WAILESIA PICTA Lindl. 1. c. et Paxl. Fl. G. XVL 321: 



Epiphyle. Habit of Vanda, Angrecum. Caulescent. Leaves long , in two oppo- 

 sile rows, coriaceous, chaneiled, threeribbed, terniioating in an acute nearly obiique 

 point. Peduncle rising from the side of the stem , erect, nearly a foot long, deep 

 purple, bearing from 9—12 Uowers. each about an inch and a half in diameter, exter- 

 nally brightly spotted wilh crimson on a pale yellow ground ; inside the spots only 

 just show ihrougli. Sepals and pelals spreading, narrowly oblong, blunt, very nearly 

 alike in size, form and lexture, except thal the two lateral sepals are slighlly oblique 

 at the base. Labellum oblong , saddle-shaped , blunt, and coaisely wooliy at the 

 upper end , shaggy along the middle ; at the sides it is smooth , and streaked with 

 crimson ; at the base it is Uatiened and dovpny , united by the edges to the column, 

 so as to form a smaii sac , but desiitute of any appendage witbin the sac except a 

 smail rounded callosity; above the sac on either side , it has an obtuse linear smooth 

 tooth. Coiumn short , stiff, truncated, deep yellow at the end , rounded at back and 

 plain in front, where it is moreover hollowed out near the base and closely covered 

 with a soft felt. Stigma small transversal oval space near the summit of ihe co- 

 lumn. Anther whitish, placed obliquely in rear of tlie stigma with an ovate point 

 and twocelled. PoIIenmasses two, globular , partially two-lobed, each attached to a 

 long, narrow diverging caudicle , holding fast to a common ovate gland.

Galeandra from galea, a casque, and aVYjp, an anther; in allusion to the crested 

 aniber. At Hrst sight this would seem to be a hybrid name , being constructed of 

 iwo words belonging lo diflerent languages; bul as galea itself is from the Greek 

 ycLki], I hope critics will consider ihe name allowable. 



Sertum Orchid. 37 : Perianlhium patens , petalis sepalisque subaequalibus ascen- 

 deniibus. Labellum infundibuliforme indivisum vel obsolete trilobum , calcari intus 

 lamellis (4) auctum. Columna erecta membranaceo-alala , ciinandrio declivi. Pollinia 

 2, postice excavaia, caudicula brevi, glandulae brevi divcrgenti bilobae adnata. Herbae 

 terrestres et epiphylae. caulibus foliatis , racemis terminalibus. — I had suggested 

 G. Baueri mighl be combined with ihe Eulophia gracilis B. Reg. and a third Sierra 

 Leone plant hy the funnel shaped undivided lip , the crested anther, peculiar form 

 of ihe gland, to which poilenmasses are aitached. These characters are essential 

 to Galeandra, but also in parl important and it is requisite for them 'lo be combined 

 with other peculiarities in order to constitute a really good genus. Of the cha- 

 racters to be rejecled ihe crested anlher is principal, of those to be added , the 

 presence of 4 pnrallel plates npon the lip and a terminal inOorescence. Euloph. gra- 

 cilis will in that case be excluded from Galeandra, and so perhaps will G. extinctoria, 

 both which rcquirc fiirther examinaiion in ordor to deicrmine whethcr or not ihoy are 

 to be slaiioned deflnitively in the genus Eulophia. Zygopetalum and some oihers 

 nearly allied to Galeandra, involve some verv difflcult inquiries for which sufficienl 

 materials have hardly been as yet accumulaied.
