 Baron, 149 ! A near ally of the Mauritian G. psychotrioiiles, Baker. 

 We have two other undescribed species of this genus from Mada-

Tabern.emontana modesta, n. sp. — A shrub, glabrous in all its 

 parts, with slender terete branchlets. Leaves opposite, distinctly 

 petioled, oblong, entire, obtusely cuspidate, 1^2 in. long, mode-

 ascending main veins. Cymes few-flowered, axillary ; peduncles 

 twice as long as the petiole ; bracts minute, deltoid ; pedicels 

 \-^ in. long, cernuous in the flowering stage. Calyx about -^ lin. 

 long; tube campanulate; segments minute, deltoid. Corolla % in. 

 long ; tube cyhndrical, exceeding the oblique oblong segments. 

 Stamens inserted above the middle of the corolla-tube. — Forests 

 of West Betsileo, Baron, 150 ! Nearly allied to T. yyiauritiana, Poir., 

 and T. cofecpfolia, Bojer. 



Pachypodium rosulatum, n. sp. — Stem short, stout, succulent. 

 Leaves in a dense rosette at the tip of the branch, oblong, sessile, 

 obtuse, i-f in. long, subcoriaceous, thinly tomentose above, densely 

 tomentose beneath, with the crowded parallel veins visible through 

 the white tomentum, densely woolly at the base, and the branch 

 beneath the rosette of leaves armed with crowded spreading brown 

 pungent prickles ^^ in. long. Flowers 6-8 in a dense cyme at 

 the summit of a naked shortly tomentose peduncle nearly a foot 

 long; bracts small, lanceolate, pilose; pedicels finally ^ in. long. 

 Calyx ^-^ in. long, densely pilose, with a short campanulate tube, 

 and five lanceolate acuminate segments. Corolla yellowish, 1^ in. 

 long, pilose on the outside, especially towards the base ; tube 

 cylindrical at the base, the upper part dilated, above ^ in. diam., 

 campanulate, slightly oblique ; segments deltoid, half as long as 

 the tube. Anthers lanceolate, connivent, f in. long, inserted at 

 the throat of the contracted lower half of the corolla-tube. Ovary 

 densely pilose, surrounded by the brown unequal connate glands 

 of the disk ; style slender, densely pilose, bringing the stigma on a 

 level with the middle of the anthers. Ibara-country and Betsileo- 

 land, Baro7i, 256 ! Allied to Adenium namaqiianum , Harv. Thes.
