18. L. humistratus Greene (pi. 74, figs. 21-27). Clo.sely resembling 

 L. subpinnatus Lag. in general habit and appearance, distinguishable 

 from it by a denser villous pubescence, by the longer calyx teeth 

 (usualty twice as long as the calyx tube) and by the shorter pod; 

 ovary similar to that of L. denticidatus Greene; legumes commonly 

 straw-color, 7 to 10 mm. long, 3 mm. wide; seeds 2 to 5 (mostly 3), 

 in shape resembling those of the two preceding species.
