Robinson and Greenman—Mexican Plants. 161 
3—4-lobed rim: corolla rotate, pentagonal, nearly entire: stamens 
erect, unequal, one longer: fruit globose, bright red, nearly half 
inch broad.—Collected by C. G. Pringle, in mountain cafions near 
Guadalajara, 18 November, 1892 (No. 5343), 
CHamM#saRAcHA Potosina. JDensely glandular-pubescent, 
freely branched: stems and branches subterete, finely striate: 
leaves geminate, ovate-lanceolate, acute, contracted below to a 
shortly cuneate base, thin in texture, the larger ones 18 to 22 
lines long, half as broad: pedicels solitary or less frequently in 
pairs, 4 lines long in anthesis : calyx 5-toothed almost to the mid- 
dle, nearly enveloping and closely appressed to the fruit, but 
finally ruptured and more or less reflexed, teeth ovate, acute, cili- 
ated : corolla rotate, 5-toothed, nearly to the middle, 4 lines broad, 
pale yellow, pubescent in the throat; segments ovate, acute, 
pubescent upon the outer surface near the tip and ciliate: fila- 
ments nearly twice as long as the oblong anthers: fruit globose, 
red, the size of a pea.—Collected by C. G. Pringle, in Tamasopo 
Cafon, San Luis Potosi, 25 November, 1890 (No. 3654). Leaves 
quite entire, thinner than in the other Mexican species, and corollas 
smaller and more deeply divided. 
SARACHA GRANDIFLORA. Densely cinereous-pubescent : stems 
angulate, tomentose: leaves single or geminate, ovate, undulate 
or somewhat sinuate-dentate, obtusish, appressed-villous upon 
both surfaces, pale beneath, 25 inches long, 2 inches broad, 
abruptly contracted at the base but decurrent into tomentose 
petioles 6 to 7 lines in length: peduncles axillary, 3 to 7 lines 
long, about 3-flowered; pedicels 7 to 9 lines in length: calyx 
appressed-villous, about 10 lines broad in anthesis, 14 inches in 
fruit, with 5 shallow triangular blunt lobes: corolla pentagonal, 
scarcely lobed, pubescent on the outer surface, conspicuously cili- 
ated, 14 lines in diameter: stamens rather close in the throat; 
filaments nearly or quite glabrous but a line or two long: fruit 
globular, 5 lines in diameter.—Collected by C. G. Pringle, on 
hills near Patzcuaro, Michoacan, 22 July, 1892 (No. 5273). 
JUSTICIA LINEARIS. ‘Tomentulose, fruticose: leaves linear, 
crowded near the ends of the ascending cinereous branches, erect, 
an inch in length, a line in breadth, 1-nerved, sessile; margins 
strongly revolute: flowers sessile, axillary: calyx deeply 5-parted; 
segments sub-equal, linear, attenuate, 4 lines long: corolla pubes- 
cent upon the outer surface especially upon the veins, about 9 
lines in length with an ampliate throat, the upper lip very shortly 
bifid; the lower more deeply 3-parted, the segments rounded, the 
middle one the largest : stamens of the genus: styles slightly 
pubescent below, minutely and unequally bidentate at the apex; 
valves of the capsule half inch long.—Collected by C. G. Pringle, 
upon dry hills, Las Tablas, San Luis Potosi, 5 August, 1891 (No. 
5038). This species showing all the floral characters of Justicia, 
is very distinct in habit from any species known to us. It was 
collected in a season of especial drought and only a very limited 
quantity of material secured.
