fused over the branches, and never crowded near the root, as so many 

 of them are in O. taraxacifolia and O. triloba; and, lastly, by the absence 

 of the lobed crown to the capsule which both of these have. 



Physianthus albens. 



P. aliens ; herbacea, volubilis, foliis oppositis integerrimis acutis basi 

 cordato-truncatis subtus albo-pruinosi, floribus subdichotomo-cymosis.

 Physianthus albens, Mart. Nov. Genera et Sp. Plant. Brasil. i. 54. t 32. 

 Deschiption.— /?oo/ woody, branched, and fibrous. Stem woody (at least 

 when cultivated in the stove), round, branched, twining; bark green, 

 cracked, and on the recent shoots, which are very long and slender, 

 pretty densely covered with short adpressed pubescence. Branches op- 

 posite and axillary, Spreading. Leaves (3 inches long, 1| broad) petioled, 

 opposite, oblong, truncated below, undulate, entire, acute, deep green 

 and pruinose above, paler below, and there especially clothed with mi- 

 nute pubescence. Petiole about one-third of the length of the leaf^ of 

 the same colour with the shoots, channelled above, spreading. Pe- 

 duncles lateral, more rarely ajtillary, subdichotomously cymose, 4-8- 

 flowered, about as long as the petiole, and like it ; pedicels (about 7 lines 

 long) spreading, straight. Calt/a; 5-parted, green, very minutely tomen- 

 tous, obscurely veined ; segments ovate, acute, spreading below, erect in 

 their upper half, reflected at the sides. Corolla faintly perfumed, some- 

 what fleshy, white, when in bud pale rose-coloured, hypocraterif brm, gla- 

 brous ; tube (half an inch long) one and a half times as long as the calyx, 

 at its base yentricose with five gibbosities and slightly hairy on the in- 

 side, above 5-gonous, sides depressed, and having a ridge in the centre 

 of the depression ; limb (IJ inch across) spreading, 5-parted, segments 

 ovate, acute, reflected at the apices and at the sides. Crown attached to 

 the inside of the base of the tube, 5-parted, lobes connivent, blunt, con- 

 vex on the outside, alternate with the gibbosities of the tube, glabrous. 

 Stamens opposite to the lobes of the crown, and twice as long as these, 

 adpressed to the pistil ; filaments coarse and fleshy, monadelphous, con- 

 cave on the inside, flat on the out, sagittate above, terminated by a little 

 ovate subacute point, below the sides of which, and on the inside of the 

 filament, are the cells of the anther ; pollen-masses yellow, elliptico-ovate, 

 flattened, reticulated. Stigma larg-e, conical, angular, terminated above 

 by two appendages longer than itself, which diverge below, meet above 

 near the apices, and again diverge; glands alternate with the stamens, in- 

 dented into the angles of the stigma, deep lilac, cartilaginous, slit verti- 

 cally along their outer surface, terminated above by a cordate brown pro- 

 cess, emarginate at the apex, and below by two processes, which are brown, 

 linear, flat, swollen at both their extremities, each becoming attached ob- 

 liquely to the narrower extremity of a pollen-mass in the stamen next 

 to it. Stf/les 2, short, connivent above. Germens 2, turgid, ovate, acute. 

 Ovules very numerous, small, imbricated, filamentous, attached to the 

 receptacle placed on the inside of the germen. 

 Seeds of this fine plant were received by Mr Neill Irom Mr Tweedie, 

 Buenos Ay res, in 1 830, and, climbing along the roof of the stove in his 

 garden, flowered freely in August last. I possess from Mr Tweedie an 

 excellent specimen, in no respect different from the cultivated plant. 



Stylidium junceum. 



S. junceum ; foliis radicalibus linearibus : scapi strict! glabri minutis dis- 

 tantibus bracteisque medio adnatis, calycis laciniis subulatis : basi sim- 

 plici, fauce glandulis stipitatis coronata, lobello inappendiculato. — Br. 

 Stylidium junceum. Brown's Prodr. Fl. Nov. Holland. 1. 5fi9. 

 Description — Root fibrous, perennial, pushing several stems (scapes) from 

 the crown. Root-leaves crowded, linear, glabrous, somewhat fleshy, cal- 

 lous at the tip : stem-leaves (bracte«) minute, green and fleshy, attached 

 by the middle, acuminated at both ends, or rarely emarginate below, ad- 

 pressed. Scapes (nearly 2 feet high) erect, slender, gteen, round", gla-
