290 NOTES ON THE GENERA 
para having two bifid or doubly concave lobes and three narrow entire 
ones with three fertile and two sterile stamens, whilst Stephanopodium 
is said to have five entire flat lobes to the corolla and five fertile sta- 
mens; this plant however is only known to me from Pceppig’s figure 
and description, and seems to require further investigation. 
The genus Tapura, which is more especially the subject of the pre- 
sent observations, although several times figured, does not appear to 
have been very accurately described. In examining Mr. Spruce's species 
for distribution, I observed that the two large divisions of the corolla 
were deeply two-lobed, each lobe being remarkably hood-shaped and 
enclosing the fertile anthers in the bud, and as I observed no indication 
of that form in the published descriptions of the other species, I gave M 
this one the name of Z. cucullata. I have since ascertained that this 
_ structure is in a great measure common to all the species of the genus, 
but as it appears to be more strongly marked in this one, I have re- 
tained the specific name under which it is distributed. 
The perigynous glands of Chailletia are, in Tapura, represented by 
a semiannular dise, either entire and enclosing at least half the ovary; 
or more or less divided into two or three lobes or glands opposite the 
divisions of the corolla, but always unilateral and incomplete. This 
dise and the bilobed diconcave divisions of the corolla are accurately 
drawn in Sir W. Hooker's figure (Icones, t. 466) of T. ciliata, although - 
neither are alluded to in Gardner's accompanying description. 
The ovary is like that of Chailletia, with two collaterally pendulous 
ovules in each cell; it is trilocular in all the species known to me, with 
a long filiform style shortly divided at the top into three oblique or re- 
curved stigmatic’ lobes; but Poeppig describes a bicarpellary species 
unknown to me, which however he only found in fruit. 
The detailed technical character of Tapura may be given as 
follows :—— 
Calyx profunde 5-fidus, laciniis ovatis concavis inzequalibus, eestivatione 
valde imbricatis, interioribus majoribus. Corolla gamopetala, irre- 
gularis, quinquefida, lobis zstivatione imbricatis; tres exteriores an- 
gusti, integri, interdum alte coaliti, 2 interiores lati, emarginati v. 
bifidi, lobis eucullato-concavis antheras fertiles in alabastro foventi- 
bus. Stamina versus apicem tubi corolla inserta et intra tubum de- 
currentia, 3 fertilia eum lobis corollze majoribus alternantia exserta, 2 
ananthera v. effceta inter lobos minores corolle sita. Discus perigy-
