 clothed with pungent briftles ; their Jloivers axillary, or 

 racemofe with bradeas. See Borago.

 dica; Linn. Sp. PI. 197. Willd. Sp. PI. v. i. 776.

 at the bafe. Seeds without a border. Leaves clafping the 

 Hem. — Native of the Eaft Indies. A tender annual, cul- 

 tivated by Miller, and flowering throughout the fummer 

 and autumn. The Jlem is much branched, rather diffufe. 

 Leaves feffile, obloag, bluntifh, entire, rough with hairs and 

 callous points ; clafping the ftem with their (lightly heart- 

 fliaped bafe. Flowers axillary, folitary, ftalked, drooping, 

 white, pale blue, or reddifh, with five rufty fpots round 

 the mouth. Calyx hairy, each fegment acute, much elon- 

 gated at the bafe. Seeds pale, nearly fmooth. 



2. T. africanum. African Trichodefma. Borago afri- 

 cana ; Linn. Sp. PI. 197. Willd. Sp. PI. v. i. 777. 

 Ait. Hort. Kew. v. i. 296. CynoglofToides africana ver- 

 rucofa et hifpida ; Ifnard as above, t. 10.) — Clufters 

 alternate, terminal. Calyx without auricles. Seeds bor- 

 dered. Leaves ovate, ftalked. — Native of the Cape of 

 Good Hope. A tender annual, cultivated by Miller, 

 flowering \i\ July and Auguft. The whole plant is very 

 harfli and liifpid. Leaves oppofite. Flowers fmaller 

 than the lalt, but much more numerous, pale blue, yel- 

 lowifli about the mouth, with five purplifh ipots. Anthers 

 with long convoluted points. Seeds bordered, fringed.

 auricles. Seeds fmooth, without a border. Leaves nearly 

 feflile, tapering at the bafe. — Native of Ceylon, and other 

 parts of the Eaft Inaies, as well as of New Holland, 

 within the tropic. Dr. Roxburgh fent feeds to fir Jofeph 

 Banks, in 1799. This, like the reft, is an annual plant, 

 flowering in the ftove about July and Auguft. The her- 

 bage is, as Mr. Brown remarks, very variable in its quan- 

 tity of briftles and foft hairs ; the latter, in wild fpe- 

 cimens, arc fometimes very abundant, giv ng the long 



Jlower-Jlalks, and calyx, more efpecially, a hoary afpeft. 

 The leaves are oblong or obovate, moftly oppofite. Cluf- 

 ters leafy. Corolla white and femi-tranfparent. Seeds ovate, 

 grey, fmooth and highly polifhed, like our Common Crom- 

 well. 



TRICHODIUM, received that name from MiclHaux, 

 who conftrufted it out of S;iJ, Tfi'xo;, a hair, and iiioc,form, 

 or appearance, in allufion to the capillary ftalks of the panicle.

 (heaths. Calyx-valves lanceolate. — Common in all gralfy 

 fituations, from Hudfon's bay to Florida, flowering from 

 May to Auguft. Michaux, Purjh. Root perennial. Leaves

 huear-lanceolate, with fmooth (heahs. Calyx-valvs taper- 

 pointed. — On moill hills, and in (hort grafs -meadows, from 

 Canada to Carohna, flowering from June to Aiigufc. Root

 AgroJUs alba, being twice the fize of the foregoing, and 

 much more numerous. 



This, known by the name of Frafer's New American 

 Grafs, was brought from Carolina by that indefatigable 

 coUeftor, in the year 1788. His friend Mr. Walter, in the 

 Flora Caroliniana, extols this grafs as one of the Creator's 

 moft precious gifts, which he himfelf was deftined to make 

 firft known to mankind. Kalm had indeed, long ago, fent 

 a fpecimen to Linnaeus, but without any particidar account 

 of its ufe or diftinftions, fo that his fpecimen remained un- 

 diftingui(hed from other fpecies, which it much refembles. 

 The folitary valve of the corolla led Mr. Walter to refer 

 this plant to the genus Cornucopie, to which it has no other 

 affinity. He was moreover flattered by this name, as con- 

 curring with his own idea of the value of his difcovery. 

 Nor do we doubt the accuracy of his ftatements, pubhihed 

 in Mr. Frafer's Monograph above cited. Neverthelefs, this 

 grafs has difappointed the hopes of European cultivators, 

 and has now totally difappeared. " The places that knew 

 it, know it no more." It is not even mentioned in Mr. 

 Sinclair's elaborate and valuable experimental work, the 

 Hortus Gramineus Woburnenfis, nor by Mr. Dryander in the 

 Hortus Kewenjis, though Mr. Aiton has fupplied the latter 

 defeft in his Epitome. So difiicult is it to cultivate gralfes, 

 in general, away from their native fituations, for any agri- 

 cultural profit, that the difappointment we are obliged to 

 record, is no impeachment of the accuracy of thofe who 

 ftill reckon our Trichodium among the beft grades in 

 America.
