Species novae in Gardener's Chronicle, 3. ser., XLIX (1911) descriptae. 321 



elliptic-oblong or oblong, obtuse or rounded at the base, coarsely cre- 

 nate-serrate, 2— V-\ 2 times as long as their breadth (the lower leaves of 

 a branchlet sometimes elliptic, l x / 2 times as long as their breadth al- 

 most glabrous; lateral nerves not impressed on the upper surface, 

 distinctly raised on the lower, running towards the margin without 

 forming conspicuous loops; primary veins much more conspicuous than 

 the others, running nearly at right angles to the midrib, V 2 — 1 lin. 

 apart. Anthers oblong. Apex of style divided into several distinct 

 branched with capitate stigmas. — 0. Routledgei is at present known 

 only from Uganda, British East Africa, and German East Africa 

 at altitudes ranging from 4,000 feet to 8,000 feet. Mr. M. T. Da we, 

 who collected specimens on Mt. Ruwenzori, described it as a shrub 

 about 20 feet high. It bears strong axillary spines 1 inch long or less. 

 The leaves are alternate, as in all Bixaceae, shortly petioled, elliptic- 

 oblong or oblong shortly tapering to an obtuse apex, obtuse or rounded 

 at the base, coarsely crenate-serrate, 2^ — 4^2 inches long, l l j i —2 l j i 

 inches broad (rather narrower in proportion on young plants), almost 

 glabrous, thinly coriaceous in a dried state; lateral nerves rather oblique, 

 about five or six on each side of the midrib. Flowers borne singly or 

 two together on the old wood, white, fragrant. 2 — 2% inches across. 

 Calyx deeply fourfid, reflexed below the young fruit. Petals about eight. 

 Stamens very mimerous; anthers oblong, jellow. Ovary one-celled; style 

 divided below the apex into about eight capitate branches radially ar- 

 ranged. Fruit globose, woody, indehiscent. 



H4. Iris chrysographes W. R. Dykes, 1. c, p. 362. — Rhizoma gra- 

 «ile; folia lineari-ensiformia, acuta, glauca, V 2 poll, lata; caulis simplex 

 sexquipedalis, foliosus, subfistulosus; spathae 1—2 florae, valis viridibus, 

 acutis, 2—3 poll, longis; pedicellus 1—1 V 2 poll, longus; ovarium tri- 

 gonum, lateribus concavis; tubus latus, Vi P°U- longus; segmenta omnia 

 laete atropurpurea; exteriora obovato-unguicularia, praeter unguem de- 

 pendentia, lineis aureis truneis picta; interiora anguste oblanceolata, 

 oblique erecta. — This new Chinese species is a member of the sibirica 

 ffroup and very closely allied to I. Forrestii (Gardener's Chronicle, June 25, 

 !910, p. 418, fig. 190). It differs from the latter in habit and in flower- 

 colour, the tufts of leaves being much less closely set, and also in the 

 fact that it flowers a week or more in advance of Forrestii. — The stem 

 is about 15—18 inches long, and bears one or two reduced leaves. It 

 is not as hollow as are the stems of I. sibirica or I. Ddavayi; on the 

 ■other hand, it is not wholly filled with pith, but has a distinct channel 

 running down the centre. The stem does not appear to branch, and 

 bears only the terminal head of one or two flowers, borne on long pe- 

 dicels in long, narrow green spathes, 3 inches or more in length. — 

 This Iris was discovered by Wilson in 1908 in China, growing in 

 'hickets to the West of Kuan Hsien in West-Szechuan, at a height 

 •of from 7—11,000 feet. Herbarium specimens bear the number 1,304.
