159. ORCHID ACE. E. [21. Luisia. 



purple flowers •25-' 3" long with pink petals and a disagreeable smell 

 of bugs. 



Sent bv Rev. Cardon from Sarguja to the Botanic Gardens, Calcutta, where it 

 flowered Feb. ! Also fls. March-May. Leafless when in flower. 



Leaves 2. Inflorescence dense, bracts minute acute. Dorsal sepal sliortest 

 triangular-ovate obtuse 3-nerved, lateral falcately oblong obtuse. Petals ovate- 

 oblong 1-nerved. Lip stipitate broad convex obtuse. Spurs on column slender. 



20. CIRRHOPETALUM, Lindl. 



Habit of Bulbophyllum mostly Avith small 1 -leaved pseudobulbs 

 on a creeping rhizome. Flowers usually small, umbellate, rarely 

 umbels reduced to 1-2 flowers. Median sepal free, lateral sepals much 

 longer twisted on their long axis and with their outer margins more or 

 less conniving. Petals much shorter, often fimbriate or appendaged. 

 Lip linguiform, very small, stipitate. The rest as in Bulbophyllum. 



1. C. ornatissimum, Reichb. 



A remarkable and curious little plant with ovoid pseudobulbs 

 bearing 1 (rarely 2) oblong leaf 3-4-5" long and purple flowers, the 

 umbels reduced to one or two flowers. 



Jashpur, Cardon ! Fl. Oct. 



I have only seen the one specimen. It has 2 flowers, and the tips of the sepals 

 are broken off in one and in the other are 2" 3" only, erect. In a drawing of C. 

 ornatissimum at the H.B.C. the sepals are 3-4" long (as described by Pruin for our 

 plant), but on this drawing Rolfe has remarked C. Mannii not C. ornatissimum. 

 It is also much smaller than the C. ornatissimum from Sikkim which has sepals 

 filiform up to 4-5" (= C. appendiculatum. Rolfe 'i). The hnear lip is -3" long. 

 The F.B.I, describes C. crnatissimum as with lateral sepals 2-4" linear-lanceolate 

 with fihform tips 6-nerved much longer than the cymbiform acuminate .5-nerved 

 dorsal, petals subulate-lanceolate falcate 3-nerved and dorsal tipped with a brush 

 of slender red palese, lip strigose, columnar, arms large decurved. 



21. LUISIA, Gaud. 

 Tufted epiphytes without pseudobulbs, with terete rigid sheathed 

 stem and elongate terete obtuse leaves. Flowers small drooping on 

 a short or very stout erect axillary rhachis, bracts persistent, very 

 short thick and imbricating. Sepals subequal or the decurved dorsal 

 smaller. Petals narrower often longer. Lip sessile on the base of 

 the column, base flat, concave or saccate. Column very short, 

 truncate ; anther 2 -celled, pollinia 2, sub-globose, seated on a replicate 

 short strap. Capsule narrow erect. 



Leaves 4-5". Flowers • 4" long 1. trichorhiza. 



Leaves 1-2". Flowers -15" long 2. inconspiciia. 



1. L. trichorhiza, Blume. 



Stems rather stout with thick truncate sheaths. Leaves stout 

 terete 4-6" long. Flowers • 4" long. Sepals and petals pale yellowish 

 green with faint purple lines. Petals about as long as the lateral 

 sepals. Lip rather longer than the sepals, dark purple with faint 

 green lines, obovate-oblong flat grooved constricted between the 

 broadly ovate or subcordate epichile and the quadrate hypochile. 

 Column purple. Capsule -6" strongly ridged narrow with attenuate
