NATURAL HISTORY OF PLANTS. 



Oxyhaphtts roseus. 



■0^ 





It is this which gives the generic name to these plants, of which 



two species are found in New Mexico. 



OccybaphvJ (figs. 11, 12) also only differs from the Marvel of Pern 



in details of form and in the number of 

 stamens. The gamophyllus and quinquefid 

 involucre is one-flowered in half the species, 

 three-flowered in the other half. 9 The peri- 

 anth lias a short tube, and expands rapidly 

 into a campanulate limb, regular or slightly 

 irregular, folded and caducous. The androceum 

 is formed of three, more rarely four, stamens, 3 

 often quite protruding on one side of the ex- 

 panded flower, like the style, which is termi- 

 nated by a stigmatiferous head (fig. 11). The 



involucre persists and often becomes membranous and veined round 



the fruit (fig. 12), which is analogous to that 

 of Mirabilis. This genus is formed of fifteen 

 species,' for the most part American ; one of 

 them however is found in the hilly regions 

 of Eastern India. These are herbs whose 

 vegetative organs are analogous to those of 

 Mirabilis, and whose small flowers are united 

 into uniparous cymes. In Western America, 

 from Mexico to Chili, a plant is found, analo- 

 gous to Oxijbcqjhus in aspect, and which is 

 named Allionia incamata. 5 Its flowers, three in 

 number, are placed in an involucre, formed of 

 three bracts, to which they are superposed.

with short spines in O. viscosus Lnfett. ; and 

 that of O. nyctagincus Sweet, is like that of 

 Mirabilis.
