DR. DONAIiDSON SMITH'S ACANTHACE^. 413 



The flowers are borne in short crowded few-flowered spikes at the 

 ends of the branchlets. The lower bracts are foliaceous, the upper 

 ones more membranous, narrowly elliptical and narrowed at both 

 ends, and pubescent and glandular-hairy like the sepals; they reach 

 16 mm. in length by 3-3-5 in breadth. The bracteoles are 8-5 mm. 

 long, about f mm. broad. The posterior sepal is 17 mm. by 5-5 -5, 

 the anterior, which is bifid for about one-third from the apex, is 

 16 by 5-5-6 mm., the lateral 13 by 1-5 mm. ; they bear scattered 

 soft white hairs and minute yellow glandular hairs. The corolla- 

 tube is cyliudrical for 8 mm. of its length, then suddenly expands 

 into a funnel 6 mm. long; the upper lip has convex sides, is 17 mm. 

 long, and when flattened 4 mm. broad ; the lower is 18 mm. long, 

 its three lobes are 5 mm. loug, the middle 4 mm., the lateral 5 mm. 

 broad. The stronger stamens are 18 mm. long, the smaller 11 mm. ; 

 the anthers 2-5 mm. The disc surrounding the ovary is 1 mm, 

 high, and has an undulate margin. An unripe fruit was 12 mm. long. 



Leucobarlekia polyacantua Lindau. Turfa and Shebele Kiver, 

 Aug. 1894. 



As the corolla was absent in the specimens from which Lindau 

 described the species {Annicar. 11. Istit. Botan. di Roma, vi. (1896), 

 77), it will be useful to supplement his description from our 

 material. It is small, sparsely hairy on the outside, 10 mm. long, 

 with a narrow tube (3 mm. by scarcely 1-5 mm.) widening into a 

 Convolvulus-like funnel 8-9 mm. broad at the mouth. The margin 

 is undulate, and shows only a very slight indication of division into 

 parts ; it is traversed longitudinally by four sets of 3-4 prominent 

 parallel veins. The small hairy stamens are inserted at the mouth 

 of the tube, which is also pilose. The larger have a curved filament 

 only 1 mm. long, from the top of which are suspended the two 

 fertile anther-cells, which are barely -5 mm. long; the smaller have 

 a filament -5 mm. long ; only one cell is fertile, the other is a small 

 elliptical stalked structure.

The specimen consists of a long almost erect strong woody shoot 

 rooting at the base, nearly 1 metre high, and 3*5 mm. in diameter 

 just above its base, also a shorter more spreading shoot which may 

 have been torn from the base of the longer. The branchlets bear 

 short leafy shoots. The leaves may be 17 mm. long (including a 

 petiole of 3 mm.) and 7 mm. broad ; generally they are smaller. 

 The flowers are almost sessile in the leaf-axils. The bracteoles are 

 1-5 mm. long. The calyx-tube is 10 mm. long, and 2 mm. in 

 diameter at the throat, becoming slightly narrower downwards.
