Mr. Brown near Port Jackfon. He is not quite confident 

 of its being a diftinft fpecies from the laft. 



^.X. minor. Lefler Yellow-gum. Br. n. 5. — " Stem 

 none. Leaves triangular ; flat in front ; rather concave 

 beyond the middle. Stalk many times longer than the fpike. 

 Bradeas fcarccly longer than the tufts of flowers, all, like 

 the corolla, beardlefs."— Gathered by Mr. Brown, in New 

 South Wales. The fpiie of this fpecies meafures from five 

 to eight inches. Bro<wn. 



6. X. braatata. Long-brafteated Yellow-guni. Br. n. 6. 

 — " Stem none. Leaves triangular ; below the middle fome- 

 what elevated in front ; beyond it rather concave. Stalk 

 many times longer than the fpike. Brafteas fubtending the 

 tufts twice or thrice the length of the flowers, lanceolate and 

 divaricated, all, like the corolla, beardlefs." — From the 

 fame country. 'The fpike is only from three to fix inches in 

 length. Brown. 



•J. X. Pumilia. Dwarf Yellow-gum. Br. n. 7.—" Stem 

 none. Leaves below the middle flattilh, with a (lightly ele- 

 vated ridge on both fides ; beyond it triangular and chan- 

 nelled. Stalk many times longer than the ovate fpike. 

 Brafteas nearly equal, beardlefs as well as the corolla." — 

 Gathered by Mr. Brown, in the tropical part of New Hol- 

 land. The Jlower-Jlalk itfelf is, in this fpecies, only a foot 

 high. Broivn. 



XANTHOXYLUM, received its name from governor 

 Cidwallader Colden, becaufe of the yellow hue of the 

 wood, to which favflo;, yellow, and |i;?,o;, wood, alludes. We 

 make no fcruple to follow the example of profefTor Martyn, 

 in reftoring the proper orthography ; nor is it requifite to 

 burthen our readers with a perpetual indication of the ori- 

 ginal blunder, under every fpecies, though that blunder has 

 the fanAion of Linnaeus, and perhaps of all the authors, 

 except Martyn, that we may have to quote. They gene- 

 rally write the word Zanthoxylum, or Zanthoxylon. — Linn.

Gen. Ch. correfted. Male, Cal. Perianth very fmall, 

 in three or five deep, concave, rather acute fegments. 

 Cor. Petals three or five, oval, ereft, concave, thrice the 

 length of the calyx. Stam. Filaments three or five, awl- 

 fhaped, ered, longer than the petals ; anthers roundifli, two- 

 lobed, furrowed. 



Female, Cal. like the male, inferior, permanent. Cor. 

 like the male, deciduous. Pifl. Germens from two to five, 

 roundifh, each terminating in an awl-fhaped ftyle, longer 

 than the petals ; ftigmas obtufe. Peric. Capfules from 

 one to five, (lalked, each of one cell, and two coriaceous 

 valves, burfting at the inner margin. Seeds folitary, round- 

 ifh, poLfhed, pendulous from an upright briftle-fhaped 

 ftalk. 



Efl". Ch. Male, Calyx in three or five fmall deep feg- 

 ments. Petals three or fire. 



Female, Calyx like the male, inferior, permanent. Petals 

 three or five. Capfules from one to five, of two valves, 

 and one cell. Seeds folitary, pendulous. 



Obf. This genus is diftinguifhed from Fagara, (fee 

 that article,) by having feparated^owifrj-, either three-cleft, 

 or five-cleft, and pendulous feedj. Botanifts appear to 

 have miftaken its real charader, taking the corolla for a 

 calyx. To this error Linnaeus and Duhamel led the way, 



and Juflieu, Willdenow, and others, have followed them. 

 Yet Linnaeus in his Gen. PL fubjoins to his generic de- 

 fcription a more corred ftatement, altogether fuperfeding 

 the former ; and Willdenow admits fpecies from Swartz, 

 whofe petals by their prefence contradid his effential cha- 

 rader. We have not feen living fpecimens of Xantboxylum, 

 but the defcriptions of Browne and Swartz leave little 

 doubt of the corrednefs of the above charaders. We are 

 much tempted to unite the two genera in queftion, but as 

 they really have not been fufficiently inveftigated, and 

 Goertner feems to have difcovered a diftindive mark of 

 XanthoKylum, in the ftalked pendulous y^fc/x, we leave them 

 for future inquiry. The whole genus it ftirubby or arbo- 

 reous, with alternate, pinnate, foraetimes only ternate, en- 

 tire, or fomewhat crenate leaves, and cluftered, or panicled, 

 f.owers. The Jlem is, in moil inftances, armed with 

 prickles, that are fometimes very formidable. The wood is 

 hard, and ferviceable for many purpofes. 

 Sed. I. Stem without prickles.

 fule feldom more than one perfeded, with two internal, as 

 well as external, valves, and one orbicular, black, (hining
