ARGYREIA (from aryyreios, silvery ; in reference to 

 the silvery undersides of the leaves). Silver-weed. OBD. 

 Conrolruiocea. An elegant genus of greenhouse and 

 stove climbers. Sepals five ; corolla campannlate. Shrubs 

 for the most part silvery, but sometimes silky and tomentose. 

 The greater number of the species are robust, extensive 

 twiners or climbers, usually requiring plenty of room to 

 run, before they will flower. A. cuneata, and one or two 

 others, are of dwarf habit, and produce their splendid 

 blossoms in abundance. All the species grow well in 

 light rich soil, or a mixture of peat, loam, and sand. 

 Cuttings root readily if planted in sand, with a hand glass 

 placed over them, in a little bottom heat. 

 A. capitate (headed). JL, corolla lin. to 2in. long, rose coloured 



or purple, hairy outside ; peduncles exceeding the petioles. July. 



J. cordate-ovate, acuminated, 2in. to Sin. long, and lin. to 3in. 



broad, hairy on both surfaces ; hairs glandular at the base. 



Plant clothed with strigose hairs. Silhet, 1825. 

 A. cuneata (wedge-leaved).* JL, corolla large, of a beautiful deep 



bright purple ; peduncles downy, shorter than the leaves, three to 



six-flowered. Julv. l. obovate-cuneate, emarginate, glabrous

AR6YR.OXYFHITJM (from argyrot, silver, and 

 Xyphion, a Corn-flag; in allusion to the leaves). OBD. 

 Composite. An ornamental greenhouse perennial herb. 

 Involucre campannlate; receptacle conical; heads pedun- 

 culate, racemose, or in thyrsoid panicles. Leaves alternate ; 

 lower ones close, elongated, thick, on both sides silver-lined. 

 Stems simple or slightly branched. It thrives well in rich 

 sandy loam and leaf mould. Propagated by seed-heads. 

 C. sandwlcense (Sandwich Islands), rt. -heads purplish. L linear 



lanceolate, imbricate, clothed, like the stems, with silvery hairs.

ARIS2EMA (from Ann, Arum, and sana, a standard; 

 in reference to the close alliance to Arum). OKD. Aroidea 

 (A raceas) . Small, tuberous-rooted, greenhouse (except where 

 stated otherwise) herbs. Spathe rolled round the spadix 

 at the base; spadix bearing unisexual flowers below, and 

 rudimentary flowers in the upper part. Leaves peltate, 

 pedate, palmate, or simple. For culture, &c., see Arum. 



A. ooncinna (neat).* JL, spathe convolute, tubular at the base ; 

 upper portion bent over at the month, and gradually narrowed 

 into a tail-like appendage about Sin. long ; spathe of the female 

 plant longitudinally barred with white and green, the latter 

 colour being replaced with blue-purple in the male. June. L

 lanceolate, entireTlight green leaflets, which radiate from the top 

 of the petiole, the latter being 1ft to 2ft high. Sikkim, 187L 



A. curvatnm (curved).* JL crowning a scape which overtops the 

 foliage ; tube of spathe cylindrical, green, obscurely striped with 

 white ; the elliptic blade arches forward, green on the inner sur- 

 face, and brownish-red on the outer; spadix produced into a 

 purplish-red tail, about 1ft long. April L pedate. The large 

 bracts, which sheath the base of the stem, are beautifufly 

 marbled with dark olive green, red, and light green. *. 4ft
