In this list are included the few records for Derbyshire pub- 

 lished in the Moss Exchange Club Eeports since 1902. We desire 

 to express our thanks to Mr. Ingham for the loan of these Reports. 

 Our indebtedness to Mr. Symers Macvicar's excellent Handbook

THE GENUS FLAGENIUM. 



By H. F. Wernham, B.Sc. 

 Botanical Department, Natural History Museum. 



In the course of researches into the Rubiaceous genus Sabicea 

 my attention has been called to the very similar genus Flagenium. 

 The chief distinction from Sabicea lies in the aestivation of the 

 corolla-lobes ; this is valvate in Sabicea and closely contorted in 

 Flagenium, so that the latter is included in the tribe Gardenieae, 

 in contrast with the former, a member of the Mussaendeae. The 

 ovary in Flagenium is, moreover, bilocular — a rare feature in 

 Sabicea, and the subulate-acuminate stipules of the known species 

 of Flagenium are unparallelled in Sabicea. So far as is known at 

 present, the latter is confined to Madagascar. 



The genus was established by Baillon (Bull. Soc. Linn. Paris, 

 i. 216) on Triosteum triflorum Vahl, Symb. iii. 37 (= Sabicea? 

 triflora DC. Prod. iv. 439). This is admirably figured by Drake 

 in Grandidier's Hist. Phys. Nat. Pol. Madagascar, xxxvi. vi. t. 446. 

 It is probable that Sabicea setosa Eichard, in Mem. Soc. Hist. Nat. 

 Par. v. 228 (1829), belongs to the same genus; the description 

 is unfortunately too scanty for definite decision in the matter ; but 

 the words " corolla brevissima ; antheris linearibus exsertis " 

 seem, at any rate, to exclude this plant from the genus Sabicea.^ 



Apart from this doubtful form, the genus appears to comprise 

 three distinct species, as follow : —
