 bracts shorter than the flowers, dilated and 3-cleft; the lobes with petaloid yellowish tips. 



C. linoides. Stems strict, a foot high, rigid, branching at summit, very smooth, as also 

 the rigid leaves (these 1 or 2 inches long, a line or less wide) : calyx and corolla nearly of 

 C. brct-iftora, the former with narrower lobes and the latter only half inch long. Clover

31. ORTHOCARPUS, Nutt. ('O^oc, upright, and x/wr<v, fruit; the 

 capsule not oblique as in Melampyrum.) Low herbs, almost all annual (W. 

 North American and one Chilian) ; with mainly alternate entire or 3-5-parted 

 and laciniate leaves ; the upper passing into bracts of the dense spike and not 

 rarely colored, as also the calyx-lobes ; the corolla yellow, or white with purple 

 or rose-color, often much surpassing the calyx. Seeds numerous or rather few.
