marked with a tranfverfe green or brownifh line, and all 

 nearly equally fpreading, though the central one is rather 

 fmaller than the other two. 



3. W. hirfuta. Narrow-leaved Hairy Wachendorfia. 

 Thunb. Prodr. 12. Willd. n. 3. Vahl n. 3. Ait. n. 3. 

 (W. villofa; Andr. Repof. t. 398.) — Leaves linear-fword- 

 fhaped, hairy. Panicle rather oblong. — Gathered at the 

 Cape by Thunberg, from whom we have a fpecimen. It 

 flowers in our green-houfes in June, but is not common. 

 Mr. Andrews received his fpecimen from Mr. Vere's garden 

 at Kenfmcrton-gore, where the plant flouriflied abundantly 

 under the care of Mr. W. Anderfon, now curator of the 

 Chelfea garden. This fpecies is well diftinguifhed by the 

 narrownefs, and remarkable long fhaggy white hairs, of its 

 leaves. The flem and panicle alfo are rather more hairy than 

 in the preceding, and the form of the latter is more elon- 

 gated, lefs corymbofe. Flo'wers large and handfome, bright 

 yellow ; externally tawny ; their central uppermoil petal 

 concealed in front by the two next, which meet before it : 

 they are all broadilh-obovate, fliaggy at the back. 



4. W. brevifolia. Short-leaved Hairy Wachendorfia. 

 Ait. n. 4. Ker in Curt. Mag. t. 1166. (W. hirfuta; 

 Ker in Curt. Mag. t. 614? Sifyrinchium ramofum Kthio- 

 picum, fohis plicatis nervofis et incanis, radice tuberofa 

 phoenicea ; Breyn. Cent. t. 37. Rudb. Elyf. v. 2. 13. 

 f. 10.) — Leaves elliptic-fwordfhaped, hairy. Panicle fpread- 

 ing. — Native of the Cape, from whence, according to Mr. 

 Aiton, it was introduced into the Enghlh green-houfes, in 

 1795. It flowers in March or April. We have feen no 

 fpecimen, and therefore can only prefume, not alfert, that 

 the dingy-flowered plant, figured in t. 1 166 of the Botanical 

 Magazine, and the brighter yellow one in t. 614 of the fame 

 work, are varieties of each other. The fliortnefs of the 

 leaves, compared with their great breadth, diftinguiflies the 

 prefent fpecies. The two lateral upper petals nearly conceal 

 the central one, feen in front, according to Mr. Ker's juft 

 remark, by which the powers obvioufly differ from thofe of 

 W. panlcitlala. 



5. W. tenella. Linear Smooth-leaved Wachendorfia. 

 Thunb. Prodr. 12. Willd. n. 4. Vahl n. 4. — " Leaves 

 linear, three-ribbed, fmooth. Panicle fpreading, fomewhat 

 compound." — Gathered at the Cape by Thunberg, whofe 

 fpecific charaSer is all we know of this fpecies. 



6. W. gramima. Grafs-leaved Wachendorfia. Thunb. 

 Prodr. 12. Willd. n. 5. Vahl n. 5. ( W. graminifolia; Linn. 

 Suppl. loi.) — Leaves fword-fhaped, channelled, fmooth. 

 Panicle fpreading, compound. — From the fame country. 

 Thunberg confiders this as the rareft Cape plant of its tribe. 

 He has favoured us with a fpecimen of the panicle only, not 

 having a duplicate leaf. The Injlorefcence is hairy, as in all the 

 fpecies we have feen ; the branches of the panicle racemofe, 

 fomewhat zigzag. Floiuers yellow ; externally tawny. Ger- 

 men very hairy, but tliis feems to be more or lefs the cafe 

 with the whole genus, the fpecies of which differ lefs in 

 their parts of fruftification than ufual. 



Wachekdorfia, in Gardening, funiifhes plants of the 

 exotic flowering perennial kind, for the green-houfe, in 

 which the fpecies cultivated are, the fimple-llalked wachen- 

 dorfia ( W. thyrfiflora) ; the panicled wachendorfia ( W. pa- 

 niculata) ; and the hairy wachendorfia ( W. hirfuta). 



The firft is a red thick tuberous-rooted plant of the 

 flowering kind. 



The fccond fort has a creeping tuberculated root, and is 

 fingle-flowered. 



The lafl chiefly differs from the aboi*e in the hairinefs of 

 ks leaves, and its long reddifh-brown ftem. 



Method of Culture. — Thefe plants may be incpeafed by 

 offsets, taken from the heads of the roots, in the beginning 

 of autumn, planting them in pots filled with foft loamy 

 earth, mixed with a little fea-fand ; and when the feafon 

 proves dry, placing them fo as to have only the morning 

 fun, until the offsets have taken new roots, when they muft 

 be placed in a fheltered fituation, fo as to have the full fun. 

 On the approach of frofts, they fhould be placed in frames, 

 and managed as plants of the tender kind. They are alfo 

 fometimes capable of being propagated by root-fuckers and 

 feeds. 



The fecond fort is very impatient of cold, and feldom 

 flowers in this climate. 



They produce variety among other potted plants of the 

 green-houfe kind, in collections of that fort.

 it Wachovia after an eftate belongmg to count Zinzendorf,

WACKE, or Wacken, in Mineralogy and Geology, a 

 name given to a rock nearly allied to bafalt, and which may 

 properly be regarded as a more foft and earthy variety of 

 the latter rock : it paffes both into bafalt and green-ftone. 

 See Tr.\p. 



Its colour generally inclines to greenifh-grey, brown, or 

 black ; it is opaque and dull, yields eafily to the knife, and 

 has rather a greafy feel. It occurs with bafalt and green- 

 llone in beds, or mountain maffes, and graduates into the 

 above-named rocks. Wacke is fometimes compact, and fome- 

 times veficular or amygdaloidal. At Calton-hill, near Edin- 

 burgh, it is porphyritic, containing diflinct cryftals of augite 

 and felfpar. 



The wacke which is faid to occur in mineral veins, we 

 fufpefted to be indurated green earth. The fpecific gravity 

 of wacke varies from 2.617 '^° 2.887. 



Wacke is clafled with fimple minerals by Werner, but is 

 confidered by Cordier as a compound rock of volcanic ori- 

 gin, and compofed of minute cryilals and particles of augite, 

 felfpar, and the other minerals which are found in the dif- 

 ferent varieties of lava. ( See Volcanic ProduBs at the end
