Single stem 9 dm. high. Leaves lanceolate, acuminate with 

 a minute mucro at the apex, gradually narrowing from the upper 

 third to the petiole, entire, glabrous, coriaceous, pale whitish be- 

 low, 18-22 cm. long, 2.3-4 cm. wide; with petioles 2.8 cm. long, 

 which are occasionally sparingly marked with small lenticels. 

 Flowers five to six in a raceme, the peduncles 3-4 cm. long, bi- 

 bracteate, the pedicels i cm. long, bracteolate above the centre, 

 glabrous. Calyx tube cylindrical, glabrous, 8 mm. long; with 

 the lobes oblong, obtuse, minutely mucronate, thin, i cm. long. 

 Corolla purple, strongly sigmoid, 6.5 cm. long, the lower lobes 

 split less than one-half the distance of the tube, 1.5-2 cm. long. 

 Staminal column adherent to the corolla for about one-third its 

 length, the upper half puberulent, as long as the corolla. Anthers 

 puberulent. Berry not seen. 



This is the first Rollandia to be reported off the island of Oahu. 

 Its arrangement of characters easily separates it from the other 

 species, while its relatively much smaller leaves give it quite a 

 different appearance in the field.
