120. Didymochlamys Hook, f.^ — Flowers spuriously capitate; 

 receptacle obconical. Folioles of 5-partite calyx subunequally lan- 

 ceolate acuminate. Corolla tubular- campanulate ; tube having a ring 

 of hairs within ; throat glabrous ; lobes of limb 6, very induplicate 

 and introflexed undulate at margins. Stamens 5, inserted at base of 

 corolla tube; filaments very unequal "(2 longer); anthers introrse 

 dorsifixed at base apiculate enclosed, 2-rimose. Germen 2-celled; 

 disk short-conical; style slender clava,te at 2-dentate stigmatose 

 apex. Ovules oo , inserted on rather thick ascending placentas. 

 Fruit . . . ? — A low glabrous herb ; leaves alternate, 2-stichous, obhque 

 lanceolate acuminate " rather fleshy ;" petiole short; stipules " 2- 

 form; some minute clawlike bulbous at base, inserted at base of

 persistent. Lobes of funnel-shaped campanulate corolla 4-6, valvate 

 or more or less reduplicate. Stamens as many, inserted at greater 

 or less height in tube ; filaments sometimes viUose, more or less 

 unequal; anthers more or less highly dorsifixed, introrsely. 2-rimose, 

 enclosed, or exserted. Germen 2-celled ; cells complete or incomplete ; 

 disk epigynous orbicular or shortly cupular; branches or lobes of
