surface ; leaves J in. wide occur in some examples, and the uppermost 

 woolly leaves are always wider, sometimes elliptic-lanceolate. Heads 

 many, axillary, scattered throughout the middle of the branches, up to 

 1^ in. long and broad, obconoid. Sepals 5, J in. long, ending in bristles 

 ^ in. long and upwards, without long white hairs ; otherwise as 

 L. spai'siceps.

Var. latifolia, C. B. Clarke. Stems hairy to the base. Leaves all hairy, broader, 

 up to \\ by 3 in., subsessile, rounded at the base, 3-nerved or some 5-nerved.

11. L. longisepala, C. B. Clarke. Branches and mature leaves 

 nearly glabrous. Leaves 2| by \ in., o-nerved to the tip, with trans- 

 verse cystoliths on the upper surface. Head 2 in. in diam., globose, in 

 an upper axil. Calyx 1 in. long ; posticous sepal having a lamina h by 

 J in. with a linear woolly hairy point J in. long. Corolla hardly | in. 

 long. Stamens 4 ; (in all 4) cells of anthers 2, oblong, muticous, parallel, 

 one slightly lower, with a row of papillje fringing the slit (as usual in 

 Eu-Lepidagathis) ; pollen small, tetrahedral, smooth with very slender 

 simple reticulations. Pistil glabrous, altogether as of the genus. 



Mozamb. Sist. British Central Africa : Urungu ; Fwambo, 5250 ft., Nutt ! 



The pollen is remote from anything seen in Lepidagathis ; I have examined it in 

 5 or 6 flowers and believe it to be abnormal, sterile. I have found one or two grains 

 not unlike the pollen of the preceding species. 



12. Ij. perglabra, C. B. Clarke. Very glabrous, margins of the 

 floral leaves with a few white long hairs. Branch 20 in. long, divided, 

 very straight. Leaves 3J by \ in., ;^>-nerved, with transverse cystoliths 

 on the upper surface. Heads numerous, scattered, axillary in the upper 

 part of the branches, very young.

This is totally different from the other part of Schweinfurthy 4076, in Herb. Kew. 

 (=:X. Medusa, S. Moore); the mixture is " noted " to have taken place before the 

 two plants arrived at Kew. The present plant has very young heads, but is very 

 distinct in habit. 



IB. L. fimbriata, C. B. Clarke. Branches and linear leaves nearly 

 glabrous. Inflorescences in the upper axils subglobose, 1-H in. in diam., 

 compound, very dense, with many numerous tine brown, scarcely hairy 

 or prickly, slender curved points to the floral leaves. Sepals 5 ; posticous 

 J in. long, obovate-quadrate, tip depressed-triangular, with a dense row 

 of white hairs below the tip ; mucro ^V ^^- ^^ng, tine brown, microscopi- 

 cally scabrous ; 2 anticous sepals nearly as the posticous but smaller ; 

 2 interior sepals slightly longer than the posticous, oblanceolate with 

 fringed shoulders and a scabrous mucro. Capsule J in. long, 4 -seeded.
