DISA. 148 
to D. reticulata, but it may be usually known by its fewer and shorter 
leaves, different bracts, looser spike, larger deep-coloured flowers, and 
much larger and higher rostellum. It does not seem to be abundant, 
but patches of ten or a dozen plants may occasionally be found in 
places which have been moist all the winter. 
6. Disa affinis, NV. F. Brown, in Gardeners’ Chron., vol. xxiv. (1885), 
p. 402.—Glabrous, usually decumbent, 1-14 feet high; lowest leaf 
elliptical, subobtuse, many-nerved, sheathing at base, spreading, 4-8 
in. long, 2-24 in. wide, the upper (1-2, rarely 3) gradually smaller, 
acute, mucronate, passing into 4-5 submembranous appressed sheaths ; 
bracts broadly ovate, acuminate, membranous, netted-veined, a little 
shorter than the ovary, and closely enwrapping ovary and spur; spike 
loose, 3-5 in. long; side sepals oblong, subacute, 3-nerved, spreading, 
24-3 lines long; odd sepal with an arched obtuse limb, 5 lines long, 
with a filiform dependent spur 1 in. long, equalling or a little shorter 
than the ovary; petals obliquely ovate, sub-faleate, generally emargi- 
nate, 8-nerved, a little shorter than the odd sepal; lip oblong, very 
obtuse, or narrowed at the apex, about 4 lines long; arms of the 
rostellum turned backward, scarcely exceeding the prominent large 
rounded stigma, and separated from it by a deep excavation. Monadenia 
rufescens, Lindley, in Gen. & Sp. Orch. (1838), p. 356, excluding 
synonyms. M. comosa, Reichb. f. Linnea, vol. xx. (1847), 687. 
Has. In clefts of rocks, and shady places on the eastern mountain-sides of the - 
Peninsula, 1400 to 2500 ft., fl. Sept.—Oct., frequent, Bolus, 4555; Herb. Norm. 
Austr.-Afr., 170.—Extends to Clanwilliam and Swellendam (Burchell, 7321, 7357; 
Zeyher, 3925). 
The leaves are a sap-green, the sepals sulphur-yellow, the petals 
bright golden. One of the most distinct species of this group, and 
readily known by its large broad lower leaves, its lax, often weak 
habit, and the pale colour of the whole plant, both when living and in 
the dried state. The column is also well-marked. The sepals are 
thin, the petals thicker but scarcely fleshy, as in most of this section. 
It loves the steep sides of rocky hills or crags which are turned away 
from the sun, and often nestles amongst high grass or under shrubs. 
7. Disa reticulata, Bolus, in Journ. Linn, Soc., vol. xxii. (1884), 
p. 73.—Hrect, or slightly decumbent, glabrous, 4-12 in. high; scape 
leafy, usually slender at the base; lower leaves linear-lanceolate, 
acuminate, sheathing at base, erect, the upper gradually smaller, 
ovate-lanceolate, reaching a little below the base of the spike; spike 
rather lax, about half as long as the plant ; bracts broadly ovate, with 
a long twisted point, membranous, netted-veined, enwrapping spur and 
ovary, a little longer than the flower; side sepals oblong, obtuse,
