112 ORCHIDS OF THE CAPE PENINSULA. 
Has. Grassy places and amongst bushes at the foot of the hills near the sea- 
shore, Sea Point; also on Wynberg Hill, &c.; fl. Sept. ; tolerably common, especially 
in the first-named locality ; Herb. Norm. Austr.-Afr. 154.—It also extends along the 
coast eastward as far as Grahamstown, and possibly further. 
The petals and labellum vary from creamy-white, suffused with 
violet, to light purple. The flowers vary in size, which led Lindley to 
distinguish two species, which, however, cannot otherwise be separated. 
It is one of the prettiest as well as one of the most curious of our 
smaller Orchids, and the fancied resemblance of the lip-segments to 
the legs of a spider has led to its being called the ‘‘ Spider Orchid.” 
It was introduced into England by Masson in 1787. 
2. Bartholina Ethele, Bolus, in Journ. Linn. Soc., vol. xx. (1884), 
p. 472.—All parts, except the flower, clothed with spreading hairs ; 
scape erect, slender, 6-10 in. high, 1- or very rarely 2-flowered; leaf flat, 
withering before the flower opens, 10-15 lines in diam. ; sepals linear- 
lanceolate, acute, glabrous, reflexed, 6-7 lines long; petals oblong- 
falcate, obtuse, a little longer than the sepals; lip nearly orbicular in 
outline, 3-lobed, the lobes cut into 17-28 linear upturned segments, 
which are dilated at the apex into flattened cushion-like processes, the 
whole, including the spur at base, 13-13 in. long; ovary bent, about 
10 lines long. 
Has. Under shrubs at the foot of a dry hill overlooking the sea between Kalk 
Bay and Fish Hoek, altitude 150 ft.; fl. Dec.; Bolus 4859! Herb. Norm. Austr.-Afr. 
500; also in a valley on Muizenberg Mt. in sandy places, at about 900—1000 ft. 
elevation, growing with Eulophia ustulata. 
This species seems to be comparatively rare. I have twice gathered 
it at the same spot near Kalk Bay, but it needs to be carefully searched 
for. It had previously been collected by the Rev. W. Rodgers and by 
Admiral Sir F. Grey, who sent it to Kew, but gave no locality more 
exact than the vague term, ‘“‘Cape.” The colour of the petals is a 
pale blue; the lip pale blue above, brownish beneath. The species is 
readily distinguished by the characters given. 
Puate 3.—Fig. 1, lip x 14 diameters; 2, column, with side petals, anterior view 
x3; 3, flower, side view, natural size; 4, the flower, after removal of the petals and 
lip, to show the position of the stigma, magnified; 5, tip of one of the segments of 
the labellum, magnified ; 6, pollinium, magnified. Note.—The scape has been drawn 
too thick.
