"Weir's plant is from the same province as that of Riedel's. It is a climbing species, 

 with stoutish, flexuose, pale, subfistulous branches, covered with a short yellow tomentum, 

 with dilated axils 5 in. apart, furnished along the transverse ridge with several pectinoid 

 stipules ; leaves ovate, at the base suddenly and acutely constricted upon the petiole, 

 with an abrupt acute acumen, submembranaceous, pallid green above, with short dense 

 yellow pubescence on the flattened midrib and on 5-6 pairs of arching prominulent 

 netves and transversely reticulated veins, beneath of a yellowish hue, shortly tomen- 

 tellous, especially on the little prominulent nerves and veins, 4f in. long, 2^-3 in. broad, 

 on stout floccose petioles 9 lines long ; corymb solitary and lateral at the nodes, with a 

 peduncle rising out of an involucel of scales, 1 in. long, somewhat 2-branched, each 

 branch laxly flowered, puberulous ; flowers mostly geminate upon slender pedicels 

 6 lines long, with corresponding opposite linear-oblong bracts of the same length; sepals 

 oblong, acuminate, pilose on both sides, 5-7 lines long, 2 lines broad, each with an inner 

 broadly ovate truncate scale denticulate at the apex ; tube of corolla broadish, cylin- 

 drical, reddish, glabrous, 6 lines long, thickish in the mouth, without appendages ; 

 segments oblong-ovate, inequilateral, 4 lines long, 2^ lines broad, glabrous^; stamens 

 inserted upon 5 pilose lines in the middle of the tube ; anthers acuminate, 3^ lines long, 

 with 2 basal divaricate prongs 1 line long.

I found this plant in flower in Jan. 1838. It approaches T. solanifolia in habit, dif- 

 fering in its smaller leaves, and flowers aggregated in a more capitate head ; its branches 

 are only | line thick, its axils 3|-4^ in. apart, with many stipules \ line long ; leaves 

 1^-3 in. long, |— | in. broad, on petioles 2-2^ lines long ; corymb \^ in. long ; peduncle 

 bare for fin., its branches many-flowered from the base on pedicels 4-5 lines long; 

 sepals 2^-3 lines long, 1 line broad; tube of corolla narrower in the middle, 5 lines long; 

 segments 3 lines long, 2 lines broad ; anthers 2^ lines long.
