present. ‘The name however is unhappily chosen, for our living 
plants bear frequently three flowers from a peduncle. Dr. 
Lindley justly observes that Siebold and Zuccarini’s 4. serrata 
of Japan is very near our present plant; and a small authentic 
specimen I have in my possession would tend to confirm that 
opinion. The pubescence is a variable character, and so as- 
suredly is the degree of serrature on the leaves, so likewise the 
size of the flowers and the number of sepals. In our specimens 
the latter vary from two to four: in the 4. serrata they are de- 
scribed as five. | 
Drscr. A spreading, somewhat decumbent, small shrub, with 
slender dranches, and usually opposite, but sometimes ternate, 
broad, lanceolate, shortly petiolate, acuminated, subcoriaceous, 
dark green, perennial eaves, pale beneath. Peduneles axillary, 
short, scarcely longer than the petioles, bearing one to three 
flowers. Calyw-tube oblong-cylindrical, furrowed, slightly hairy, 
subtended by an involucre of three small bracteoles: the limb 
- generally of two, but varying to three and four, oblong-spathu- 
_ fate, nerved, red-brown, spreading sepals, longer than the tube, 
but less than half the length of the corolla. Corolla white, 
tinged with blush; the tude infundibuliform, narrow, dilated at 
the base into an obtuse spur; the limb obscurely two-lipped ; 
upper lip two, lower one three-lobed, the lobes obtuse, spread- 
mg; the throat wide, hairy on the lower surface, and streaked 
with yellow. Stamens four, included, didynamous ; style rather 
longer than the stamens, Slender ; stigma capitate.
