descending. Legume of variable form; in some cases straight 
tortuous or subfalcate, thick, spongy or coriaceous, subcarnose, 
indehiscent or tardily 2-valved (Libidibia, Peltophorum, Coul- 
teria), resinous subtorulose (Balsamocarpon) ; sutures sometimes 
thickened (Cinelidocarpus) ; in other cases legume 2-valved, 
thin coriaceous, sprinkled with glands or short bristles (Hrythro- 
stemon, Hoffmanseggia, Pomaria), straight or faleate; or else eglan- 
dular (Cesalpinaria), ovate or oblong, unarmed (WVugaria), more 
rarely somewhat turgid echinate (@uilandina), or broadly falcate or 
straight with truncate apex and coriaceous valves (Sappania). Seeds 
few or solitary, ovate obovate orbicular globose or ovoid; testa 
coriaceous; embryo exalbuminous; cotyledons flat or cordate; 
radicle short straight.—Trees or shrubs, more rarely undershrubs or 
herbs (Hoffmanseggia), either unarmed (Cowlteria, Casalpinaria, 
Libidibia, Erythrostemon), or glandular (Pomaria, Balsamocarpon), or 
prickly, high climbing (Cinclidocarpus, Guilandina, Nugaria, Sap- 
pania); leaves alternate, 2- or more rarely simply-pinnate (Parv- 
pinnaria, Cenostigma) ; leaflets rather large, coriaceous or herbaceous, 
or small numerous; stipules of variable form; flowers in simple, 
axillary or terminal, and in branching racemes; bracts small or 
large, usually very caducous (AU hot regions). See p. 71. 
3. Zuccagnia Cav.—Flowers small (of Cesalpinia) ; ovary shortly 
stipitate, 1-ovulate; style filiform, rather thick ; stigma terminal con- 
cave, minutely ciliate. Legume short subovate, 2-valved; valves 
covered with long bristles; seed descending ovate flat; embryo 
exalbuminous; cotyledons broad flat, cordate at base; radicle 
straight short.—A glutinous shrub; leaves alternate pinnate; 
leaflets small coriaceous ; stipules minute caducous; flowers in 
terminal racemes; bracts very caducous (Andine Chili). See 
p. 76. 
4, Parkinsonia Prum.—Flowers of Cesalpinia ; ovary «-ovulate ; 
style slender; apex evenly or obliquely truncated. Legume linear 
torulose, indehiscent or sub-2-valved ; valves rather thick, or thin 
coriaceous, convex over the seeds, often constricted between 
them, striated. Seeds oblong: albuminous.—Trees ; leaves alternate 
2-pinnate ; petiole short spiniform ; pinne 2-4, flattened, o-foliolate; 
stipules small, often spinescent; flowers in axillary racemes ; bracts’
