16 in. high. Leaves 4} by 1% in., ovate, acuminate at either end, 
glabrous ; petiole 4-1 in. long. Panicle terminal; floral leaves laxly 
imbricate, 4+ by + in., rhomboid-ovate, subacute; bracts } in. long, 
subulate. Sepals 5, in. long, subulate. Corolla } in. long; tube very 
slender ; lips short. Anther-cells muticous, nearly at equal height ;

3. C. (?) nuda, C. B. Clarke. Bush, 6 ft. high. Stem minutely 
and sparsely pubescent ; internodes long. Leaves 5} by 2} in., elliptic, 
acuminate, nearly glabrate, margin entire undulate, base slightly 
unequal, nearly cordate; cystoliths small on both faces; petiole $~24 in. 
long. Panicle linear, terminal, 6 by } in., closely and minutely pube- 
Scent ; floral leaves } by 1, in. ; cymes 1-4-fowered, hardly { in. long ; 
bract and bracteoles 4 in. long, linear. Sepals 5, subequal, nearly 4 in. 
long, linear, acute. Corolla 3 in. long, narrow, pubescent. Stamens 2 
filaments glabrous; anthers 2, oblong, subequal, parallel, one some- 
what above the other, ciliate at the top; pollen globose, with 12 
longitudinal equidistant ribs not reaching the pores. Style slightly 
airy towards the base. 
Lower Guinea. Gaboon: Como River, Bates, 494! 
It is worth remark that Bates, 495, where the stamens are 4 and the genus 
Filetia, is superficially extremely like this plant. 
The present plant does for Chlamydocardia, but wants the characteristic bracts. I 
think there are 6 equatorial pores to the pollen, which, further, will not do for Isoglossa, 
whether there are 6 pores or 3.
