than in the laft, more villous than in the foUowiiifj, and not 

 downy. The paniclcd inflorefcence diftinguifhcs it from both. 

 Flowers red, on villous Italks. 



4. S. tomentofa. Scarlet Spirxa. Linn. Sp. PI. 701. 

 Ait. n. 3. Purlh n. 2. " Schmidt Arb. v. i. 52. t. 51." 

 (Ulmaria pentacarpos, &c. ; Pluk. Phyt. t. 321. [•. 5-)— 

 Leaves ovate, unequally lerratcd ; downy and white be- 

 neath. Clufters compound, downy.— Native of North 

 America ; a hardy (hrub in our gardens, flowering towards 

 autumn, and juftly admired for its Isright red Jlowers, and 

 the white downincfs of the backs of its leaves- In other re- 

 fpefts it much refemblee S. J'aUcifolia. 



c. S. argentea. Silvery Spirsea. Linn. Suppl. 261. 

 Willd. n. 5. — Leaves wedge-ftiaped, furrowed, lomewhat 

 plaited; filky on both fides; ferratcd at the extremity. 

 Clufters compound. Capfules fringed. — Sent from New 

 Granada by Mutis to Linnaeus. The copious filvery leaves, 

 about an inch long, render this a very elegant (hrub. The 

 clufters are numerous at the ends of the branches, but do not 

 confift of many Jlowers. The germens and capfules are bor- 

 dered with long hairs. 



6. S. alplna. Alpine Small-leaved Spiraea. Pall. Rod. 

 V. I. p. I. 35. t. 20. Willd. n. 6. — Leaves linear-lanceo- 

 late, partly toothed, very fmooth. Flowers corymbofe. — 

 Native of cold woody mountains in Siberia, near the lake 

 Baical. A fmall, fpreading, branching yXrwi, whofe bark 

 fplits into long threads. The leaves are hardly an inch long, 

 and very narrow. Flowers white, in fmall downy corymbs, 

 folitary at the end of each branch. 



7. S. hypericifolia. St. John's-wort Spirsea, or Italian 

 May ; commonly called Hypericum frutex. Linn. Sp. PI. 

 701. Ait. n. 4. Purfh n. 3. " Schmidt Arb. v. i. 55. 

 t. 56." Bocc. Muf. 137. t. 96. (Pruno fylveilri affinis 

 canadenfis ; Pluk. Phyt. t. 218. f. 5.) — Leaves obovate, 

 entire. Umbels feffile. — In dry fwamps of Canada and 

 New York, flowering in May. Purjh. This (hrub, cul- 

 tivated for near 200 years pall in our Englifli gardens, and 

 afferted to be of American origin, is no lefs apparently wild 

 on all the hills of Umbria, between Terni and Trevi, as 

 Boccone long ago mentioned. (See Sm. Tour, ed. 2. v. 2. 

 322.) It is frequently called in England Italian May. 

 The leaves are an inch long, refembling feme fpecies of 

 Hypericum. Flowers white, copious and very pretty, in 

 fmooth lateral umbels. 



8. S. chamsdrifolia. Germander-leaved Spiraea. Linn. 

 Sp. PI. 701. Ait. n.5. Purfli n. 4. Pall. Rofl'. v. i. 

 p. I. 32. t. 15. — Leaves obovate, fmooth, cut, and fer- 

 rated. Corymbs ftalked. — Native of Siberia and Hungary. 

 Hardy with us, flowering in June and July. The leaves 

 are green, or (lightly glaucous, on both fides, an inch, or 

 rather more, in length. Flowers white, rather bigger than 

 the laft, nearly umbellate. Branches angular. 



9. S. ulmifoiiH. Elm-leaved Spirxa. Scop. Carn. v. i. 

 349. t. 22*. Willd. n. 9. Ait. n. 6. (S. chamsdri- 

 folia; Jacq. Hort. Vind. v. 2. 66. t. 140.) — Leaves ovate, 

 fmooth, doubly ferrated ; glaucous beneath. Corymbs 

 raceraofe, elongated, on long ftalks. — Native of Carniola 

 and Siberia. Cultivated for about 30 years paft in our 

 gardens, flowering in June. A (hrub larger in all its parts 

 than the foregoing, efpecially the Jowers, which are rather 

 racemofe than corymbofe. The leaves are an inch and a 

 half long, on ftalks one-third that length. 



