Satyrium rhodanthum, Schlechter, iu Engl. Bot. Jahrb. xl, 92. “ Erectum 
strictum, 25 — 40 cm. altum ; foliis basilaribus 2, erecto-patentibus, post 
anthesin e gemma distincta ad basin caulis evolutis; caule tereti glabro,

spica oblonga vel ovata, cylindracea, dense 10 — 25-flora; bracteis lanceolatis 
acutis, mox deflexis, inferioribus flores superantibus, superioribus sensim 
decrescentibus ; floribus pulchre roseis, illis S. Woodii, Schltr. similibus et 
aequimagnis; sepalis petalisque liberis decurvulis glabris, ca. 1-3 cm. longis; 
sepalo intermedio oblongo-ligulato obtuso, lateralibus paulo latioribus ; petalis 
et sepalis lateralibus valde similibus; labello galeato, limbo inflato, dorso 
medio longitudinaliter carinato, apice libero erecto quadrato obtuso, intus 
microscopice papilloso, margine minute serrulato, calcaribus filiformibus 
deflexis, ovarium duplo superantibus; columna gracili incurva, rostello 
quadrato, apice trilobulato, lobulis lateralibus minutis dentiformibus acutis, 
intermedio lanceolato-elliptico obtuso majore; lobo stigmatifero cuneato- 
quadrato, leviter bilobo, rosteflum longitudine aequante.” [Ex Schlechter, 
l.c. supra.] 
South-Eastern Region: Natal; Alexandra County, in damp meadows along 
the Umtwalumi at Fairfield, alt. ca. 700 met., fl. Oct. 1905, H. Rudatis, 128. 
Erect straight, 25 — 40 cm. high ; basal leaves 2, erect-spreading, developed 
after the flowering-period from a distinct bud at the base of the stem; stem 
terete glabrous, entirely covered by several, acute or acuminate, closely 
embracing sheaths; spike oblong or ovate, cylindrical, densely 10 — 25-fl. ; 
bracts lanceolate acute, soon deflexed, the lower ones longer than the flowers, 
the upper ones gradually smaller; flowers a beautiful rose colour, similar to 
those of S. Woodii, Schltr., and as large: sepals and petals free, very similar, 
decurved glabrous, about 1*3 cm. long; intermediate sepal oblong-ligulate 
obtuse, a little broader than the lateral ones; lip hooded, the limb inflated, 
dorsally longitudinally keeled in the middle, the apex free erect quadrate 
obtuse, microscopically papillose within, margin minutely serrulate, spurs 
filiform deflexed, twice as long as the ovary; column slender incurved, the 
rostellum square, trilobulate at the apex, the lateral lobules minute tooth- 
like acute, the intermediate larger lanceolate-elliptic obtuse; stigmatiferous 
lobe cuneate-quadrate, slightly 2-lobed, as long as the rostellum. 
The drawing was made from living specimens collected at Dumisa in Natal 
by H. Rudatis, Nov. 13, 1911 (Bolus Herbarium, No. 18375). Dr Schlechter 
remarks (l.c. supra): ‘‘This beautiful species is related to S. Woodii, Schltr., 
but is distinguished by the longer spurs and by the shape of the stigmatiferous 
lobe of the column. The flowers are carmine red.” 
Disa tripetaloides, N. E. Brown, in Gard. Chron. (1889) v, 360. Sat

subradicalia 7—9, adscendentia vel fere erecta, oblonga vel linearia, rarius
