Has. Sandy places on the Cape Flats, ed. near Rondebosch, alt. 60 ft. ; fl. Oct. 
(rare), Bolus.—Extends to Malmesbury (Zeyher, 3927); Paarl (Herb. Norm.-Austr. 
Afr., 172) ; and Hex River Mountains (1600 ft., W. Tyson, 642). 
The sepals are pure white, the petals and lip rich golden yellow 
with tawny spots. The flowers are striking and pretty, larger than 
those of any other species of this group, and very distinct in their 
appearance. I have only found it once within our limits, but it is 
very frequently met with near Paarl and Malmesbury. 
29. Disa torta, Swartz, K. Vet. Acad. Handl, 21 (1800) 211.—Six 
to eight inches high; scape much bent, 1-4 flowered; peduncles 
lengthening, the older, including the ovary, 8-9 lines long; side 
sepals linear, much acuminate, with incurved margins, a tooth-like 
lobe on the upper margin near the base, 8-9 lines long; the odd sepal 
with a similar but shorter and recurved limb, produced at base into a 
compressed, horizontal or ascending spur, retuse at the apex and 
shorter than the limb; petals adnate to the column at base, linear- 
faleate above, the points turned backward and more or less deeply 
notched or cleft, knee-bent below, the lower portion widened with 
an erect ear-like lobe in front; lip somewhat fleshy, from a broad base 
sharply bent downward, the middle part ovate, margins incurved, erose, 
point filiform 2—4 lines long. Orchis biflora, Linneeus, Spec. Plant. ed. 
2 (1763), 1880. Satyriwm tortum, Thunberg, Prodr. Pl. Cap. (1794) 5.

Has. ‘On the summit of the mountain near Constantia, 2000 ft.; fl. Sept.,” 
Krauss, 1326.—Extends to Stellenbosch, Wellington, Tulbagh, Caledon. 
Colour of the flowers varying from pale lilac to rose-red, with 
darker, sometimes numerous, minute greenish spots or papille on the 
surface of the lip, and larger pale purple spots on the petals. If Iam 
right in my identifications this is a very variable plant, and it is 
probable from the description that S. longipetalum, Lindley, ib., is one 
of its numerous forms. Nevertheless, all are very distinct from any 
other species, and it may readily be known by its narrow arching 
sepals, longer than those of any other, and the long straight point of 
its lip. I have never seen it on the Peninsula, and insert it here on 
the authority of Dr. Krauss (Beitrage zur Flora des Cap und Natal- 
landes, 1846, p. 157). My description is based upon living specimens 
collected by Miss Farnham near Stellenbosch, and numbered 5922 in 
my herbarium,
