tubiflora, Miill. I. c. pp. 423j 454. Circa Mexico : non vidi. 



A scandent species with very slender brandies ; 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 ; foUicles 2, long, slender, 

 appressed. 



Miiller states that this species is near E. hrachyloha and E. convolvulacea.

(Karwinsky 473 & 1847) : 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 veiaed, the midrib charged with 2-3 glands, 1-lj in. long, 

 2|— 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-coloiired, with dark spots and hyaline margins, 2f 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. Echites Andrieuxii, nob. : Amblyanthera Andrieuxii, Miill. I. c. p. 422. Circa Oaxaca (Andrienx 

 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, 9^15 lines long, 

 3^-7 lines broad, on petioles 1^-2 J 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 1-1^ line long, supported by lanceolate 

 puberulous bracteoles of the same length ; sepals ovate-lanceolate, puberulous outside, with 

 membranaceous margins, If line long, having as many subulate inner scales ; corolla 

 altogether 5|-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.
