194 REPORT ON THE PLANTS 
tibus, rugosis, ad nodos compressis, striatis, pallide tomentosis: 
foliis simplicibus, late ovatis, imo obtuse angustioribus et 8- 
пегүііѕ, apice rotundatis aut brevissime acuminatis, mu 
cronatis, margine sinuato-crenatis, superne planis, sparse 
puberulis, subtus pallidioribus, densius pubescentibus, præ- 
sertim in nervis venisque reticulatis; petiolo densiter pubero ; 
paniculis floribundis, terminalibus, et in axillis supremis 
enatis, calyce parvo, turbinato, margine ampliato mem- 
branaceo plicatim expanso: corolla dense purpurea infundi- 
buliformi-campanulata, lobis oblongis, rotundatis,—Proy. San 
Paólo (Weir, No. 71). 
In its inflorescence this species bears much resemblance to that 
of the Bignonia leucopogon, Cham., but it differs from the genus 
Petastoma proper, in its simple leaves. Its internodes are 1$ inch 
apart, the leaves 22 inches long, 2} inches broad, оп a petiole of 5 lines 
in length. The terminal panicle is 3 inches long, with branches 
bearing each 8 flowers; the pedicels are 1 to 1} line long: calyx 2 lines 
ong, З lines diameter in its very expanded mouth; the tube of the 
corolla is glabrous, 14 inches long (including its basal constriction of 4 
lines); the lobes of the border, 6 lines long, are externally tomentous, 
the filaments are smooth, but pilose at their origin; the anther-lobes, 
greatly divaricated, reach the mouth of the corolla ; the ovary is obso- 
letely tomentous, and sealed on a fleshy cupuliform disk. 
16. Ретазтомл (P ENEPHYLLUM) SIMPLICIFOLIUM,— Bignonia bra 
chypoda, var. platyphyllum, D.C. l.c. 146.-—Prov. San Paölo 
(Weir, No. 204). 
The genus Petastoma forms a very distinct group, of which the 
Bignonia samydoides, Cham., is the type. They are nearly all climbing 
Plants, with rather slender branches, and cirrhosely conjugate leaves, 
somewhat cordate at base, the petioles being generally much divari- 
cated. The inflorescence is in terminal or axillary panicles, with 
e the length of the calyx, and then swells into а 
rather campanulate and subventricose tube, with a somewhat 2-labiate 
expanded border, which is greatly imbricated in the bud, when its 
summit is se with a very dense white tomentum, which is very 
conspicuous; the stamens, originating in th | ietion, arch
