latum, a rather common Indian hill plant, which I gathered 
at Chittagong, and which extends thence to Java, and is 
also found in Ceylon and the Madras Peninsula. 
The history of Z. crenulatum* is obscure ; it first appearsin 
the Botanical Register (Tab.'879) in 1825, as a ms. name of 
Wallich’s, applied to a plant from Silhet, which he sent to 
the Horticultural Garden in 1824, the very year in which he 
received Ff. palatiferum in the Calcutta Garden; but the 
Register figure is totally unlike the plant subsequently 
described by Nees as &. crenulatum (Wall. Pl. As. Rar., i. 
107), in having a small regular corolla with acute lobes, and 
is probably an Asystasia in a starved state. 'T. Anderson, in 
his enumeration of the East Indian Acanthacee (Journ. 
Linn. Soc., v. ix. p. 524), throws no light on the subject. 
Under these circumstances it appears to me best to retain 
the name palatiferum, as being that which Wallich applied 
to this plant, which he figures and describes well. It is 
further to be observed that Nees errs in putting £ ciana- 
barinum and this plant (his erenulatum) in the section of the 
genus with the corolla limb equal, it being strongly bilabiate 
in both; in so doing he has followed the Register plate, and 
not the specimens he has so named. 
The subject of our plate was sent to Kew from the Cal- 
cutta Botanic Garden, and flowered in April of last year ; it 
belongs to the var. glandulosum, in which the glandular 
pubescence of the inflorescence extends to the upper branches, 
and which inhabits the Malayan Peninsula. 
Descr. A small erect shrub; branches terete, glabrous or 
slightly glandular-pubescent. Leaves petioled, four to six 
inches long, blotched in our plant with white, quite entire or 
obscurely crenulate. pistes terminal, glandular-pubescent, 
simple or branched at the base, recurved, four to seven-inches 
long, many-flowered. F/owers subsecund, fascicled at regular 
intervals ; bracts subulate, one-sixth to one-quarter of an inch 
long. Calyx-segments linear-subulate, acuminate, one-third 
inch long or more. Corolla-tube very slender, one inch long, 
pale ; limb three-quarters to one and a quarter inches broad, 
flat, 2-lipped, lilac or scarlet, with a yellow spot on the lower 
lip; upper lip of two erect linear-oblong obtuse lobes ; lower — 
- with one orbicular mid-lobe, and two broadly oblong lateral 
ones, all rounded at the tip. Anthers blue.—J. D. H. .
