_Selaginella—continued. 
long, not cuspidate. spikes square. 1865. Greenhouse. Sup- 
posed to be a garden hybrid between S. wneinata and 
S. tnequalifolia. 
S. oregana (Oregon).* stems pendent, flaccid, 1ft. to 6ft. long, 
pinnate, much-branched. /. uniform, linear-lanceolate, convex 
and grooved at back, sparsely denticulate, scarcely jyin. long, 
acute, but not bristle-tipped. spikes square, very slender, 
resembling the sterile branchlets. Oregon. Greenhouse. A 
beautiful species. 
S. perelegans (very elegant). The correct name of this plant 
is S. inwqualifolia perelegans (under which it is described on 
bi 411, Vol. IIT.). See Fig. 671, for which we are indebted to 
Messrs. W. and J. Birkenhead. 
S. Pervillei (Perville’s). A synonym of S. Vogelii. 
S. Pitcheriana (Pitcher’s). A form of S. erythropus. 
S. radiata (radiate).* stems slender, sub-erect, 6in. to 12in. long, 
acutely angled down the face, closely pinnate, sometimes 
stoloniferous at base; branches copiously compound. J. of the 
lower plane contiguous on the branchlets, spaced on the main 
stem, erecto-patent, ovate, acute, jin. to jin. long, much 
Selaginella—continued. 
S. usta (burnt). stems Sin. to 12in. long, erect, simple at base, 
compound above; branches erecto-patent, the upper ones 
copiously compound. JU. of the lower plane crowded, erecto- 
patent, bright green, rigid, dilated, serrulated, imbricated on 
the upper side at base; leaves of the upper plane one-third as 
long, acute, much imbricated. spikes square, tin. to sin. lone. 
New Caledonia. Stove. : ‘ 
S. Victoriz (Victoria's). Of this lovely species, intermediate 
between S. Wallichit and S. caniculata, a portion of a stem is 
shown at Fig. 673 (for which we are indebted to Mr. Bull). 
S. viridangula (green-angled).* stems sub-erect, sarmentose, 
3ft. to 4ft. long; pinne deltoid, 1ft. long, erecto-patent ; 
pinnules with simple upper and compound lower erecto-patent 
tertiary divisions; ultimate segments usually in. to lin. long, 
bright green at base. J. of the lower plane contiguous or 
nearly so on the branchlets, lanceolate-falcate, acute, sin. to 
tin. long (jin. long and much spaced on the pinne), bright 
green, dilated; leaves of the upper plane very small, distinctly 
cuspidate. spikes square, lin: to 2in. long; bracts strongly 
keeled. Mountains of Fiji, 1884. Stove. z 
S. Warscewiczii (Warscewicz’s). A synonym of S. radiata.

Fic. 673. PORTION OF STEM OF SELAGINELLA VICTORIA. 
imbricated on the upper side at base, strongly ciliated; leaves 
of the upper plane half as long, cuspidate. spikes square, 4in. 
to lin. long. Tropical America (up to 9000ft.). Stove or green- 
house. SYN. S. Warscewiczii. 
S. radicata (rooting). A synonym of S. plumosa. 
S. spinulosa (slightly spiny). A synonym of S. spinosa. 
5. eee (narrow-leaved). stems pale straw-coloured, 
sub-erect, 6in. to 12in. long, rooting from the lower half, 
copiously pinnate ; lower branches copiously compound. J. of 
the lower plane anette oblong-lanceolate, j;in. to Jin. long, 
serrulated and imbricated on the upper side; leaves of the 
upper plane one-third to half as long, cuspidate. spikes 
resupinate, short. Mexico. Stove. S. albospica is a form of 
this species, 
S. tassellata (tasselled).* stems erect ; branches and branchlets 
flat, closely pinnate, the tips furnished with fertile, quad- 
rangular spikes about l4in. long, giving the plant a tasselled 
appearance, Brazil, 1887. Stove. See Fig. bra, for which we 
are indebted to Mr. Wm. Bull. 
S. uliginosa (swamp-loving). The correct name of Lycopodium 
uliginosum. 
Vol. V. 
SELAGO. Several species formerly included here are 
now classed under Microdon (which see). 8. myrtifolia 
is the correct name of S. Gillii. 
SELENIPEDIUM. Under Cypripedium the various 
hybrids of Selenipediwm will be found, with their recorded 
parentage. So far as these are concerned, they are amongst 
the most difficult Orchids to grow. Many of the most 
familiar, such as S. caudatum (Fig. 674), S. caricinum, 
S. Lindleyanum, and 8. Schlimii, are but seldom met with 
in perfection. This is the more pronounced and inex- 
plicable from the fact that, almost without exception, the 
hybrids that have been derived from the intercrossing of 
the species are about the most tractable Orchids in culti- 
yation. ‘There is certainly no freer and more vigorous class 
of Orchids under almost any conditions than the majority 
of the Selenipedium hybrids. Their requirements are best 
met by growing them with the intermediate section of Cypri- 
pediums. They require a liberal supply of moisture, both at 
the roots and in the atmosphere, at all seasons of the year.
