filiform. Capsule ovoid or ellipsoid, 4-seeded from the base, or base 

 narrowed and seedless. (In honor of J. Justice, a Scotch horticulturist.) 

 Species about 250 in all tropical countries, 6 or 7 in the Philippines. 



An erect shrub 1. 3. gendarussa 



A slender, prostrate or spreading herb 2. J. procumbens 



1. J. gendarussa L. 



An erect, branched, glabrous shrub 0.8 to 1.5 m high. Leaves lanceolate, 

 acuminate, 7 to 14 cm long. Spikes terminal and in the upper axils, 4 to 

 12 cm long, the flowers clustered, the lower cluster often distant. Calyx- 

 teeth linear, about 3 mm long. Corolla 1.5 cm long, white or pink with 

 purple spots. Capsule about 12 mm long, glabrous, clavate. (Fl. Filip. 

 pi. 80, Dianthera subserrata.) 



In open waste places, hedges etc., fl. Dec.-Feb., and probably in other 

 months; widely distributed in the Philippines, certainly indigenous. India 

 to China and Malaya, often, perhaps, cultivated only. 



2. J. procumbens L. 



A slender, often tufted, prostrate or ascending, branched annual, the 

 stems 10 to 40 cm long, slightly strigose or nearly glabrous^ Leaves elliptic 

 to oblong-ovate, petioled, 1 to 2 cm long, obtuse. Spikes terminal, 1 to 5 

 cm long, about 5 mm in diameter, rather dense. Flowers pink, 6 to 7 mm 

 long, the bracts and calyx-teeth green, linear-lanceolate, hirsute. Capsule 

 slightly pubescent, about 4 mm long. 



In grass lands, Masambong, fl. Aug.-Sept.; widely distributed in the 

 Philippines. India, through Malaya to Australia.

1. Spiny plants with yellow flowers. 



2. Leaves linear-lanceolate; flowers in dense cone-like, cylindric spikes. 



1. B. lupulina 



2. Leaves elliptic to elliptic-ovate 2. B. prionitis
