GREENMAN, ——~ CENTRAL AMERICAN SPERMATOPHYTES, 33 
long, deeply 5-parted, puberulent; the posterior segment much smaller 
than the other segments: corolla, 2-lipped, purple; tube slender, cylin- 
drical, 22 mm. long, externally pubescent; upper or posterior lip sub- 
erect, entire, acute; lower or anterior lip deeply 3-lobed, spreading : 
capsule 12 mm. long, pubescent: seeds verrucose.— Mexico. State of 
Tamaulipas: Soto la Marina, 2 March, 1902, £. W. Nelson, no, 6650 
(hb. Gr., and hb. U. S. Nat. Mus.). State of Nuevo Leon: near 
Monterey, 19 March, 1900, William M. Canby, no. 187 (hb. Gr.). 
‘State of Hidalgo: Zimapan, 7h. Coulter, no. 1213 (hb. Gr.). This 
number of the Coulter collection was referred by Hemsley, Biol. 
Cent.-Am. Bot. ii. 516, to Siphonoglossa pilosella, Torr., from which 
species it is certainly distinct. From the shape of the corolla the 
species here described might very well pass as a Siphonoglossa, but the 
character of the inflorescence and the absence of a spur or any appen- 
dage on the lower anther-cell place it rather with Justicia ( Dianthera). 
Tn general appearance Justicia (Dianthera) Canbyi is not unlike certain 
Rhinacanthi of the Old World. 
Ranpia opcorpata, Watson, Proc. Am. Acad. xxiv. 53. The only 
recorded station for this species is the original locality, namely, on high 
mesas near Guaymas, State of Sonora, Mexico. Its occurrence at Man- 
zanillo, State of Colima, where excellent fruiting specimens were secured 
by Dr, Edward Palmer, 2 to 18 March, 1891, no. 801 (hb. Gr., and 
hb. U. S. Nat. Mus.) indicates that the species has a rather extended 
distribution along the west coast of Mexico.

State of San Luis Potosi: Alvarez, 28 September to 3 October, 1902, 
Dr. Edward Palmer, no. 147 (hb. Gr., and hb. U. S. Nat. Mus.). 
Stevia vernicosa, n.sp. Shrub, 1 m. or less high: stem branched ; 
branchlets terete, often verrucose, glabrous or somewhat pubescent 
towards the inflorescence, reddish: leaves opposite, lance-elliptic to 
oblanceolate, 1.5 to 4.5 em. long, 4 to 8 mm. broad, obtuse, rather closely 
serrulate or crenate-sertulate, narrowed below to.a subpetiolate base, 
glabrous, glandular-punctate and glutinous: heads about 12 mm. high, 
5-flowered, disposed in dense cymules terminating the stem and branches: 
inyolucre 6 to 8 mm. high; bracts of the involucre 5, lanceolate, acute 
or obtuse, glutinous: pappus of 1 to 5 setae nearly or quite equalling 
the corolla-tube, and of 5 minute scales: corollas white: mature achenes 
4to 4.5 mm. long, puberulent.— Mexico. State of Morelos: on dry 
ledges, Sierra de Tepoxtlan, altitude 2310 m., 15 March, 1899, C. G.
