32. TYLOPHOROPSIS, K E. Br. in Gard. Chron. ]S04, xvi. 24:>. 



Calyx 5-lobed almost to the base. Corolla deeply 5-lobed. rotate or 

 rotate-campanulate ; lobes overlapping to the left in bud. Corona of 

 5 fleshy tubercles adnate to the lower half of the staminal-coUimn, 

 alternating with the corolla-lobes, usually having 5 very minute teeth 

 alternating with them (and with the anthers) at the base of the 

 column, representing a rudimentary outer corona. Staminal -column 

 arising just above the base of the corolla; anthers erect, short and 

 broad, obtuse, with an inflexed membranous appendage at tlieir apex. 

 Pollen-masses pendulous, solitary in each anther-cell, attached in pairs 

 to the pollen-carriers by horizontal caudicles. Style not produced 

 beyond the anther-tips. Follicles smooth; seeds crowned with a tuft 

 of hairs. — Perennials with twining stems, opposite leaves, and the 

 peduncles lateral between the bases of the petioles, bearing two or 

 more sessile umbel-like cymes racemosely scattered alcJng them, flowers 

 small. 



Species 2, one a native of Arabia. This genus resembles Tylophora in every- 

 thing except that the pollen-masses are distinctly pendulous and have much stouter 

 and very different caudicles.