10. S. betulifolia. Birch-leaved Spirxa. Pall. Rolf, v. i. 

 p. I. 33. t. 16. Purfli n. 5. — Leaves broadly ovate, 

 Imooth, deeply ferrated, on fliort ftalks. Corymbs com- 

 pound, level-topped Native of Siberia; and, according 



to Mr. Pur(h, of the mountains of Virginia, flowering from 



May to July. He defcribes it as not above a foot high ; the 

 Jlowers tinged with red, and aflerts it to be very dillinft from 

 the laft, to which Willdenow refers Pallas's fynonym. The 

 leaves appear to be much broader than in the ulmifolia, 

 with (horter thicker fostjialks, and the injlorefcence more 

 compadt. 



11. S. crenata. Hawthorn-leaved Spirxa. Linn. Sp. 

 PI. 701. Ait. n. 7. Pall. Rolf. v. i. p. i. 35. t. 19. 

 (Oxyacantha anguftifolia non fpinofa ; Barrel. Ic. t. 564.) 

 — Leaves obovate, acute ; toothed at the extremity. Co- 

 rymbs lateral, crowded, (talked. — Native of Siberia, Tar- 

 tary, Hungary, and Spain. Cultivated by Miller in 1739, 

 and frequently met with in curious (hrubberies, flowering in 

 May. The leaves vary much in (5/,e and (hape, but are al- 

 ways ftrongly toothed, or jagged, at the end. When fmall 

 they are often three-ribbed, but that charafter is not fo con- 

 ftant as to make a fpecific difference. Flowers white, in 

 copious, (hort, lateral, leaflefs clufters. Willdenow fuf- 

 pedls the Spanifh variety may be a diftinft fpecies, but we 

 find our garden plant fo variable, that the line of diltinftion 

 is fcarcely to be drawn. A comparifon of living fpecimens 

 mult decide the queftion. 



12. S. trilobala. Three-lobed Spirxa. Linn. Mant. 2. 

 244. Willd. n. II. Ait. n. 8. Pall. Rolf. v. i. p. i. 

 t. 17. — Leaves roundi(h, fomewhat heart-fliaped, bluntly 

 lobed, toothed. Umbels terminal. — Native of mountains 

 in Siberia. A hardy (hrub with us, introduced by fir J. 

 Banks in 1801, but not yet come into general culture. It 

 flowers in May. The leaves are fmooth, not unlike thofe 

 of a goofeberry in (hape. Flowers white, copious, and 

 handfome. 



13. S. thaliaroides. Meadow-rue-leaved Spirxa. Willd. 

 n. 12. Ait. n. 9. Pall. Rod. v. i. p. i. 34. t. 18. — 

 Leaves obovate, obtufe, fomewhat three-lobed. Umbels 

 lateral, felTile. — Native of the alps of Dauria. Flowering 

 at Kevv in May. A pretty fpecies, with fmall leaves, very 

 glaucous beneath. Flowers white, fmaller than the laft, 

 and lateral, not terminal. 



14. S. opulifolia, Virginian Guelder-rofe. Linn. Sp. 

 PI. 702. Ait. n. 10. Purfti n. 6. " Schmidt Arb. v. i. 

 52. t. 52." (Euonymus virginiana, ribefii folio, capfulis 

 eleganter buUatis ; Comm. Hort. v. i. 169. t. 87.) — Leaves 

 ovate, three-lobed, ferrated, fmooth. Corymbs terminal, 

 denfe, braAeated. Capfules polKhed, inflated. — On the 

 banks of rivers, particularly among the mountains, from 

 Canada to Carohna, flowering in June and July. Generally 

 known by the name of Nine-bark. PurJh. Cultivated by 

 bifhop Compton, and now common in (hrubberies, forming 

 a fmall tree, with much refemblance to the Common 

 Guelder-rofe. Flowers white, fomewhat like Hawthorn. 

 Capfules tumid, fmooth, of a fliining brown. Calyx more 

 or lefs downy. 



15. S.capiiata. Capitate Spirxa. Purfli n. 7. — "Leaves 

 ovate, (omevvhat lobcd, doubly toothed ; reticulated and 

 downy beneath. Corymbs terminal, denfe, fomewhat capi- 

 tate, on very long (talks. Calyx downy." — Found by 

 Mr. Menzies, on the north-welt coait of America, flower- 

 ing in June. Gathered alfo on the Columbia river by 

 governor Lewis. Pur/h, 



16. S. aritefolia. Beam-tree-leaved Spirxa. — Leaves el- 

 liptic-oblong, fomewhat lobed, toothed ; pale and villous 

 beneath. Clutters compound, panicled, terminal, downy. 

 — Gathered on the north-welt coaft of America, by Mr. 

 Menzies, to whom we are obliged for fpecimens. It feems 

 not noticed by Mr. Purfli. Perhaps this fpecies ought, on 

 account of its panicled very c;<mpound inflorefcence, to be 

 ranged near falicifolia and tomentofa. The leaves are lobed 



like
