428 Dr Graham's List of Bare Plants. 



limb oblique, 5-cleft, the lowest lobe the largest, crcnatc and revolute, 

 the others subequal, the two uppermost the flattest. Stamens didy- 

 namous; filaments adhering to the tube of the corolla to unequal heights, 

 the two inner the farthest exserted, the others nearly as long as the 

 upper lobes of the corolla; anthers dark, lobes parallel ; pollen white. 

 Pistil rather longer than'the shorter stamens ; style glabrous, and colour- 

 less, except at the apex, where it has a faint tinge, the same as the 

 corolla, its lobes subulate, spreading, subequal. Disk small, round, fleshy 

 supporting the abortive achaenia. 

 The plant was received at the gardens of the Caledonian Horticultural 

 Society, from Mr Low of Clapton in October 1839, and flowered freely 

 during the summer and autumn following, both in the greenhouse and 

 open border, requiring no particular treatment. 



Helichrysum niveum, Grah. 



H. niveum; perenne, caule erecto, subsimplice, scabro ; capitulis maximis 

 solitariis terminalibus, squamis utrinquc niveis conniventibus ovatis 

 mucronulatis ; foliis oblongo-spathulatis, utrinque viridibus, pubescen- 

 tibus, basi in petiolum angustatis, semiamplexicaulibus. 



Helichryscum niveum, Bot. Mag. 3857. 



Description. — Stem (above 3£ feet high) somewhat woody, erect, simple 

 below, corymbose at the top, green. Leaves (7 inches long, nearly 2 

 broad) gradually smaller upwards, scattered, as well as the stem rough 

 without pubescence, sessile, the lower ones obovate and much atten- 

 uated at the base, the upper more nearly elliptical, green on both sides, 

 with a strong middle rib, and four to six principal veins extending nearly 

 to the apex of the leaf, which is entire in the edges. Capitula terminal, 

 on elongated, subsimple, corymbose branches. Involucre large, scariose, 

 of snowy whiteness, spreading into a hemisphere ; scales elliptical, very 

 numerous, imbricated, the outer and inner smaller than the rest, con- 

 cave, none of them radiating, the inner green at the base. Florets very 

 numerous, yellow, cylindrical, all hermaphrodite, 5-toothed. Stamens 

 inserted near the base of the corolla, the apices of the anthers subex- 

 serted. Stigmata revolute, truncated, hairy at the apices. Style colour- 

 less, filiform, its apex projecting above the stamens. Germen glabrous, 

 crowned with a rough pappus, almost plumose, as long as the corolla. 

 Receptacle naked, pitted. 



This large and extremely ornamental species, was raised by Mr Low of 

 Clapton, from seed sent from Swan Kiver by Mr Drummond, late of 

 Cork, and seedlings sent to the garden of the Caledonian Horticultural 

 Society in October 1839, flowered very abundantly during July and 

 August following, forming an exceedingly attractive border plant. 



The species has proved to be perennial, pushing, in the year after flower- 

 ing, many branches from the lower part of the stem. It has not ripened 

 seed at Edinburgh. It has much affinity with the II. macranihum of 

 Bentham, but is distinguished by its large capitula, pure white, cup- 

 shaped involucre, and perennial root. It is in the highest degree worthy 

 of cultivation. 



Mirbelia speciosa, Sieb. 



M. speciosa ; foliis linearibus, mur ronatis, aveniis, sparsis vel subverti- 

 cellatis, marginibus revolutis integerrimis ; floribus in spicam folio- 

 sam, subterminalem, interruptam, dispositis.

 Description. — Shrub branched, slender; branches elongated, bluntly an- 

 gular, having scanty adpressed pubescence, grey and with many small 

 green spots. Leaves scattered or subverticillate, linear, mucronatc,
