Nyctaginaceae (EP., BH.}. Dicots. (Archichl. Centrospermae ; Cur-

 shrubs or herbs with opp. (often unequal) 1. and no slips. Fls. in 

 cymes, $ or unisexual, and with much variety. At the base of the fls. 

 are usu. several bracts, often large and coloured. In Bougainvillaea 

 3 large conspicuous bracts enclose a group of 3 fls. In Abronia the 

 number of bracts and fls. is larger, while in Mirabilis there is only one 

 fl. and the involucre resembles a calyx. P usu. (5), petaloid, peisistent 

 upon the ripe fr. ; usu. the upper part drops away and the fr. remains 

 in the lower part, which is termed the anthocarp, and may become 

 glandular, or form an umbrella-like wing, or otherwise serve for seed- 

 dispersal. A typically 5, alt. with the P, but often 3, 8, 10 or other 

 numbers, or raised to -20 or 30 by branching; filaments often of un- 

 equal length ; G i, with long style and i basal erect ana-campylotr. ov. 

 Achene enclosed in the P. The N. are of slight economic value ; 

 see Mirabilis, Neea, &c. Chief genera: Mirabilis, Bougainvillaea,

 on the surface ; it is nearly circular, entire, and leathery, with stomata, 

 cuticle and palisade tissue on the upper side. 



Fl. 5 , reg., acyclic ; floats on the surface. The 4 outermost floral 1. 

 exhibit a peculiar aestivation, the ant. being entirely outside, the post.
