159. OBCHIDACE^. [16. Eulophia. 



2. E. nuda, Lindl. 



A ground orchid about 12-20" high, the scape arising from the base 

 of the ultimate joint of a chain of wrinkled somewhat flattened tubers, 

 one of which is formed annually. Flowers white or red, greenish or 

 crimson, sub-globose, about 1-25-1 -5" from spur to tip of dorsal 

 sepal. Sepals '8-1", linear-oblong or oblong, crimson green or 

 yellowish, -2" wide, obtuse, lateral somewhat incurved erect, base 

 forming a mentum with the forked foot of the column. Petals erect, 

 •7- -8" by -3" wide in middle hooded over the column, somewhat 

 oblique, obtuse, many-nerved. Lip oblong, not constricted, with 

 erect short rounded side-lobes, midlobe nearlj' -5" spreading with 

 wavy crenulate ridges at the sides, yellowish with pink veins or red- 

 purple or pure white; spur -15-- 25" long. 



Frequent in Sal forests, rarer in grass-lands. Singbhiim ! Ranclii ! Palamau I 

 Mayurbhanj, Hooper ('? see below) ! Fl. May-June; leaves appear after flowering 

 in June. 



Annual tuber about 2" long. Leaves plicate 10-15" usually appearing after 

 the flowers but in Hooper's specimen tvith the flowers, and in this also the raceme 

 is close instead of lax as is usually the case. Bracts subulate acuminate, -5". 

 Ovary with very short pedicel 1" or lower longer. The floor or throat of the lip 

 is ner^-ed, not crenulate nor tubercled, the crenulations only occiuring on each 

 side, or in some cases 2 calli in the throat and nerves tubercled. Pollinia 2 large 

 waxy sessile on a very broad appendage (caudicle). 



3. E. campestris, Wall. 



A slender orchid with flowering stem 8-12" high, lateral from the 

 last of a chain of erect ovoid tubers which are connected at their 

 base. Flowers mod. -sized in lax racemes, sometimes secund or 

 nodding on slender pedicels. Sepals •4-- 5" linear-oblanceolate or 

 linear-oblong, greenish outside, brownish inside, 5-nerved. Petals 

 elliptic or broadly oblong obtuse, as or nearly as long as the sepals, 

 •2-- 22" broad, broader {F.B.I, says narrower!) than the sepals, 

 greenish or yellowish with red or brown clouds, about 5-nerved. Lip 

 •35-' 45" long oblong, side-lobes erect or upcurved adnate to column, 

 short, beautifully veined with red, midlobe slightly expanded and 

 retuse at the end, yellow, palate with 2 crenulate lamellse or ridges 

 starting from the base of the column and tapering off to the end of 

 the midlobe, the expanded part of which then has a crest of 5 fleshy 

 papillose ridges. Spur hardly any and obtuse (in my notes and 

 specimens ; acute F. B.I.). Foot of column or scarcely any. Pollinia 

 2, notched and perforated near the base, strap short and broad. 



Not imcommon in open forest and burnt savannahs. Singbhura ! Ranchi ! 

 Palamau, at Neterhat, 3000 ft. ! Fl. April-May. 



4. E. explanata, Lindl. 



A shorter stouter plant than E. camjyestris with scape 4-8" lateral 

 but from near the apex of an irregularly ovoid tuber or pseudobulb 

 1-5" long from one of the lowest sheaths of the leafy stem, the leaves 

 of which are very young (they just show at the surface in my specimen) 

 at flowering time. Lowest sheaths of scape convolute much as in 

 E. camjyestris, floral bracts -3" shorter than the -5- -7" long pedicel 

 and ovary. Flowers yellow and purplish -4" long only. Sepals
