Another relation to M. tenuiflora ; readily distinguished by 

 the very long corolla-tube. 



Musssenda Debeauxii sp. nov. 



Eamula novella valde complanata breviter dense ferrugineo- 

 pubescentes. Folia supra scabrida, basi truncata v. subcordata, 

 venis secundariis utrinque 8-10. Calycis lobi petaloidei petiolo 

 2-5 mm. longo, minores inter breviores lanceolati acuti acuminati 



3 mm. longi, conspicue ferruginei. Corollce tubus breviter rufo- 

 pubescens, infra medium gracillimus, insuper parum dilatatus, 

 4-3 cm. longus. 



French Congo : Muni Eiver, July, 1902, Deheaux ! 



Belated to M, angolensis, but distinct in the longer corolla, 

 scabrid leaves, and especially the ferruginous pubescence, which 

 is particularly conspicuous in the inflorescence. The branchlets 

 are fairly stout, with eUiptical leaves about 13 cm. x 6-5 cm. ; 

 apex very shortly acuminate, acute ; the veins and transverse 

 reticulation are strongly-marked on the lower side ; petioles 

 nearly 2 cm. long ; stijjules triangular, acute-acuminate, 6 mm. 

 long and 3 mm. wide at base, hiflorescence dense, bracts barely 

 5 mm. long, setose-acuminate. Petaloid lobe of calyx rather 

 tough, densely hispidulous, obovate 4 cm. x 3-5 cm., with well- 

 marked venation on the lower side, mucronate-acuminate, wedge- 

 shaped at base. CoroZ/a-limb over 1-2 cm. in diameter. 



Musssenda Gossweileri sp. nov. 



Frutex scandens, ramulis dense flavo-pubescentibus, tandem 

 glabrescentibus, cortice fusco indutis. FoUa anguste obovato-vel 

 elliptico-oblonga, 7 cm. x 3 cm. — 13 cm. x 4*7 cm., brevissime 

 acuminata utrinque acuta, supra subscabridula subtus praesertim 

 in venis pubescentia, venis secundariis utrinque 9-12, petiolo 

 7-15 mm. basin versus dilatato ; stipulcB triangulares 6 mm. x 



4 mm. acutas. CymulcB pauciflorae ; flores subsessiles, ovario 

 angastissime conico. Calycis lobi minores inter brevissimos 

 anguste triangulares acuti acuminati ca. 2 mm. longi, petaloidei 

 petiolo vix 1 cm. longo. Corollce tubus extus breviter necnon
