616 oxi LABIATE. (J. D. Hooker.) [ Plectranthus. 
8. PLECTRANTHUS, L Herit. 
Herbs or undershrabs. Flowers usually small, in lax (rarely close) 
panicled or racemed 6-8-fld. cymes (whorls). Calyx 5-toothed, 2-lipped, 
enlarged in fruit. Corolla-tube exserted, long or short, straight or decurved, 
limb equal or gibbous or spurred, 2-lipped; upper lip usually short, broad, 
3-4-fid recurved ; lower much longer, entire, boat-shaped, narrow at the base 
or stipitate. Stamens 4, declinate; filaments simple, free; anther-cells 
usually confluent. Dise usually produced in front, and there equalling or 
exceeding the ovary. Style subequally 2-fid. Nutlets orbicular, ovoid or 
oklong, smooth, granulate or punctate.—Species about 80, Tropical and Sub- 
tropical Asiatic, African, Australian and Polynesian. 
The species of the sections Isopon and CoLEOIDES are numerous and very 
difficult of discrimination, and the latter should perhaps be referred to Coleus, or better 
still refer all the Plectranthi to sections of Coleus, of which genus P. coleoides and 
urticifolius have all the habit, 
Sect. l. Isodon. Fruiting calyx decurved, subequally 5-toothed, or 
2-lipped, upper lip 3-toothed, lower 2-toothed. Wutlets oblong or rounded, 
obtuse. l 
* Fruiting calyx broad, open, deeply 2-lipped, upper lip very broad with 
3 distant spinous teeth, lower of 2 long subulate teeth. Corolla 1 in. long, 
tube straight, base equal. 
15751. P. macranthus, Hook. f.; sparsely hairy, leaves petioled ovate- 
lanceolate coarsely serrate, inflorescence racemose, flowers opposite.

Stem 6-12 in., simple or branched, weak. Leaves 3-5 in., membranous. Racemes 
6-12 in.; bracts ovate-lanceolate. persistent; pedicels } in. Corolla-tube straight, 
l in. long, j in. diam. ; lips short, subequal, rounded. Fruiting calyx } in. long. 
Nutlets globose, 3, in. diam.—Very near the Japanese P. longitubus, Miq., and possibly 
a variety of it, but the eyme branches are much shorter and 1-fld, ; the inflores- 
cence being a simple raceme with opposite flowers. — Probably both should be referred 
to Orthosiphon. 
** Fruiting calyx longer than broad, distinctly 9-lipped for 3 way down, 
upper lip subequally 3-toothed, lower 2-toothed. Corolla 3-4 in. long, tube 
wet base equal. (It is not easy to distinguish this section from the 
next. 
2. P. scrophularoides, Wall. P7. As. Rar. ii. 16,and Cat. 2738; tall, 
slender, nearly glabrous, leaves long-petioled ovate crenate, base cordate or 
cuneate, corolla-tube broad about twice as long as the lower lip, fruiting 
calyx with obtuse teeth, nutlets subglobose smooth. Benth. Lab. 40, and in 
DC. Prodr. xi. 55; Hook. Ic. Pl.t. 464 in part. 
TEMPERATE HIMALAYA, ult. 8-1000 ft., from Kumaon to Sikkim; Wallich, &c. 
Stem 2-4 ft. or more. Leaves 3-7 in., often as broad, sparsely minutely hairy ; 
petiole 1-4 in. Cymes in broad open slender panicles. Corolla À in., pale rose, tube 
nearly straight, upper lip very short, lower short, narrow, acute, hardly cymbiform. 
Stamens far exserted. Fruiting calyx } in.—A much larger plant than P. Gerardi- 
anus, which it closely resembles, ‘The figure in Icones Plantarum (copied from a 
drawing by Heyland of Paris) is, I suspect, made up of the magnified calyx and corolla 
of this, but of the leaves, panicle and nutlets of P. Gerardianus.
