ovate, often tipped with black ; intermediate ones longer and less 

 ovate ; those of the inner rows becoming gradually more elon- 

 gated ; the innermost (next the flowers) being pale, oblong -linear, 

 and about 1 inch in length. Receptacle lactescent, nearly flat, 

 naked, marked with hexagonal spaces, in the centre of each of 

 which is a depression for a flower. Pappus, in aestivation, closel/ 

 applied round the conical bud, its hairs, when expanded, about \^ 

 inch long, reaching nearly to the tip of the corolla, arranged in 

 several rows ; these hairs are unequal in length, are beautifully 

 serrated, of a pale orange colour, persistent, and spread much 

 when the corolla falls. Corolla smooth, regular, tubular, and 

 somewhat funnel-shaped, If inch long, of a pale orange colour be- 

 low, and becoming darker above, divided at the apex into five re- 

 volute and circinate narrow segments of a dark orange colour, 

 about ^ an inch long when unrolled. Filaments smooth, colour- 

 ed, inserted into the upper part of the corolla between the seg- 

 ments, arching over the mouth of the corolla to join the anthers at 

 the upper part of their lower third. ^n^Aens about an inch long, 

 two-lobed, exserted, bifid at the apex, with a long bipartite pro- 

 cess below ; pollen three-lobed. Style cylindrical, extending nearly 

 I inch beyond the corolla, and about \ of an inch beyond the an- 

 therine tube, undulated at its lower part. Stigma bifid, hairy on 

 the inner side of the lobes, which close after the application of the 

 pollen. Achcenium [Cypsela) in the young state triangular, | of 

 an inch long, of a green colour, with a short yellowish beak at the 

 summit. 



The plant appears to have been sent to the Edinburgh Garden some 

 years ago from Kew, where it is also flowering this season. The 

 capitula are very showy, and the plant is a desirable one for a 

 stove. It has been flowering since the beginning of February, 

 and at one time there were six large capitula expanded. After 

 the flower falls, the spreading pappus presents a remarkable ap- 

 pearance on the tree.
