SATYRIUM. 129 
high; leaves ovate, acute, cordate and sheathing at base, the margin 
wavy and reflexed, the lowest leaf patent 14 in. long, cauline 5 or 6, 
ascending, smaller, and gradually passing into bracts; spike cylindrical, 
densely many-flowered, usually about half the length of the scape; bracts 
leaf-like, ovate, acuminate, ascending, the lower ones always longer, the 
upper sometimes shorter than the flowers; side sepals broadly elliptical, 
very blunt, subfalcate, about 2 lines long; the odd sepal and petals 
ovate-oblong, blunt, revolute, a little smaller; lip galeate, oblong, 
mouth 24 lines wide and wider than long, depressed in the centre and 
the long blunt point deflexed in front, forming two circular entrances 
to the flower, with two short blunt sacs at base; column short, bent 
back and then upwards, sharply bilobed at the apex; anther slightly 
ascending, its apex turned to the front of the flower, the glands 
posterior and distant; rostellum triangular and very short, pushed by 
the anther upward so as to cover and conceal the stigma, with 2 large 
tubercles at base; stigmatiferous lobe of the column semi-orbicular, 
small; ovary elliptical, muricate on the ribs, about 14 lines long. 
Var. «. THunpercianum.—All the bracts longer than the flowers ; 
the deflexed point of the galea short, reaching less than half-way down 
to the base. 
Var. 8. oceLLatum.— Upper bracts shorter than the flowers; 
deflexed point of the galea very long, reaching nearly to the base, and 
forming two circular entrances to the flower. 
Has. Both varieties on steep gravelly slopes on the mountains of the 
Peninsula, mostly on the eastern sides; also on the lower plateaux, alt. 600—2500 
ft.; fl. Oct.-—Nov. Bolus, 4554; Herb. Norm. Austr.-Afr., 335. 
The colour of the flowers in both varieties is whitish, suffused with 
yellow or greenish tints. The size of the flowers is somewhat variable. 
In the structure of the column this species differs from any other 
known tome. The anther, instead of hanging vertically under the 
rostellum with its glands pointing forward, as is the typical structure 
in the genus, appears as if pushed up against the apex of the column, 
so as to lie nearly horizontal, with the glands turned to the back of the 
flower, and the stigma completely covered and hidden from view. 
The economy of its fertilisation is a puzzle to me, for the appearance 
is as if the process were carefully prevented (just as Darwin observes 
is the case with Masdevallia fenestrata, but ‘‘ which,” he adds, ‘‘ proves 
that we do not know its structure’’), But I have not had the oppor- 
tunity of watching it, and have never seen any insect or trace of insect- 
work on the plant. In appearance it greatly resembles S. Lindleyanum, 
but the deflexion of the point of the galea will generally serve to 
distinguish it, independently of the great difference in the column.
