coinciding in the very peculiar distinctive feature, 

 very imperfectly represented in the figure, the long 

 thread-like tails of the lateral sepals, but I am un- 



1664-65. Calanthe Perrottetii (A. Richd.), 

 leaves petioled, elliptic, nerved, plicate, acute : scape 

 longer than the leaves, furnished with distant sheath- 



certain whether to view them as distinct species ing scales: raceme loose: bracts ovate, lanceolate, 

 or only varieties. In appearance they differ, but length of the ovary: sepals and petals sub-equal, 

 that may be merely owing to difference in luxu- 



riance or exposure of the stations where they re- 

 spectively grew. 



1659-60, Phajas eicolor (Lind.), stemless, scapes 



longer than the leaves: leaves lanceolate, acumi- 

 nate: sepals and petals lanceolate, acuminate: lip 

 cucullate, bellied, entire, limb obtuse, cuspidate-un- 

 dulate on the margin, furnished towards the base 

 with two flat plates : spur cylindrical, curved, emar- 

 ginate at the apex, about the length of the ovary. 

 Flowers yellowish, lip rose-coloured, spur yellow. 



Ceylon, in pasture on the sides of hills. 



I have two coloured drawings before me, both 

 from the pencil of Mrs, Walker, in the one the 

 colour corresponds with Lindley's description, the 

 other has the sepals and petals purplish above, 

 brownish pale-white beneath, the lip, externally, 

 pale brownish-yellow, within, rose. Can the dif- 

 ference originate in the flowers changing colour 

 after expansion? 



This genus, so far as I am aware, has not yet been 

 met with in the Peninsula, but as it may be ex- 

 pected in Malabar, I have introduced this species 

 to make it known, if found. 



1661. Arundenia bambusifolia (Lind.)jlip fur- 

 nished within with two fleshy undulated crested 

 plates, and a shorter straight intermediate one : lat- 

 eral lobes short, entire or sub-obsolete, middle one 

 two-lob ed, segments divaricating, crisp : petals lan- 

 ceolate : leaves acuminate* 



The specimens from which the drawing was made 

 were from Ceylon, it is also found in Malabar. The 

 above character is taken from Nepaul specimens, 

 but seems quite in accordance with our plant. 



ovate, obtuse : lip 3-lobed, lateral lobes lanceolate, 

 middle one much larger, truncately2-3-lobed; lobes 

 spreading; spur slender, straight, longer or about the 

 length of the lip. Flowers light lilac, lip with a 



deeper tinge. 



Neilgherries, frequent in clumps of forest, in moist 

 soil, flowering July and August. I have seen it in 

 flower in woods about Coonoor in May, but very 

 rarely at that early season. 



It is a large plant sometimes nearly four feet high, 

 the leaves from a foot to a foot and a half long and 

 from 4 to 6 inches broad. Flowers delicate pale 

 lilac colour. It is perhaps too nearly allied to C. 

 veratrifolia, Lindley, if indeed it be not that species, 

 which however has a four-lobed lip. 



1666. Eulophia ramep?tacea (Lind.), leafless: 

 bracts subulate, shorter than the ovary: flowers 

 erect: sepals and petals linear, spathulate, acute: 

 lip 3-lobed, the middle lobe undulated, obtuse ; 

 plates of the disk three, broken or torn towards the 

 point ; spur obtuse, conical. 



Coorg, Mysore, &c. This species is leafless when 

 in flower ; as in the case of some others, the leaves 

 follow the flowers. The leaves here represented 

 are those of the species but taken from a young 

 specimen, which, apparently, had not attained suf- 

 ficient maturity to flower that season. 



1667-68. Eulophia macrostachta (Lind.), leaves 

 oblong, acuminated at both ends, plaited, somewhat 

 3-ribbed: scape simple, radical, longer than the 

 leaves: sepals linear, lanceolate, acuminate : petals 

 conformable, broader, sub-undulate: lip sub-orbicu- 

 lar, 3-lobed, lateral lobes about the length of the 



3662. Apatdria Lindleyana (R. W.), petals shortened, deeply-cleft middle one; two sTiort petals 



linear, sub-spathulate, equaling the oblong linear lan- 

 ceolate acute sepals: lateral lobes of the lip obtuse, 

 roundish: middle one ovate, straight, with three crests 

 extending nearly its whole length, and decurrent on 

 the claw : the middle one thicker and higher than 

 the others ; lateral ones not marginal, bracts as long 

 as the ovary, ovate, cucullate, acute. 



Coorg, Jerdon, flowering December and January. 



I almost fear this is too near Lindley's ^. senilis, 

 the distinctive marks being apparently very slight, 

 but still, so far as I can gather from the brief char- 

 acter, they seem distinct 



lf363. Ipsea spiciosa (Lind.). This is the only 

 species of the genus yet known. A native of 

 Ceylon. 



1 have also a specimen, perhaps a new species, 

 found on the Malabar Ghauts, but have not yet suf- 

 ficiently examined it. The figure is taken from a 

 drawing by Mrs. Colonel Walker. I gathered spe- 

 cimens in April 1836, in company with the late 

 Colonel Walker. The genus is said by Lindley to 

 be very peculiar, partly on account of the species 

 having two-lobed, fleshy roots, like those of the 

 Ophrydeae, a very unusual coincidence in Orchids, 

 with waxy pollen. The figure does not exhibit 

 that feature. 



near the base, spur short, roundish, obtuse, inflated. 

 Flowers greenish-yellow, lateral lobes of the lip 

 tinged and streaked with crimson lines, the middle 



lobes yellow. 



Neilgherries, Ceylon. The specimen represented 

 was found in dense jungle near the banks of the 

 stream at Burlear on the Eastern slopes. I have 

 also specimens from Ceylon. 



This is a very pretty species when seen in per- 

 fection: the lip is curious. Lindley describes the 

 middle lobe as " alte bilobo abbreviate," but it is not 

 cleft but rolled back as attempted to be shown in 

 the plate. The spur is also of a very unusual shape, 

 a little round knob at the base of the lip. 



1669. Aerides Wxghtianum (Lind. Vanda parvi 

 Jlora R. W, in Icon.), leaves strap-shaped, oblique at 

 the base, obtuse, 2-lobed with a tooth between: 

 racemes straight, simple, many-flowered, longer than 

 the leaves: sepals and petals oval, the anterior ones 

 larger: lip funnel-shaped, lateral lobes adnate to 

 the foot of the column, the middle one sub-cuniate, 

 roundish, 3-lobed at the apex ; disk crested with 

 several elevated crisp lines ; spur short, conical. 

 Middle lobe of the lip deep lilac, capsules club- 

 shaped six-angled. Flowers yellow.
