wise of that division, I am unable to offer any opinion, 

 never having seen it, but I am not prepared to go along 

 with him in viewing the two plants here represented as 

 the same species, though nearly allied. When naming 

 the drawings, I adopted Blame's views, and still, perha|)s 

 erroneously, retain his name. He may be in error in 

 considering the Java plant identical with the American 

 one, but not in viewing his^, alba as distinct from his 

 A. tomenlosay if I have not erred in viewing these as 

 his plants. 



1841. AvicENNiA TOMENTosA (Lin, Blume, A* affici- 

 naViS^ Lin., Schauer), leaves obovato-cuneate, obtuse, 

 glauco-tomentose beneath. Bl. 



Malabar coast, and generally to be met with in salt 

 marshes on both coasts of the Indian Peninsula. 



A small tree or considerable shrub, with obovate, 

 obtuse, coriaceous leaves, light green above, whitish 

 or greyish beneath ; petiols densely villous above : 

 peduncles axillary and terminal, trichotomously pani- 

 cled; branches short, stout, terminating in a single 

 capitulum, or elongated and bearing several sessile, 

 lateral ones ; bracts concave, coriaceous, 3 to each 

 flower, and, like the calyx lobes, ciliate, calyx 5-parted, 

 lobes ovate, obtuse, glabrous. Corolla scarcely exceed- 

 ing the calyx, 4-cleft, lobes ovate, acute, pubescent on 

 the back, yellow: stamens 4, about equal, scarcely ex- 

 serted; anthers globose, deeply furrowed between the 

 cells. Ovary ovate, pubescent, imperfectly 4-celled, 

 with 2 ovules in each, pendulous from the free apex of 

 an erect, central placenta : style short, cleft at the apex: 

 fruit oblique, ovate, compressed, apiculate, roundish at 

 the base, supported by the persistent calyx and bracts. 



Schauer has revived for the this species Linnaeus' 

 specific name "officinalis," and I think correctly, as it 



differs in some points from the American plant to which 



he restricts Linnaeus' *Homentosa." Linnaeus however 

 did not think them distinct, as he afterwards reduced 

 his A. officinalis. In the American plant, the flowers 

 are white, in the Asiatic one, yellow, a difference which, 

 in so difficult a genus, ought not to be overlooked in the 

 determination of its species,

 ceolate, acute, or slightly obtuse, glabrous, whitish 

 beneath. Bl. 



Tellicherry, Malabar Coast* 



In addition to these brief characters, the habit of the 

 two plants is very distinct and is well preserved in the 

 figures. Admitting therefore that the Asiatic plants are 

 distinct from the American, they must equally be view- 

 ed as distinct from each other and may perhaps be thu*; 

 defined : 



A. officinalis (Lin.), leaves obovate or obovato-cuneale, 

 coriaceous, glabrous above, glauco-pubescent beneath, 

 peduncles axillary, solitary or sub-panicled, terminal: 

 with several sessile capitula, or a single terminal one, 

 bracts and lobes of the calyx coriaceous, concave, ciliate : 



sub-acute: corolla 4-cleft: stamens as long as the lobes, 

 exserted: style about the length of the ovary, slightly 

 cleft at the apex, segments acute, approximated. 



A. alha (Blume), leaves oblong, elliptico-lanceolate, 

 acute at both ends, glabrous above, whitish pulverulent 

 beneath: peduncles terminal, from the axils of the last 

 pair of leaves of tlie branches, long, slender; flowers 

 capitate: capitula compact, many-flowered: bracts and 

 calyx villous on the back, densely ciliate: corolla 

 scarcely exceeding the calyx, 4-cleft; lobes acutish: 

 stamens about half the length of the lobes, sub-incluse : 

 ovary densely hairy on the apex; style short, 2-cleft; 

 lobes dilated, lanceolate, spreading.
