2. P. Mannii, C. B. Clarke in DC. Monogr. Ffmn. iii. 182. Young 

 parts shaggy with fulvous or greyish hair. Stems 1-9 in. long, with 

 leaves only near the base. Leaves 12-18 by 2j-4^ in., lanceolate or 

 laaceolate-obovate, acuminate at either end, when mature often nearly 

 glabrate except at the densely hairy margins. Stems J-J in. in diam.; 

 upper leaves few, up to 3J in. long, broadly lanceolate, not sheathing. 

 Inflorescence 4-7 by 1-1 J in., oblong, most dense, with several hundred 

 flowers ; bracts small, concealed by the flowers ; pedicels 0-J in. long, 

 persistent. Ovary glabrous. Fruit not known. — Durand tfe Schinz,

Upper Guinea. Fernando Po ; 3000 ft., Mann, 2340 ! Cameroons : Came- 

 roon Mountain, 2000-3000 ft., Mann, 2139! Kalbreyer, 163! 



I described this in DC. Monogr. Phan. I.e. as " caulescent," and Mann has noted 

 the herb as 2 ft. high, which probably refers to the larger leaves. The stein is as in 

 P. bracteosa ; the upper leaves are much reduced. The fruit being unknown, there 

 may be more than one species included here. The material is of 2 forms, viz. — 



a. P. Mannii, C. B. Clarke, type {i.e., Mann, n. 2340). Leaf in the type 

 specimen 20 in. long (exclusive of the long petiole), obovate, broadest very near 

 the top, suddenly narrowed into a short lanceolate tip (not an in. long). 



p. {i.e., Mann, 2139.) Leaf 16 in. long, lanceolate, broadest rather below the 

 middle, narrowed into an elongate triangular tip nearly 9 in. long, not acuminate. 

 Kalbreyer, n. 163, is nearly the same. 



3. P. Barter!, 7/oo^. /. in Bot. Mag. t 5318. Young parts shaggy 

 with fulvous or greyish hair. Stems 1-5 in. long, with leaves only near 

 their base. Leaves up to 24 by 4^ in., the blade (exclusive of the quasi- 

 petiole 8 in. long) often 9-15 in. long, obovate-lanceolate, suddenly 

 narrowed into a lanceolate tip 1 in. long, when mature often nearly glab- 

 rate except at the densely hairy margins. Leaves on the stem 1-2 in. long, 

 lanceolate, bract-like, not sheathing. Inflorescence' lJ-2 by 1-1 J in., 

 very dense, short-oblong or quadrate (but see note below on the culti- 

 vated plant) with 100-250 flowers; bracts small, concealed by the 

 flowers ; pedicels 0-J in. long, persistent. Ovary with long simple hairs 

 scattered all over. Fruit immature, 5-seeded. — C. B. Clarke in DC.

Upper Guinea. Fernando Po ; Barter ! Mann, 94 ! Cameroons : Bipinde, 

 Zenker, 1164 ! 



The plant, in continued cultivation at Kew, has developed a narrow-oblong 

 inflorescence, 4^ in. long, looser than in the wild collecUons. The P. ombrophila, 

 K. Schum., has the ovary fully as hairy n« in the picture in the Botanical Magaaine, 

 and must be conspecific with P. Barteri.

 partly. Young parts shaggy with fulvous or greyish hair. Stem 3-7 ft. 

 long, ^ in. in diam., with internodes 2-4 in. long (or more) and 2 or 3 

 leaves apparently whorled at the node. Leaves up to 26 by 8 in., and
