xin,c.3 Merrill: Flora of Loh Fau Mountain 157 



An acaulescent succulent herb, the leaves all radical, subrosu- 

 late, when fresh thick, fleshy, brittle, when dry membranaceous, 

 olivaceous, in general oblong-obovate, apex rounded, base decur- 

 rent-acuminate and usually distinctly inequilateral, both surfaces 

 rather sparingly pubescent with short hairs, the margins some- 

 what undulate-dentate ; lateral nerves 5 or 6 on each side of the 

 midrib, rather distinct; petioles up to 4 cm in length. Scapes 

 several, usually trichotomously branched, slender, each several- 

 flowered, distinctly pubescent, pendulous, up to 20 cm in length ; 

 bracts small, oblong, pubescent, about 4 mm long; pedicels 

 slender, rather densely pubescent, 4 to 8 cm long. Flowers 

 campanulate, blue-purple, 3 to 3.5 cm long. Calyx-lobes lanceo- 

 late, free to the base, pubescent, about 7 mm long. Corolla-tube 

 terete, not gibbous, gradually widened upward, 3 to 3.5 cm long, 

 the limb somewhat bilabiate, the five lobes all subequal, rounded. 

 Stamens 2 only ; filaments glabrous ; anthers about 3.5 mm wide 

 and 1.5 mm long, united. Ovary and style pubescent; stigma 

 liguliform, entire, about 2 mm long, oblique, as persistent on 

 immature fruits often slightly reflexed. Capsules linear-lanceo- 

 late, pubescent, about 2 cm long. 



Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill 10692 

 (type), Levine 15S8, August 16, 1917, gregarious on very damp cliffs in 

 deep, shaded ravines; altitude about 1,000 meters. 



This species is apparently confined to its peculiar habitat, and was 

 observed in but a few restricted places, although where found it was 

 gregarious and abundant. It grows on perpendicular cliffs, and its in- 

 florescences are pendulous; when occurring in mass and in full anthesis, 

 it is strikingly ornamental. It does not conform with the descriptions of 

 any of the known Chinese species of Chirita or Didymocarpus, and might 

 with almost equal propriety be placed in Chirita as in Didymocarpus. I 

 have placed it in the latter genus as the liguliform stigma is not at all 

 lobed.
