the very short petiole, 24-6 in. long, 2—2 in. broad, firmly membranous ;, 
midrib rather slender, deeply channelled above ; secondary nerves about 
16-25 on each side, starting more or less at right angles to the midrib, 
curved near the margin; reticulation distinct, dark brown, somewhat 
close. Flowers sessile in dense clusters at the ends of the secondary 
rays of compound contracted umbels; peduncle 4-1 in. long; primary 
rays up to } in. long; secondary rays 2-3 lin. long. Calyx 3 lin. long; 
segments broad-ovate, subacute, overlapping at the base. Corolla-tube 
searcely 14 lin. long, villous at the mouth; lobes broad-ovate, obtuse or 
subacute, 4 lin. long. Carpels connate at the very base in flower.

I have seen only the top of a flowering branch of Fischer’s specimen. Its leaves 
are much narrower and smaller than those of the Gonja plant, but they agree 
exactly in the nervation, venation, and texture; the inflorescence and flowers also 
agree.
