This species of the genus Eucalyptus, a genus well characterized from the singular operculum, which, instead of a corolla, defends the infantile fructification from external injuries, is a native of New South Wales; and was introduced, by seeds from that country, into our gardens, along with some other Eucalypti, several years ago; but has never flowered in Britain until the present summer, in Lady de Clifford’s collection at Paddington, where our drawing was made in July last. It is a shrub of considerable size, and handsome growth and foliage; and its younger shoots droop considerably, after the very elegant manner so much admired in the weeping willow. But the most singular trait in the plant is its tardy and protracted mode of flowering. It has already shown flowers, which it will not expand until next July: they are scarce half the size they will then be, and have upon the tip of the large calyptra one of a far smaller size, but similar in shape, and which will soon fall off, as will also the large one, a little previous to the expansion of the stamina next July. It requires a great deal of root-room, and rich earth; is a very hardy green-house plant, and has hitherto been propagated by imported seeds only. [Illustration] PLATE CCCCI. SERRATULA SPICATA. _Spiked-flowered Saw-wort._ CLASS XIX. ORDER I. _SYNGENESIA POLYGAMIA ÆQUALIS._ Tips united. Æqual Polygamy. ESSENTIAL GENERIC CHARACTER. CALYX subcylindricus, imbricatus, muticus. EMPALEMENT nearly cylindrical, imbricated, without awns. SPECIFIC CHARACTER, &C. SERRATULA, foliis linearibus, basi ciliatis, floribus sessilibus lateralibus spicatis, caule simplici. _Gmel. Syst. Nat. 2. 1185.--Ait. Hort. Kew. 3. 138._ SERRATULA, with linear leaves, ciliated at the base, sessile lateral spiked flowers, and a simple stem. REFERENCE TO THE PLATE. 1. A radical leaf. 2. The empalement spread open. 3. A floret. 4. The same, cut open. 5. The seed-bud and pointal. The Serratula spicata is a native of Carolina; but has been cultivated in the gardens of this country ever since the year 1732; notwithstanding which it is by no means a frequent plant in collections; which I should conceive arises from its being rather difficult to increase.
