462 FLORA NIGRITIANA. 
pinnata. Racemi 3-4-pollicares, ad apices ramorum solitarii 
v. plures paniculati. Pedicelli breves, fasciculati v. in race- 
mulos brevissimos dispositi. Calyx pollicaris, arcuatus, 
hine fissus, inde acuminatus, integer, extus tomentellus. 
Corolla bipollicaris, proportione multo angustior quam in 
S. campanulata, at forma illi propinquior quam 5S. levi, 
pallide lutea, intus sulphurea, stamina iis S. campanulate 
similia, sed fauce breviora, cum rudimento quinti. Ovarium 
disco crasso cireumdatum, biloculare, compressum, placenta 
columnari.. Stylus apice bilamellatus. Capsula bipedalis, 
plano-compressa, 5 lin. lata; loculicide dehiscens in valvulas 
2 septam nudantibus angustam, medio dilatatam in dissept- 
mentum spurium plano-suberosum valvulis parallelum, cap- 
sulam in loculos spurios 4 dividens, utrinque percursum 
nervo longitudinali (septa vera) seminifero. Semina more 
. plerumque Bignoniacearum plana, transverse oblonga, sub- 
quadrata, 2} lin. longa, alis neglectis 5 lin. lata; testa ad 
margines lineamque centralem calloso-incrassata, iu disco 
tenuior, ad utramque latus expansa in alam membranaceam 
5-6 lin. longam; membrana interna testa multo minor, 
tenuis et viridis, embryone conformis, nisi ad basin ubi cuneata 
est radiculam includens, apice sphacelata. Embryo planus, 
24 lin. latus; cotyledones didym:e (forma fere fructus Biscu- 
telle), apice leviter, basi profunde emarginate, radicula ex 
emarginaturze recta, } lin. longa, ad hilum spectans. 
lam not aware whether the membrane which closely enve- 
lopes the embryo is universal in Bignoniacee, as it does not 
appear to have been usually noticed. I find it, however, 1n 
Bignonia venusta, B. tubiflora, and two or three others, of which 
I happen to have ripe seeds. It always includes the whole of 
the radicle, so as to make that part appear much shorter than 1t 
really is. 
3. Spathodea tomentosa, Benth.; foliis oppositis, foliolis ap 
ovatis oblongisve acuminatis integerrimis supra glabris subtus 
ferrugineo-tomentosis, racemis terminalibus tomentosis, corolla 
glabra.—From Vogel's collection, without the precise locality, 
probably Fernando Po.
