there can generally be pointed out a very short scape, only one or a couple of mm. 

 long. Moreover, this subspecies is characteristic in having the leaves long and rather 

 vigorous, of about the same length as the scape, viz. 6 — 9 cm. The leaves are generally 

 3- or 4- rarely 5-pinnate. The petiole, which is slightly channelled, is — like the scape — 

 more os less distinctly erect, not curved as is frequent in the typical species. The pinnae 

 are generally not opposite, but mostly alternate down the rachis. The leaflets are attach- 

 ed by a distinct, narrow node, which is very fragile, at any rate when dried, and is 

 apt to break, so that the leaflets fall off. In preserved material of this one, as also of the 

 typical species, all, or nearly all, of the pinnae will generally have fallen off, the rachis 

 only being left. Thus in Bunge's authentic specimens nearly all of the leaflets had fallen 

 off. The juncture of the leaflets, however, are, distinctly visible in the small, inflated 

 knots. The leaflets themselves are rather fleshy, linear, straight, or slightly curved, 

 about 2 mm. broad, and 12 — 25 mm. long, nearly equally narrow throughout their 

 length, tapering towards the base and summit, gradually pointed and acute, but never mu- 

 cronate . The margin of the leaflets is distinctly revolute, frequently so much as to make 

 the margins touch each other, whereby the under side of the leaf is at times complety 

 shut in. It is to be supposed that this more or less strongly marked recurvation of the 

 margins is dependent on the turgor, and that this plant, growing on very hot, dry, sunny 

 Devonian sandstone cliffs in a marked steppe climate, has through this, a means of re- 

 gulating the transpiration. The upper side of the leaflets is sparingly pubescent, some- 

 times completely glabrous; the margin is always much and distinctly ciliate, the under 

 side always completely glabrous, whereby the subspecies caulescens is also distinct 

 from the typical species, recorded to be hairy beneath. The stipules are small, membra- 

 nous, adnate to the petiole, the subobtuse apex only being free, and distinctly ciliate. 

 The scape is of about the same length as the leaves; 6 — 9 cm. long, villous-pubescent, 

 with white, appressed hairs, occurring much more sparingly than in the typical spe- 

 cies, the very short scapes of which are always rather densely hairy. The bracts 

 are 7—8 mm. long, mostly of a green colour, sometimes more pallid and membranous, 

 always nerveless, oblong-ovate to broadly lanceolate, glabrous, only ciliate. Only very 

 rarely there are to be found on the bracts some few white hairs, while, in the 

 typical species, they are always densely and distinctly pubescent. The calyx is membra- 

 nous, of a hght yellowish brown, inflated, 12^15 mm. long, with equally large, very 

 narrow, mucronate teeth, the length of which is 4—5 mm. The calyx is rather densely 

 pubescent, with long, white hairs, intermixed with finer, shorter, curved, nearly black 

 hairs. Similar short, black hairs are also to be found here and there on the scape, but 

 are here of very rare occurrence, and nearly exclusively near the upper end. The pedi- 

 cels are very short, 2—4 mm. long, so that the flowers, to be found in a number of 1—3, 

 become densely congested. The pedicels are rather densely pubescent, Uke the calyx. 

 The flowers are comparatively large. As all of the specimens collected were already past 

 flowering, I cannot express any opinion on their colour. Owing to the ripening of the 

 fruit, however, the corolla is broken off by the pod gradually growing out, and remains
