186 ORCHIDS OF THE CAPE PENINSULA. 
This plant is a handsome one, and much less common than the 
preceding. 
4, Pterygodium cruciferum, Sonder, in Linnaa, vol. xix. (1847), 
p. 109.—Six to nine inches high; stem leafy, somewhat bent; leaves 
usually 2, oblong-lanceolate, acute, nerved, sometimes twisted, erect 
or spreading, the lower 3-4 in. long, the upper smaller ; raceme some- 
what laxly 2-6 flowered, the hood of the flower about 8 lines long and 
broad, bracts broadly lanceolate, nearly as long as the flower; odd 
sepal lanceolate, acute, incurved above, concave at base; side sepals 
ovate-acuminate, concave, wide-spreading; petals nearly orbicular, 
very concave, and reflexed on part of the margin; limb of the lip 
linear, about 2 lines long, the appendage cruciform, erect, arms 
obtuse, ascending, apex channelled, reaching to the top of the hood; 
arms of the rostellum ascending or nearly horizontal; stigmas 2, 
distant ; ovary obovate. 
Has. Amongst burnt shrubs on the slopes above Van Kamp’s Bay, at about 
300 ft., fl. Sept. (1884). Bolus, 4964; Herb. Norm. Austr.-Afr., 316.—Extends to 
Swellendam and Uitenhage. 
Flowers sulphur-yellow, not quite so large as those of P. acuti- 
folium, which this species resembles in habit. Hasily distinguished by 
the large cruciform appendage to the lip. I have only met with 
it once as above, where it grew in considerable quantity. I was 
indebted for the find to my friend Dr. Marloth, who first detected it, 
and with whom I afterwards visited the spot where it grew. In 
Burmann’s herbarium, now in the De Lessertian herbarium, belonging 
to the City of Geneva, I had the pleasure of seeing there (in August, 
1888) a sheet, of excellent specimens of this plant, marked ‘ collect. 
8 Octobr. 1695.”" There was no collector’s name, but, as will be seen by 
a note in the Appendix, it was almost certainly either Oldenland or 
Hartog, and also almost certainly was gathered on the Cape Peninsula. 
These are probably the oldest herbarium specimens of Cape plants in 
existence. They are still more interesting as showing how long, in spite 
of the labours of numerous collectors, a species may remain ungathered, 
as in the case of this plant, which no one is known to have seen on the 
Peninsula between the year above-named, and that of its re-discovery 
by Dr. Marloth,—a period of 189 years! 
PuatEe 22.—Fig. 18, flower, front view, x 2 diameters; 19, column with lip, side 
view, X 3; 20, column, with lower part of the appendage to the lip, back view, 
mag.; 21, one of the pollinia, mag. In the foregoing, a indicates the anther; g, the 
gland of one of the pollinia; s, one of the stigmas. 
5. Pterygodium caffrum, Swartz, in Kongl. Vetensk. Acad. Handl., 
vol. xxi. (1800), p. 218.—Five to ten inches high ; stem leafy, nearly 
straight ; leaves 8-4, the lowest oblong or ovate, acute or obtuse,
