186 Mr. J. Miers on the genus Lycium. 



probable from the record of its being used from the earliest 

 periods by the Persians, Greeks, and Romans for ornamental 

 hedgings. In favourable positions the leaves often attain a size 

 of 2| inches in length, including the petiole, and \\ inch in 

 breadth ; the peduncles are 4 to 6 lines long, the calyx 2 lines, 

 the tube of the corolla 3 lines, the segments of the border 2^ 

 lines, and the stamens extending beyond the mouth of the tube 

 2£ lines ; the berry is from 5 to 8 lines long and 4 lines broad. 

 Intermediate with the globular fascicles upon the stamens, an 

 equal number of tufts of hair are seen on the tube of the 

 corolla, upon the central nervure that runs from the apex of each 

 segment to the base : an excellent analysis of the flower is given 

 in Nees' Flor. Germ. Several varieties, cultivated by gardeners 

 under the names of L. ovatum, Trewianum, carnosum, latifolium, 

 &c., may be referred here*. 



44. Lycium Kraussii, Dun. in DC. Prodr. xiii. 517. — C.B.S. 



Of this species I am unable to form an opinion, not having 

 met with any specimen that corresponds with the description 

 given, as above cited : M. Dunal appears to doubt its being a 

 valid species, and asks whether it may be only a variety of L. 

 cinereum, Thunb. 



45. Lycium rigidum, Thunb. Prodr. 37; Linn. Trans, ix. 152, 

 tab. 14; Dunal in DC. Prodr. xiii. 522.— C.B.S. 



I have not met with any specimen that corresponds with this 

 plant of Thunberg, although M. Dunal describes a specimen from 

 the collection of M. Drege : I infer from that description that it 

 must belong to this section. It is evident however that many 

 Cape plants that have been referred to this species do not belong 

 to it : for instance, the variety 7. angustifolium of M. Dunal [loc. 

 cit. p. 523), from Drege's collection, sub nom. L. rigidum, and 

 which I find also under this name in Sir. W. Hooker's herbarium, 

 is manifestly a specimen of L. Afrum : so also from the same 

 collection a plant distributed under the name of L. campanula- 

 turn, E. Mey., and referred by M. Dunal to L. rigidum, var. 

 /3. latifolium-grandiflorum, from the specimen in Sir W. Hooker's 

 herbarium, is also L. Afrum : it is not unfair to conclude that 

 the other variety, a. lattfolium-parviflorum, belongs to some other 

 species. 



46. Lycium Requieni, Dunal in DC. Prodr. xiii. 520. — Patria 

 ignota.
