 Var. mftjor, Hort., is advertised. -One of the slenderest 

 of the Opuntias. It differs from other species in that 

 the fls. do not open until late in the afternoon. Several 

 forms of this plant occur throughout its range, some of 

 which have been separated as varieties. One 

 of the most frequent of the cylindrical Opun- 

 tias in cult.

OK&CH, or French Spinach, is a pot-herb cult, and 

 used much like spinach. It is an annual, grows 5-6 ft. 

 high, has furrowed stems and arrow-shaped, slightly 

 crimped Ivs. of soft texture. The inflorescence sug- 

 gests that of amarantus-like plants. The indi 

 fls. are very small, devoid of petals, and greenish or 

 reddish according to variety. For a more technical de- 

 scription, see Atriplex horiensis. 



There are three main types of Orach, based on the 

 color of the Ivs. The white variety is the one most 

 commonly grown. The Ivs. are pale green, almost yel- 

 low. The red or dark red variety has stems and foliage 

 of dark red color, which disappears in cooking. It is 

 occasionally cult, as an ornamental foliage plant under 

 the name var. atrosangiiinea. The green variety is per- 

 haps the most vigorous type. The Ivs. are rounder than 

 those of the white var. and less toothed. So far as is 

 known, only the red and white varieties are offered in 

 America. The seed is usually drilled into the open

 Bahia (see Van Deman, Kept. Dept. Agric, 188ti, p.
