A tall herb, native of the drier forests of the upper part 
of the Malay Peninsula, extending northward from Moul- 
mein in Tenasserim to Pegu, and eastward into Burma, 
flowering in the dry season. It belongs to a class of 
Acanthaceous plants that are very suitable for winter 
decoration, flowering freely under proper treatment, which 
consists very much in careful watering at the time when in 
their native country little or no rain falls. Several species 
are in cultivation under the names of Hranthemwm_and 
Justicia, as D. nervosus, Plate 1358, and D. strictus, Plate 
3068. : 
D. macrophyllus has been long cultivated at Kew, having 
been introduced, no doubt, from the Calcutta Botanical 
Garden; it has flowered freely in the Palm House and 
elsewhere during the winter months. 
Desor. Erect, two to three feet high, sparingly branched, 
more or less puberulous with appressed scattered very small 
hairs on both surfaces of the leaves, and with spreading 
short glandular hairs on the stem branches above bracts 
and inflorescence generally. Leaves petioled, lower five to 
May Ist, 1883.
