The measurements given in the above description are from Kotschy, 489, an 

 unusually tine example, and the size of the leaves, calyx and Howers, runs down in other 

 examples till we reach A. Gaed, Lindau, from 5000 ft. alt., where the dimensions are 

 scarcely § those of Koischy, 489. As regards hairiness, the examples become usually 

 glabrate except the inflorescence ; but in Steudner, 1532, the well-matured leaves are 

 densely woolly beneath with several-celled white hairs, and have similar hairs 

 scattered above. There are examples intermediate in hairiness between this example 

 and the ordinary .4. arboreus; I cannot characterise even a variety here; the adjacent 

 species are equally variable as to hairiness. 



2. A. eminens, C. B. Clarke. Glabrate, C-8 ft. high. In- 

 florescence pubescent. Leaves 10 by 4: in., pinnatifid, spinous, petiole 

 hardly any. Spike 9 by '2h in. ; bracts scarcely 1 in. long, ovate, 

 hardly acute, with several spines on the margin ; bracteoles \ in. long, 

 subulate, not spinous. Calyx soft, not spinescent ; posticous segment 

 li by nearly J in., broadly oblong, not lanceolate upwards ; anticous 

 segment the same size and shape, 2-nerved, minutely emarginate at the 

 tip ; 2 inmost segments f-J in. long, lanceolate. Corolla 2 in. long, 

 purple {Scott- Elliot). Ovary large, with hemispheric cap ; style in the 

 lower half densely short hairy.

This species, usually 3 ft. high, is very close to A. arboreus. The flowers and 

 capsules are larger than in many examples of A. arboreus. In the type examples, the 

 leaves are " caudate." As to hairiness, in Scott-Elliot, 4619, one inflorescence is very 

 sparingly pubescent, in the other the bracts are conspicuously hirsute with many patent 

 long white hairs.
