Jambosa vulgaris, DC. 'Pomaroso,' on account of the shape and 
smell of the fruit.— Alph. De Candolle (1. c. 893) seems to doubt whether 
/. vulgaris is cultivated in America, as Maycock refers the Rose-apple 
of Barbadoes to /. macrophylla, DC. I cannot decide whether this be 
right or wrong, but the c Pomarosa' of Venezuela (and probably of most 
American countries) is certainly J. vulgaris, DC, as described in the 
Prod. iii. p. 286. The tree is very common near Caracas, but the fruit 
not much esteemed.

NOTE ON PENTHORUM CHINENSE, Pursh. 
By H. F. Hance, Ph.D., etc. 
In the month of September, 1866, Mr. Sampson and myself dis- 
covered this plant at J Ng-ng;i-hau, about eight miles above Canton, 
growing under the shade of Ghjptostrobus trees, in the muddy bed of 
the river, and often almost entirely submerged. This is, I believe, the 
first record of its being met with in the soutb of the Empire, for Sir 
George Staunton's specimens were probably collected in the north,* and 
in recent times it has only been found in North China, Manchuria, 
along the Ussuri, and in Japan. 
Notwithstanding that such very high authorities, and so little dis- 
posed to multiply species as Mr. Bentham and Dr. Hooker, in the 
1 Genera Plantarum, 5 and Dr. Regel (Tent. Fl. Ussur., 65),— the latter, 
however, giving no. other constant character than the narrow leaves, — 
hold this to be distinct from P. sedoides, I do not hesitate with Pro- 
fessors A. Gray (on the Bot. of Japan) and Miquel (Ann. Mus. Lugd. 
Bat. ii. 76) to look on it as merely a geographical .variety of that 
species. The seeds of my specimens, which really look like small 
Apings or filings, and are hence, notwithstanding Miquel's objection, 
tvell described by the term scobiformia, are yellowish, oblong, straight 
°r curved, acute at both ends or rounded at one, angular, so that a 
transverse section would usually show a trigonous figure with one con- 
vex and two plane faces, and muriculate on the surface. Hence, it is 
clear that these do not furnish the characters relied on for the discri- 
mination of the Asiatic plant. The South-Chinese examples, with 
■Prtafau or 1-5-petalous Sowers, agree perfectly with Kegel's plate 
* The specimens is Herb. Mus. Brit. are from the "Province of Kianang."— Ed.
