tubiflora, Müll. 1. c. pp. 423, 454. Circa Mexico : non vidi. 
A scandent species with very slender branches; leaves lanceolate, cordate, acuminate, 
glabrous above, cinereo-tomentous beneath, on short petioles; racemes bearing many 
large reflected flowers; calyx of 5 glabrous sepals, one quarter the length of the corolla ; 
corolla subtubular, with short, very obtuse rotate segments; follicles 2, long, slender, 
appressed. 
Müller states that this species is near Z. brachyloba and E convolvulacea.

(Karwinsky 473 & 1347) : non vidi. 
A peculiar species, evidently belonging to this genus on account of the glands on the 
midribs of the leaves and the characters of its flowers. It is a prostrate plant, having the ` 
habit of Echites torosa, Jacq., with ascending, slender, subscandent, erect branches 1 foot 
long, which are reddish-fuscous and obsoletely griseo-puberulous ; leaves oblong-ovate or 
lanceolate-spathulate, narrowed and obtuse at the base, shortly acute at the summit, 
membranaceous, fuscous, glabrous, shining above, with 4-6 pairs of nerves and others 
intermediate, reticulately veined, the midrib charged with 2-3 glands, 1-12 in. long, 
23-7 lines broad, on petioles 1 line long; racemes axillary, as long as or longer than 
the leaves, glabrous, on a peduncle 5-6 lines long, bearing many flowers on rigid | 
pedicels 3 lines long, supported by linear-lanceolate bracteoles 1} line long ; sepals ovate- 
lanceolate, acuminate, orange-coloured, with dark spots and hyaline margins, 22 lines 
long, with 4-7 inner subulate scales; corolla in the whole 9} lines long; tube cylindrical 
for half its length; segments rhomboidally obovate, acute at one angle; anthers short; 
disk of 5 obtuse lobes, as long as the 2 obtusely ovoid ovaries. 
39. Ecuttes AxpRrEUXII, nob.: Amblyanthera Andrieuzii, Müll. l. c. p. 422. Circa Oaxaca (Andrieux 
249) : non vidi. 
A subscandent species, near S. Karwinskii, with terete, glabrous, reddish, subverrucose 
branchlets 1 line thick; branches at the base (and probably the axils) surrounded by a ring 
of scaly glands, densely foliaceous above; leaves narrowly obovate, or obovate-lanceolate, 
acute at both ends, rigidly membranaceous, fuscous, hirto-puberulous above, with about 6 
pairs of nearly obsolete nerves, yellowish beneath and softly pubescent, 93-15 lines long, 
31-1 lines broad, on petioles 14-24 lines long; racemes axillary, a little longer than the 
leaves, subglabrous, a little deflexed, simple, bearing few pedicellate flowers, the 2 lower 
ones opposite, the rest alternate, on rigid pedicels 1-13 line long, supported by lanceolate 
puberulous bracteoles of the same length ; sepals ovate-lanceolate, puberulous outside, with 
membranaceous margins, 14 line long, having as many subulate inner scales; corolla 
altogether 52-7 lines long; tube rather broadly cylindrical, somewhat thicker at the 
base, swelling campanularly above to a breadth of 2 lines ; segments rhomboidally obovate, 
half as long as the tube; disk of 5 free obtusely oblong lobes, as long as the 2 ovoid 
ovaries.
