to the pi. In some halophytes of this fam. the 1. are altogether 

 suppressed, and the pi. has curious jointed succulent stems like a 

 miniature cactus (e.g. Salicornia). Each 'limb' embraces the next 

 succeeding one by a sort of cup at its apex. Even more than in 

 their external form, the C. show xero. structure in their internal 

 anatomy. 



Infl. often primarily racemose, but the partial infls. are always 

 cymose, at first often dich., but with a tendency to the cincinnus 

 form, by preference of the /3-bracteole. The fls. are reg., small and 

 inconspic., $ or unisex. P simple, rarely absent, persistent after 

 flowering, 5, 3, 2 (rarely i or 4) united, imbr., sepaloid ; A as 

 many as or fewer than P segments, opp. to them, hypog. or on 

 a disc; anthers bent inwards in bud; G (semi-inf. in Beta), i-loc. 

 with 2 (rarely more) stigmas; ov. i, basal, campylotropous. Fr. 

 usu. a small round nut or achene ; embryo usu. surrounding the 

 endosp., either simply bent or spirally twisted. Few are useful ; 

 see Beta, Spinacia, Chenopodium, &c.
