GOODZA. 



1024. Leaflets generally cuneate-ovate. 



Usually tall ; racemes often with many flowers ; lower lobes 

 of the calyx semilanceolar, as long as the tube ; fruit 

 about three times as long as broad, gradually narrowed 

 at the base. G. lotifolia. 



Leaflets generally obcordate-ovate. 



Usually tall ; racemes with few or several flowers ; lower 



lobes of the calyx almost deltoid, shorter than the tube ; 



fruit hardly twice as long as broad, suddenly narrowed at 



the base. G. medicaginea. 



ZORXIA. 



1025. Leaflets two. 



Leaflets from almost ovate- to lanceolate-linear, glandular- 

 dotted ; stipules broadish, affixed above the base ; flowers 

 in spikes, much concealed by the large stipule-like 

 bracteoles ; petals yellowish ; fruit few- jointed ; seeds 

 without any appendage. Z. dipliylla. 



1026. Fruit-bearing stalklets hardly as long as the calyx, 



bent downward. 



Comparatively robust ; leaflets three together or the lowest 

 solitary, from orbicular- ovate to nearly elliptical, mostly 

 rather long, strongly venuled ; flowers small, two to each 

 bract, forming interrupted spike-like racemes ; fruit beset 

 with clinging hairlets, few-jointed. D. brachypodum. 



Fruit-bearing stalklets much longer than the calyx, 

 spreading. 



Comparatively slender, often depressed ; leaflets three 

 together, from obcordate- to narrowly lanceolar-elliptical, 

 mostly rather short, thinly venuled ; flowers very small, 

 on almost capillary soon elongated stalklets, forming 

 short racemes ; petals reddish ; fruit beset with very 

 short clinging hooked hairlets, few-jointed. 



D. varians. 

 LESFEDEZA. 



1027. Lower petals blunt, slightly incurved. 



Very slender, much beset with appressed shining hairlets ; 

 leaf-stalks quite short ; leaflets rather small, from elliptic- 

 to linear-cuneate, nearly always three together ; flowers 

 small, from two to four in each axil, some of the lower 

 without petals ; bracteoles minute ; petals pale or some- 

 what purplish or pink ; fruit very small, ovate- orbicular. 



L. cuneata.
