The present species is a weak shrubby plant, flowers freely, and succeeds with the treatment of the other eternal flowers, and is propagated in the same manner: and was lately raised from Cape seeds at our never-failing source of rare plants, the choice collection of G. Hibbert, esq. where the figure here given was made in May last. It is very closely allied to X. argenteum of our 327th plate, which is the X. paniculatum of Thunberg and the younger Linnæus. [Illustration] PLATE CCCLXXXVIII. MESEMBRYANTHEMUM INCLAUDENS. _Unclosing-flowered Fig-Marygold._ CLASS XII. ORDER IV. _ICOSANDRIA PENTAGYNIA._ Twenty Chives. Five Pointals. ESSENTIAL GENERIC CHARACTER. PETALA valde numerosa, linearia, basi cohærentia. PETALS very numerous, linear, cohering at the base. SPECIFIC CHARACTER, &C. MESEMBRYANTHEMUM, foliis triquetris lævibus perviridibus, carinâ gibbosâ, corollis inclandentibus, petalis interioribus valde abbreviatis imbricatisque. FIG-MARYGOLD, with triquetrous smooth deep green leaves, with a gibbous keel, unclosing flowers, and interior petals extremely abbreviated and imbricated. DESCRIPTIO. M. mutabili nobis affinis, sed species valde distincta: differt in his, foliis lævioribus, et longe viridioribus, minusque mucronatis, marginibus sæpius plus minusve purpureis: floribus speciosis semper apertis; nec inconspicuis, nocteque clausis; saturatissime et vivacissime rubicundis, petalis cuneato-linearibus, latis in hoc genere, apicibus erosis; interioribus (petalis) maxime abbreviatis, imbricatisque quasi in stellam. _Calyx_ subanceps, 5-fidus, membranis rubro punctatis. _Filamenta_ recondita, brevissima omnium (vix linearia), alba, basi purpurea. _Antheræ_ albidæ, circiter longitudinem filamentorum. _Styli_ 5, erecti, pergrossi, virides, altitudine antherarum. Capsulam non vidi. _H._ REFERENCE TO THE PLATE. 1. The empalement, seed-bud, chives and pointals. 2. The same cut perpendicularly, to show the insertion of the chives and pointal. Our figure represents a perfectly new and nondescript, and at the same time very ornamental species of Mesembryanthemum: each flower possesses the valuable property of lasting about ten days in beauty, and never closes after being once expanded: a circumstance of exceeding rare occurrence in this very extensive genus; no fewer than 214 distinct species of which we have now a knowledge of[C]. M. inclaudens rises with a branched, shrubby stem, to the height of 10 or 12 inches, and is cultivated in the same manner, and propagated with the same facility, that is common and well known in this tribe: they are all very hardy green-house plants; require in winter as much air as possible, if frost is but avoided; strike freely from cuttings; are great lovers of hot, sunny and sheltered situations, when out for the summer; and are better not watered over their heads, but at the roots only.
