23. PHAYLOPSIS, Willd. ; Benth. et Hook. f. Gen. PI. ii. 1081. 



Calyx 5-fid nearly to the base; 2 anticous segments oblong or 

 linear, posticous segment ovate or elliptic, 2 inner segments shorter, 

 linear. Corolla small ; tube \ in. long or less, inflated upwards (except 

 in P. lankesterioides and P, glandulosa) ; lobes 5, contorted, nearly 

 equal, but forming 2 lips. Stamens 4 ; anther-cells at the base 

 minutely apiculate or muticous; pollen short-ellipsoid, longitudinally 

 12-ribbed, with 3 stopples. Style thinly hairy; one stigmatic arm 

 linear-oblong, the other very short ; ovary with 2 ovules in each cell, 

 glandular at the top, often also hairy or glandular nearly to the base. 

 Capsule elliptic, compressed, solid at the base, 4-seeded, margins very 

 stout, solid, faces becoming scarious and breaking up ; capsule dehiscing 

 with elasticity, the placentae (carrying the seeds) separate and spring 

 up from the bottom ; margins of seeds with numerous hygi^oscopic 

 hairs. — Small, shrubby. Leaves often very oblique, those in one 

 opposite pair unequal, elliptic, entire or crenate. Inflorescence in 

 cylindric or ovoid spikes, the broad floral leaves enclosing a contracted 

 cyme of usually 3 flowers ; bract and bracteoles 0. 



Species 15, in Africa, Mascarene Islands, India. 



Petalidum differs from Fhaylopsis little but by having 2 large bracteoles to each 

 flower. 



Willdenow constituted the genus Fhaylopsis in 1800. Bentham (in Benth. 

 et Hook. f. Gen. PI. ii. 1081), states that the genus is equal to Micranthus, Wendl. 

 published in 1798, but as the name Micranthus, Ecklon, had been for fifty years 

 used for a genus of Iridece, Bentham exercised his discretion by continuing the 

 name Fhaylopsis, though Micranthus had two years priority. In 1891, O. Kuntze 

 revived Micranthus, Wendl., after it had slept for ninety-three years.
