216 NATURAL HISTORY OF PLANTS. 
VII. DALBERGIA SERIES. 
Dalbergia (fig. 187) has irregular resupinate flowers, whose cup- 
shaped receptacle is lined by a glandular disk. The gamosepalous 
calyx divides above into five unequal teeth, imbricated in the bud. 
The two superior are the largest, and the inferior, often longer than 
the two lateral ones, is also narrower and more acute. ‘There are 
nine or ten stamens, monadelphous or diadelphous ; for the vexillary 
stamen may be quite free, united to the rest in a sheath split open 
above, or even altogether absent. The anthers 
are short erect and didymous, with their two 
cells often placed: back to back; they dehisce 
by longitudinal clefts extending all the way 
down, or only to a variable distance from the 
apex. The one-celled ovary, inserted by a short 
foot in the bottom of the receptacle, ends in an 
incurved style, with an obtuse truncate or 
slightly dilated stigmatiferous apex. Its cavity 
contains one or few descending incompletely ana- 
tropous ovules; whose micropyles look upwards 
and outwards. The fruit is dry, flattened, and 
samaroid, obliquely linear or seldom bowed, with 
a thin reticulate pericarp, one or few-seeded, 
thinned off at the edges, and somewhat swollen and thickened over the 
seeds. These are reniform compressed ; the radicle is inflexed and 
accumbent. Dalbergia contains some three-score species’ of climbing 
trees or shrubs, from all the tropical countries of Asia, Africa, 
America, and Oceania. The leaves are alternate imparipinnate ; 
with alternate leaflets (sometimes reduced to one). There are no 
stipels, but only two lateral ill-developed stipules, often caducous 
Dalbergia melanorylon.
