Ikscription of several New or Rare Plants 'which have lately 

 Jloxoered in the neighhoiirhood of Edinburgh^ and chuifly 

 in the Royal Botanic Garden. By Dr Gjiaham, Profes- 

 sor of Botany in the University of Edinburgh. 



March 10. 1833. 

 Acacia decipiens, var. praemorsa. 



A.prcemorsa; stipulis spinescentibus, 'deciduis ; phyllodeis triangulari- 

 bus, passimq^iie trapezoideis, nervo lateri inferiori approximato in spi- 

 nam producto, margine superiore denie acuto unico glandulifero (va- 

 rietate, saepius praemorso dentibus duobus vel tribus glanduliferis) ca- 

 pitulis subsolitariis multifloris. 

 Description. — Shrub erect, twigs arched, angled, glabrous ; bark on the 

 stem brown, on the twigs green. Phyllodium with one nerve, which 

 passes near its lower sied, triangular, the upper angle, excepting at the 

 apices of the branches, truncated, and terminating in two or three short 

 points tipped with glands, the lower angle extended into a prickle, the 

 continuation of the nerve. Stipula spinescent, spreading, subdeciduous. 

 Peduncles glabrous, pellucid, spreading, longer than the phyllodia. 

 Flowers yellow, capitate, numerous in each capitulum. Cali/x 4-toothed, 

 teeth blunt and ciliated. Corolla 4-petaled, petals lanceolate, reflexed. 

 Stamens numerous, longer than the corolla. Pistil longer than the sta- 

 mens; germen ovate, tomentous. 

 We received in 1831, at the Botanic Garden, Edinburgh, from Mr Knight 

 of the King's Road Nursery, the plant here described, under the name 

 of Acacia pramorsa. I presume it was imported by Mr Baxter. I can- 

 not, however, consider it other than a variety of A. decipiens, distin- 

 guished chiefly by its paler flowers, by the petals being more reflected, 

 allowing the stamens to spread more, and thus producing a capitulum 

 less distinctly lobular, and further, by the upper angle of the leaf be- 

 ing more frequently irregularly truncated than in A. decipiens. 

 It flowered very freely with us in the greenhouse, with the usual treatment 

 of New Holland acacias. 



Baccharis alata, mas. 



B. alata ; fruticosa, caule interrupte tri-alato ; foliis sessilibus, cordatis, 

 obtusis, integerrimis, lateribus reflexis ; floribus fasciculato-spicatis, 

 terminalibus. 

 Description — Stem (in our specimen above 5 feet high) shrubby, inter- 

 ruptedly 3-winged, branched, branches erect, and, as well as the wings, 

 green, rigid, scabrous. Leaves erect, often oblique, placed at the inter- 

 ruptions of the wings, sessile, cordate, blunt, reflected at their sides, sub- 

 scabrous, obscurely veined. Flowers pale yellow, sessile, fasciculato-spi- 

 cate at the extremities of the branches, fasciculi 3-4-flowered. Antho- 

 dium orbiculato-ovate, scabrous. Florets all male, funnel-shaped, limb 

 spreading, segments acute, at length revolute. Anthers exserted. Pap- 

 pus simple, as long as the florets. Receptacle slightly conical, somewhat 

 hispid. 

 We received this plant at the Botanic Garden in 1829, under the name 

 here adopted, from the Berlin Garden, but without any statement of its 

 native country. It flowered freely in the greenhouse in December 1832, 

 but is curious rather than ornameutal.
