440 TETRANDRIA MONOGYNIA+ Ludwigia, 
petioled, from six to twelve inches long, with pointed, prickly peti- 
als. Leaflets almost sessile, lanceolate-oblong, rounded and nearly 
equal at the base, apex tapering into a narrow acumen, about three 
inches long, with undulated margins, eutire or notched with remote | 
glandular indentures, especially while young, shining above, with 
numerous sub-marginal, glandular, transparent dots; pale beneath, 
with a more or less prickly rib.—Racemes from one to three, fascicled 
in the exterior axils, a couple of inches long, erect, cylindric, on short 
villous round peduncles, covered with numerous white, fragrant, short- 
pedicelled flowers. . Calyx flat, with very small ovate acute seg- 
ments. Petals lanceolate, slightly concave, four times longer thaa 
the calyx, ending in a short point. Stamina twice the length of the © 
petals, spreading.—Pistilla? four, ovate, small, ending in a short re- 
curved style; stigma acute, marked above with a short tooth, 
It appears to be the same as Loureiro's l'agara piperita, Flor. 
Cochiuch. ed. Willd. i. 101, differing from Linneus's plant, as has 
been justly remarked in CM and Schult. Syst, Veg. iii. 296. It 
has also some resemblance to Tetradium, Lour. J. cit. 115. which 
Sir J. E. Smith considers as related to Fagara.—I have not been able 
1o discover any ovula in the four bodies in the centre of the flower, 
which therefore may be considered as nectaries or abortive pistils, a 
supposition which is much strensthened by the circumstance that 
none of the shrubs in the garden have produced any fruit. This 
dioicous species ought therefore to be referred to Zanthoxylon as 
suggested by Dr. Roxburgh.—All its younger parts and leaves have 
a slightly pungent aromatic taste and smell.—N. W. ^
