the lofty mountains of Ecuador (alt. 7-9000 feet), and from 

 Mr. M'Lean, from Vita, Peru, and from Hartweg, New Granada, 

 n. 1006. De Candolle, however, and Naudin consider it to be 

 identical with the Rhexia dicrananthera, Ruiz and Pavon, 1. c, 

 which is the authority for the Arthrostemma dicrananthera of 

 De Candolle. It may be so, but Ruiz and Pavon's figure re- 

 presents a more sturdy plant, with much smaller leaves, exactly 

 and broadly ovate, obtuse at the base (" ut plurimum pollicaria, 

 latitudine semipollicaria"), which leads me to doubt of the cor- 

 rectness of that reference. 



It is an excessively pretty plant, deserving a place in every 

 warm greenhouse. Our plants were reared from seed received 

 from Professor Jameson by Isaac Anderson, Esq., of Hay Lodge, 

 Trinity, Edinburgh, a most successful cultivator of plants, espe- 

 cially those which he raises from seeds sent him by Professor 

 Jameson, from the lofty Andes of South America. The species 

 flowered abundantly with us in October, 1864. 



Descr. A small skru6,which with us has attained a height of 

 a foot to eighteen inches, erect, much branched, especially up- 

 wards, everywhere clothed with purple-brown setaceous hairs, 

 appressed upon the foliage, generally spreading on the rest of 

 the plant. Leaves always opposite, shortly petiolate, one to two 

 and a half inches long, firm, rigid, bright-green above, pale be- 

 neath, elliptico-lanceolate, obtusely acuminate, acute at the base, 

 five-nerved, nerves impressed above, prominent beneath. The 

 upper half of the plant, or more, consists of a series of small 

 flowering panicles, collectively forming an oblong, multiflorous, 

 large panicle, mixed with a few leaves, which, upwards, be- 

 come small, narrow-lanceolate bracts. Tube of the hispid calyx 

 ovate; limb rather shorter than the tube, five-lobed; lobes four, 

 spreading, ovate, acuminate. Stamens eight, all inclined to one 

 side, alternately a little larger. Filaments subulate. Anther 

 suddenly deflexed, as long as filament, subulate, opening by a 

 solitary pore ; spur erect, subulate, nearly as long as the anther. 

 The lesser stamens seem to be sometimes abortive ; the spur the 

 same as in the perfect stamens, but smaller. Petals four, sub- 

 rotund, bright rose-colour. Ovary ovate, with the base only ad- 

 nate with the inner tube of the calyx, by means of four elevated 

 ridges. The rest free, setose on the summit, at the base of 

 the style. Style longer than the pistil, flexuose. Stigma a mere 

 point.
