66 CXLVIII. ORCHIDE^E. (J. D, Hooker.) [Saccoldbivm. 



but spur not so long or so much incurved, gland of the pollinia smaller. Capsule 

 f-1 in., narrowly fusiform, shortly pedicelled. 



DOUBTFUL AND IMPERFECTLY KNOWN SPECIES. 



S. CLAVATUM, Lindl. Gen. <$ Sp. Orchid. 223. (Epidendrum clavatum, Retz 

 Obs. vi. 50. Limodorum clavatum, Willd. Sp. PL iv. 126; caulescent, pendulous, 

 leaves linear clavate 2-toothed, spikes leaf-opposed, lip inflated bearded. East 

 Indies, on trees. It is impossible to say what this is; it had better be suppressed. 



S. DASYPOGON, Lindl. Gen. ty Sp. Orchid. 222. (Aerides dasypogon, Smith in 

 Rees Cyclop. Suppl. Epidendrum umbellatum, Ham. mss.) ; stemless, leaves 

 ovate-oblong acute obliquely 2-toothed, corymbs subumbellate, sepals and petals in- 

 curved linear-oblong green without blood-red within, lip white dotted with blood- 

 red, limb dilated subcordate toothed. Nepal, Hamilton. (Probably S. calceolare). 



S. PECHE"I, Eeichb. f. in Gard. Chron. 1887, i. 447 ; leaves very broad 7 by 2 in. 

 ligulate obtusely 2-lobed, raceme few-fld., flowers as in Sect. Calceolaria, as largre as 

 S. bellinum, sepals and petals cuneately oblong ochreous spotted with red, lip a 

 cupular spur, side lobes retuse and angular over the transversely triangular midlobe, 

 blade white and yellow base of the spur spotted with red. Moulmein, Peche. (I 

 have seen only imperfect cultivated specimens in Herb. Kew. It appears to be a 

 very distinct large-leaved species of Sect. Calceolaria, J. D. H.) 



ACAMPE GRIFFITHII, Eeichb. f. in Flora, 1872, 277 ; near A. dentata, spur 

 cylindric hairy within, midlobe of lip triangular angled on each side at the base pro- 

 truding, two intermarginal lamellae (" lineatis apice lobosis "), disk warted all over.- 

 The rest as in A. dentata, Lindl. Bhotan, Griffith. 



ACAMPE INTERMEDIA, Reichb. f. in Otto. Sf Dietr. Algemein. Gartenzeit. 1856, 

 217; near A. mulliftora, Lindl.; flowers like those of A. papillosa, Lindl., leaves 

 shorter lovate lip equally 2-lobed, raceme short corymbose, lip (" labello aplectro"), 

 canal between the lateral lobes hairy, midlobe oval acute tubercled. 



65. SARCANTHUS, Lindl. 



Characters oiSaccolabium, but spur with a dorsal usually 2-lobed callus 

 or an erect plate within, inserted under the column, and with the cavity 

 more or less divided by a vertical septum. Species about 20, Tropical 

 Asiatic. 



But for the inconvenience attending the substitution of a new generic name 

 for the numerous species of this genus, I should unhesitatingly unite it to 

 Cleisostoma, and both to Saccolabium. The only character whereby its species can be 

 distinguished is the more or less septate cavity of the spur, often a very obscure one, 

 and almost inappreciable when the septum is reduced to a mere ridge. 



* Leaves elongate, filiform. 



1. S. filiformis, Lindl. in Bot. Reg. 1842, Misc. 61 ; leaves 8-10 in., 

 racemes long lax-fld., sepals oblong obtuse, petals smaller and narrower, 

 lip broadly conically, saccate base 2-lobed, side lobes acute incurved, mid- 

 lobe short broad toothed on each side at the base. Sot. Mag. t. 4639 ; 

 Jard. Fleur. 266. 



SIKKIM HIMALAYA, Griffith's Collector. KHASIA HILLS, Lobb. TENASSERIM, 

 Parish. 



Stem pendulous, as thick as a duck's quill, terete. Leaves distant, i in. diam., 

 obtuse. Racemes 6-10 in., curved : bracts minute, ovate ; pedicels very short ; 

 flowers ^ in. diam. ; sepals and petals dark purple, margins and midrib green ; lip 

 fleshy, white, base broad yellow, midlobe white, sac with a narrow lamina from 

 the base of the midlobe downwards, and a very large-lobed hispid callus below the
