6 NATURAL HISTORY OF PLANTS. 
It is this which gives the generic name to these plants, of which 
two species are found in New Mexico. 
Oxybaphus' (figs. 11, 12) also only differs from the Marvel of Peru 
Oxybaphus roseus.

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” The peri- 
anth has 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,’ 
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 
Oxybaphus viscosus.

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 Oxybaphus in aspect, and which is 
named Allionia incarnata.’ Its flowers, three in 
number, are placed in an involucre, formed of 
three bracts, to which they are superposed. 
They are tetramerous and generally tetran-
