1 5-20 rather distant slightly ascending lepidote branches, the lowest 

 about 3 in. long, each bearing 3-7 cymes; cymes 3-7-flowered, on 

 lepidote peduncles 1 J-2J lin. long ; bracts ovate-lanceolate, lepidote, 

 very small ; pedicels lepidote, 2-2J lin. long. Calyx globose in bud^ 

 3-4 lin. wide, densely lepidote, at length 2-3-valved. Petals T), or 

 sometimes G, white, orbicular, glabrous, contorted-imbricate, the first 

 petal quite outside, the last quite inside. Stamens usually 27-30, 

 occasionally in 6-petaled flowers more numerous ; filaments free, 

 glabrous, about thrice as long as the anthers; anthers erect in bud, 

 dorsifixed, 2-celled ; cells parallel, introrse, dehiscence longitudinal. 

 Receptacular glands as many as the stamens, alternate with the 

 filaments of the outer series and mixed with the others all over the 

 convex receptacle ; glands resembling abortive sessile anthers, keeled 

 on the back below, hirsute with stellate hairs on their inner face and 

 minutely emarginate at the tip. Rudimentary ovary 0. Female

Dr. Pax has already pointed out the difficulties attending the reference of this 

 plant to Crotonoffi/ne, with which it only agrees as regards its lepidote indumentum ; 

 as now appears, the male petals of Crotonogyne are almost always united, not free a» 

 in Cyrtogonone. 



44. GBOSSEHA, Pax in Engl. Jahrb. xxxiii. 281. 



Flowers dioecious, dichlamydeous. Male : Calyx ovoid or globose, 

 closed in bud, splitting into 2, less often 3, valvate lobes. Petals 5, 

 contorted-imbricate. Stamens 17-23, several-seriate; filaments short, 

 inserted on an obovoid receptacle ; anthers dorsifixed ; cells 2, parallel, 

 introrse, connective rather broad ; base of receptacle surrounded by a 

 rino- of 5 extra-staminal glands alternate with the petals and with the 

 stamens of the lowest whorl. Rudimentary ovary 0. Female : Calyx 

 r)-lobed ; tube short-campanulate, lined at the base by the disk; lobes 

 coriaceous, orbicular, imbricate, with finely ciliate margins And a marked 

 thickened external ridge which does not reach the apex. Petals 5, 

 oblong, contorted-imbricate, much longer than the calyx. Disk cupular. 

 Ovary 3-celled, faintly 3-keeled, glabrous ; ovules in each cell solitary ; 

 styles 3, erect and closely applied in ,bud, J-partite, smooth, later 

 reflexed and with the arms slightly divaricate. Fruit a 3-coccous 

 capsule. — Shrubs. Leaves alternate, petioled, penninerved, with 2 

 prominent glands at the point of junction with the petiole, margins 

 subentire or denticulate. Flowers small or very small, in ample 

 panicles at the ends of the branches; bracts and ■ bracteoles small. — •
