SourH Arrica: without locality, cultivated specimen !_ 
I am indebted to the courtesy of Dr. A. Zahlbruckner, Head of the Botanic 
Department of the Vienna Hofmuseum, for the opportunity of examining the type 
specimen of this very rare plant, of which only a single individual is known. 
This was introduced from South Africa in the latter part of the 18th century and 
has been in cultivation in the Imperial Garden at Schénbrunn for over 100 years 
and was exhibited alive at the International Botanic Congress at Vienna in 1905. 
Dr. Zahlbruckner states that it has never produced seeds, and all efforts to 
propagate it have hitherto failed ; no botanical collector seems to have refound it, 
so that the locality whence it came is unknown. Possibly, however, it may be 
only an individual variation of F. glabra, since with the exception of the relative 
proportions in size of the coronal parts, I do not find any great difference in floral 
structure ; the appearance and pubescence of the plant are, however, decidedly 
different, and there does not seem to be the same tendency to produce short leafy 
branches in the axils of its leaves as there is in F. glabra. I have therefore 
maintained them as distinct species, leaving future discoveries to prove or disprove 
the correctness of this view. 
Imperfectly known species. 
6. F. sessiliflora (Schlechter in Engl. Jahrb. xx. Beibl. 51, 44) ; 
stem woody, glabrous ; leaves erect or erectly spreading, }-13 in. 
long, 4—7 lin. broad at the middle, lanceolate or lanceolate-oblong, 
acute, tapering into a very short petiole at the base, often revolute 
or undulate on the margins, glabrous ; flowers few, sessile, clustered 
in the axils of the leaves (/ lateral at the nodes); sepals deltoid- 
lanceolate, much shorter than the corolla, thinly puberulous, with 
mealy cushions (‘“ farinoso-pulvinatis”) ; corolla-lobes erectly spread- 
ing, flexuose, scarcely 3} lin. long, linear-ligulate, somewhat obtuse, 
thinly puberulous on both sides ; corona tubular, with 5 short trifid 
lobes at the top, having the lateral teeth a little shorter than the 
middle one ; within the tube arise 10 erect filiform processes in front 
of each other, in two series ; the upper series much exceeding the 
tube, with their margins decurrent as 5 pairs of parallel keels ; the 
lower series half as long, scarcely equalling the tube. WN. H. Br. in

Karanart Reaion: Transvaal ; near Klipdam, 4500 ft., Schlechter, 4493. 
I have not seen this species. In the British Museum a specimen of F. tugelensis 
has been named F. sessiliflora by Dr. Schlechter, whilst in the Journal of Botany, 
1898, 487, he states that it is the same as F. undulata, but neither of these totally 
different species corresponds to his description of F. sessiliflora. 
7. F. Comaru (N. E. Br.); tuber very large and fleshy, 
elongated, 3-6 in. thick, with a woody neck or permanent stem 
2-3 lin. thick, from which the branches are produced ; branches
