Selago continued.

 lin. to 3in. long, or the panicle shortened and loosely few- 

 flowered. I. clustered, whitish, glabrous, elliptic-lanceolate or 

 the lower ones ovate, three to six lines long. Stem branched.

S. rotundifolia (round-leaved), fl. purple ; corolla tube filiform, 

 three or four times longer than the calyx ; spikelets terminal, 



straight, pedunculate, scarcely lin. long. I. obovate-elliptic, 

 glabrous, entire, clustered-fasciculate. Stem straight, terete.

corymbs ; corolla tube filiform, elongated ; bracts linear-subulate. 



I. obovate-elliptic, acute, serrated, decurrent, often glabrous. 



Stems straight, leafy. A. 1ft. 1774. SYN. S. fasciculata (B. B. 



184 ; L. B. C. 1423).

SELANDB.IA CEB.ASI. A name formerly given in 

 England to the Sawfly now known as Eriocampa limacina, 

 the parent of the dreaded Slugworm, frequently so destruc- 

 tive to most kinds of fruit-trees, e.g., Cherry, Pear, and 

 many others, as well as to several forest-trees, e.g., Oak 

 and Birch. See Slug-worms. 



SELATITTM. A synonym of Gentiana. 



SELENIA (probably from selene, the moon ; con- 

 nection not obvious). OED. Cruciferce. A small genus 

 (two species) of small, hardy, annual herbs, natives of 

 Texas and Arkansas. Flowers yellowish, in terminal, 

 leafy racemes ; sepals spreading, coloured, sub-equal ; 

 petals erect. Leaves pinnatisect. 8. aurea, whether for 

 the colour or odour of its flowers, or for the consider- 

 able time it remains in blossom, is well worthy of cul- 

 tivation. It requires similar treatment to other hardy 

 annuals. 



S. aurea (golden).* fl. erect, the lower ones solitary in the upper 

 axils, the upper ones collected into a sub-corymbose raceme ; 

 sepals greenish-yellow ; petals golden-yellow, twice as long as the 

 sepals, obovate-spathulate. June. I. lin. to 2in. long, iin. to iin. 

 broad, linear-oblong, pinnatifid ; segments about five to seven 

 pairs. A. Sin. 1881. (B. M. 6607.) 



SEIiENIFEDIUM (from selenis, a little crescent, 

 and pedion or podion, a slipper ; in allusion to the 

 crescentic, slipper-shaped labellum). South American 

 Lady's Slipper. Including Uropedium. OED. Orchidece. 

 A genus comprising about a dozen species of stove, 

 terrestrial Orchids, differing from Cypripedium in having 

 a three-celled and three-furrowed or three-lobed ovary; 

 they inhabit the mountainous parts of South America, 

 Flowers showy or rarely mediocre, pedicellate; sepals 

 spreading; petals free; lip sessile, spreading, inflated 

 like a slipper; peduncles many-flowered. Stem erect, 

 leafy. Eegarding 8. SchUmii, Mr. B. S. Williams re- 

 marks (in the "Orchid Grower's Manual"): "This is a 

 difficult plant to cultivate. -The imported plants appear 

 as if they had been growing beside streams of water 

 which are subjected to being flooded, for the leaves 

 are frequently coated to a great extent with deposited 

 mud; and it would, therefore, appear that our difficul- 

 ties with this plant have arisen chiefly from an insuffi- 

 cient supply of water. We pot in peat, adding a little 

 turfy loam and sand, with good drainage, and take 

 care that water does not lodge in the heart of the 

 plant. It is best grown at the cool end of the Cattieya 

 house." For general culture, see Cypripedium (under 

 which the species were formerly included). 

 S. AinswortMi (Ainsworth's).* fl., upper sepal whitish or yel- 

 lowish-green, bordered with pale purple, the lower one very wide, 

 ventricose ; petals rather broad, purple, with a green mid-vein 

 and a pallid area near the base ; side lacinije of lip reflexed, 

 pale sulphur-yellow, copiously spotted inside at base ; staminode 

 sulphur-colour, with a dark purple, hairy border outside. 1878. 

 A hybrid between S. Sedeni and S. Roezlii. 

 8 albo-purpureum (white-and-purple). /. much larger than in 

 'S Sedeni; dorsal sepal having a pinkish tinge on the margin, 

 elon-nted-ovate ; petals pinkish, 5in. to 6m. long, twisted, 



Selenipedium continued. 



hanging down beyond the lip ; pouch of the lip dull crimson- 

 red, the inflected edges at its base ivory-white, bordered with 



Rink, and nearly covered by rosy spots. 1. long, green, linear- 

 mite. A handsome garden hybrid between S. Dominianum 

 and S. Schlimii. SYN. Cypripedium albo-purpureum (Gn. xxL 332X 



S. calurum (beautiful-tailed).* fl. large and showy, freely pro- 

 duced ; dorsal sepal pale green, longitudinally ribbed with 

 purple ; petals pale green, edged with rose-red near the base, 

 wholly bright rose-red at apex, 2iin. long, narrower and more 

 twisted than in S. Sedeni ; lip of a deep wine-crimson outside, 

 very handsome. I. elongated, channelled, acute, green, in a 

 thick tuft. Stems tall, branched, brownish-red. A handsome, 

 free-flowering hybrid between S. lonqifolium and S. Sedeni.

S. cardinale (cardinal), fl., dorsal sepal blush-white, faintly 

 striped with green ; petals blush-white, with a patch of crimson- 

 purple hairs towards the base ; lip similar to that of S. Schlimii, 

 but about lin. in diameter. December. A beautiful hybrid 

 between S. Sedeni and S. Schlimii albijtorum. 



S. cariclnum (Carex-like).* fl. pale green, the sepals and petals 

 having a white margin, and the ends being blotched with brown ; 

 petals narrow, defiexed and twisted ; lip black-dotted on the 

 inner margin, oblong ; staminode bordered with black hairs ;

 narrow, channelled. A. 1ft. or more. Peru. Plant having a 

 Sedge-like appearance. SYNS. S. Pearcei (F. d. S. 1648), Cy- 

 pripedium caricinum (B. M. 54>6). 



S. caudatum (tailed).* fl., sepals and petals yellowish, marked 

 with brown ; petals taU-likef often reaching 24ft. in length, 

 more deeply coloured towards the base ; lip reddish-brown, the 

 basal portion yellow, spotted with reddish-brown ; scapes 1ft. to 

 lift high. April and May. J. ensiform, distichous, light green.
