128 ORCHIDS OF THE CAPE PENINSULA. 
This species was mistaken by Lindley for S. parvijlorum, Swartz, which 
he had not seen; and his citation of Jacquin’s figure in Hort. Schénbr., 
t. 179, unfortunately added to the confusion, for that is very different 
even from his own description, and is our S. ochroleucum. The 
species varies very greatly in size, and in the length of the leaves, 
which are often much reduced; also in the width of the sepals and 
petals; but the erect and somewhat inflated bracts, and the very large 
free point of the galea are constant marks. 
12. Satyrium Hallackii, Bolus, in Journ. Linn. Soc., vol. xx. 
(1884), p.476.—An erect, glabrous, robust herb, 9-18 in. high. Scape 
straight, thick, leafy; leaves ovate-lanceolate, acute, coarsely nerved, 
sheathing at base, erect and spreading, the lower 4-8 in. long, the 
upper passing into 8 or 4 very erect, acute, strongly-ridged sheaths ; 
spike oblong, very densely many-flowered, 3-5 in. long; bracts lanceo- 
late, the younger erect, the lower erect, then spreading, all longer than 
the flowers; side sepals oblong, subobtuse, a little longer than the 
narrower odd sepal; petals linear, obtuse, all the segments about 4 lines 
long; lip galeate, with a mouth wider than long, sharply keeled at the 
back, with a small acute reflexed point, spurs tapering, about 6-7 lines 
long, shorter than the ovary; rostellum with a lanceolate, acute, 
middle lobe in front, and a wide recess for the gland on each side, 
2-tubercled at base; stigmatiferous lobe of the column short cushion- 
like, wider than its length, marginate at the top.—S. foliosum, and 
var. helonioides, Lindley! Gen. d Sp. Orch. (1888), p. 836, not of 
Swartz. 
Has. In sandy soil, Houts Bay, 100 ft., end of December, Bodkin.—“‘ Cape 
Flats,’’ Pappe, 65!, Zeyher, 1556: apparently not frequent.—Extends eastward to 
Port Elizabeth, Hallack, a form with smaller flowers and relatively longer spurs.— 
(Bolus, 6092; Burchell, 4372, 4379.) 
The flowers are a rosy pink. The species is quite distinct, and 
there is no other on the Peninsula in the least degree resembling its 
thick dense spike of pink flowers, which are as large as those of 
S. marginatum. 
I described the species originally from specimens sent me by 
Mr. R. Hallack from Port Elizabeth. I have since seen plants from 
the Peninsula which have larger flowers and longer bracts; the fore- 
going description, as also the figure, is taken from the latter. 
PuaTtE 29.—Figs. 1, 2, flower, side and front views x 2 diameters; 3, sepals 
and petals, upper side x 2; 4, ditto, under side x 2; 5, column, with one gland 
remoyed ; 6, ditto, side view; 7, section of ovary,—all the latter variously magnified. 
13. Satyrium bicallosum, Thunberg, Prodr. Plant. Capens. (1794), 
p- 6; ib., Flora Cap., ed. 1828, p.19; Swartz, Kongl. Vet. Acad. Handl., 
vol. xxi. (1800), p. 216.—Glabrous, erect, usually very straight, 8-12 in.
