The plant from Sugarloaf Mountain has irregular acute lobes ^-g in. deep towards the 

 base of the leaves ; the Cameroon plant has crenate harJlj acutely toothed leaves ; there 

 is no difference in hairiness. — Dr. Easmon notes " Odotir celerv-like, used to poison fish."

The wild specimen collected by H. H. Johnston looks separable from P. pohjspermn : 

 but the plant -rown at Kew (from seeds taken off H. H. Johnston's specimen) is much 

 more glabrous, and hardly differs from P. polijsperma, but by the rather longer capsule. 



o. P. speciosa, Hochst. in Flora 184t, PjpAU. 5. Stem quadran- 

 gular, erect, hairy upwards. Leaves long-petioled ; blade 5-() in. long, 

 ovate, unequally coarsely toothed, nearly glabrous or somewhat hairy 

 >)8neath. Inflorescence spicate, leafy, with false whorls of many flowers ; 

 flowers sub-sessile on short dichotomous axillary peduncles ; bracteoles 2, 

 very small, deciduous ; pedicels glandular-pubescent. Sepals (in fruit), 

 J in. long, linear-oblong, united for J their length, glandular-pubescent 

 without, white hairy within. Corolla-tube exceeding 1 in. long, linear. 

 Capsule J by 3^ in., glabrous, 4-G-seeded at the top and with sterile 

 ovules below ; seeds ^V in. in diam., discoid, thin, nearly glabrous on the

The corolla in Eremomastax is as in other J'uuimvilhehiiias. The pictuie of 

 Erernoinastax is correct, except that it shows no hairs.
