 orange-brown rays, almost black."

 pinnita, Torr. & Gray. Slender, 3-5 ft. high; Ivs.

 sometimes lobed, the uppermost run together: rays yel- 

 low, often 2 in. or more long. Western N. Y. to la., 

 south to La. B.M. 2310. j. H. Cowen. 



LEPlDIUM (from Greek for little scale ; alluding to 

 the small flat pods). Crueiferm. Cress. Peppergrass. 

 Perhaps 100 species of small herbs (sometimes under- 

 shrubs) in many parts of the world, with very small 

 white fls. There are about 20 native species, mostly 

 western, and several introduced weedy species. The fo- 

 liage and pods have an aromatic-peppery flavor. The 

 foliage of some species is used as salad, and the pods 

 are sometimes fed to tame birds (whence the name 

 "Canary grass"). There are no species of much orna- 

 mental value. 



sativum, Linn. Garden Cress. Annual, 1-2 ft., glau-

 inconspicuous, in an elongating raceme : pods nearly 

 circular, bifid at the apex, winged: Ivs. exceedingly va- 

 rious, but usually the radical ones pinnately divided and 

 subdivided, the central cauline ones 2-3-cleft nearly to 

 the base and the segments entire or toothed, the upper- 

 most simple and entire. W. Asia, but widely dissemi-

LEPTACTtNA (Greek, graceful rays; referring to the 

 Star-like aspectof the flower). Also writteniepfacd'Hia. 

 JHubldcete This includes a shrub from western tropical 

 Africa which should rank among the finest tall hothouse 

 shrubs in cultivation that have large white flowers. 

 The fls. have a slender tube, 4 in. long, and 5 narrow 

 spreading lobes, each 5% in. long and recurved for one- 

 third of their length. As many as 4 fls. are borne at the 

 top of each branch, in the axils of the highest pair of 

 Ivs. The plant might be compared to a giant-flowered, 

 loose-clustered Ixora. It is not yet advertised in 

 America, but seems worthy of a trial in some of our best 

 conservatories. 



The genus contains 6 species, all tropical African 

 shrubs, important generic characters being the large 

 calyx lobes, very long corolla tube, 5 included stamens, 

 style branches free or connate, large, lax stipules, and 

 clustered inflorescence. 



Minnii, Hook. Branching shrub, 6 ft. high : Ivs. 5% 

 in. long, 2% in. wide and larger in proportion, oval, 

 wavy-margined, obtuse, with globose green bodies be- 

 tween the insertions of the Ivs., which are stipules: 

 calyx tube 3 lines long, lobes 1 in. or more long, leafy; 

 corolla silky within, lobes lanceolate; stamens 5, in- 

 cluded: style hairy above, 2-branched. B.M. 7367.

stand drought well in California. The genus has about 

 20 species, chiefly Australian, and has not been mono- 

 graphed since 18G6, in vol. 3 of Flora Australiensis. 

 Shrubs or small trees: Ivs. small, rigid, entire, alter- 

 nate, nerveless or 1-3-nerved: fls. white, sessile, soli- 

 tary or 2-3 at the ends of short branchlets or in the axils 

 of the Ivs.: fls. usually white; stamens numerous. The 

 young shoots are often silky. 



Leptospermum bullatum (see Zi. scoparium below) is 

 an exceptionally good pot-plant for those who can srrow 

 heaths. It is better than L. Imvigatum. Cuttings taken 

 from well-ripened wood in the fall or from young growth 

 in summer root freely under the treatment given Eriea. 

 For a potting, use two parts leaf-mold and one of sand. 

 Plunge the pots outside during the summer in the full 

 sunlight. The plants make a straggling growtli. unless 

 trimmed into shape. By fall they will be covered with 

 buds, but it is impossible to force them into bloom for 

 Christmas. Keep the plants in a cool house with Ericas 

 or Azaleas until the latter part of February or March, 

 and then give them a little more heat, say 55° to C0°. 

 The plants will soon be a mass of white flowers. L. bul- 

 latum does not grow rapidly, but, like Epacris, as it 

 grows older it makes fine specimens. It has tough foli- 

 age, stands much hard usage, and when in bloom attracts 

 plant-buyers. It deserves greater popularity. 

 A. Ovary usually 10-celled.

 This includes some yellow-fld. composites, with much- 

 divided foliage like Cosmos. They are 7 species of 

 herbs and subshrubs, all from California except L. Art- 

 nonica. They are the representatives of Coreopsis on 

 the western side of the continent, but have mostly pis- 

 tillate rays and always a ring on the tube of the disk-
