches long.
