 obtuse, as long as the ovate lanceolate petals : lip 

 broad, linear, obtuse, emarginate. The dissections 

 of the flowers are taken from some obtained from

 pedicels, lanceolate acuminate : sepals and petals 

 a little longer than the lip, glabrous, falcate, atten-

a very young spike, the older spike, shown in the nerved, sub-coriaceous at the base, contracted in 



plate, is in fruit.

 jone-leaved: leaf ovate, obtuse: spike dense cylin- 

 drical : perianth flattened : lip excavate, thickened at 

 the apex J nearly entire: column very short. Lind. 



Simla, Countess Dalhousie — Edgeworth. 



The specimen represented on the left side ofthe 

 plate I received many years ago from the late 

 Countess Dalhousie ; for the drawing of the figures 

 on the right side, I am indebted to Mr. Edgeworth 

 of the Bengal Civil Service. His figure was taken 

 from a living specimen, mine from a dried one. In 

 some parts, especially the lip, the difference appears 

 considerable, but I consider myself fortunate in 

 being thus enabled by contrast, to show how much 

 can be made of well-dried specimens. It is now up- 

 wards of 20 years since my specimen was gathered. 



1631. MiCRosTYLis DISCOLOR (Liud.), stem leafy, 

 leaves ovate, oblong, abruptly petioled, undulate, 

 plaited: lip ovate, entire, cucuUate at the base: 

 column two-horned at the apex: sepals and petals 

 all turned to one side-

This species is very nearly allied to the next, but 

 is quite distinct. 



1635. Eria poltstachta (Ach. Richard E.vube- 

 scens in Icon.), stem thickened pseudo-bulb-lJKe at 

 the base, loosely sheathed; leaves terminal, from 

 oblong elliptical acute to obovato-elliptical, some- 

 what obtuse, glabrous: spikes axillary, about the 



length of the leaves, erect, clothed with short pube- 

 scence: bracts lanceolate acute: sepals ovate, at- 

 tenuate at the point, pubescent, exceeding the 

 lanceolate petals : lip ovate lanceolate, about half 

 the length of the petals,

Though my figure differs somewhat from that of 

 M. Richard, I believe they both represent the same 

 species, and both being taken from dried speci- 

 mens may easily account for the difference. The

1632. MicRosTYLis luteola (R. W.), stem leafy 

 at the base; leaves ovate, subcordate at the base, 

 acute, plicate: sepals obovate, obtuse, the middle 

 one narrower: petals linear, obtuse, emarginate : 

 lip somewhat 2-Iobed, lobes broad, spreading, fim-

Ootacamund, Neilgherries, flowering August. This 

 species is nearly allied to M. versicolor but is cer- 

 tainly distinct. It grows under the shade of bushes 

 and among long grass on the highest peaks of the 

 Hills. 



1633. Leparis biloba (R. W.), leaves 2 or 3, 

 ovate, acute, undulate, plicate, cucullate : raceme 

 erect, few-flowered: sepals ovate, acute : petals nar- 

 row linear, blunt pointed : lip spreading deeply 2- 

 lobed. Flowers dull plumb colour. 



Neilgherries, nestling among moss on the branches 

 of trees, flowering July and August. Flowers long- 

 ish pedicelled in proportion to the rest of the plant. 

 It comes very near L. atropurpurea but the deeply 

 2-lobed lip keeps it distinct.

By some accident the names of Nos. 1634 and 

 1635 have got transposed, I must therefore beg the 

 favour of the reader's correcting them as follows: 



1634. Erfa pubescens (R. W. E. polystachya 

 in Icon.), stem leafy, short, clothed at the base with 

 sheathing scales: leaves lanceolate tapering at both 



in magnified figures. 



1636. Erta PAUcirr-ORA (R. W.), c^spitose, stems 

 erect, succulent, jointed, thickened at the apex, with 

 a leaf at each joint, last joint thickened, tuberous, 

 surmounted by two leaves, from between which 

 rises the short 1- or 2-flowered raceme : leaves 

 ovate, oblong, obtuse : flowers longish pedicelled : 

 sepals about equal or slightly longer than the nar- 

 row linear petals : lip somewhat corrugated furnish- 

 ed with two lamellae near the base. Flowers white. 



Growing on moist rocks, forming dense masses 

 exposed to the spray of the river below the Kaitie 

 Falls, Neilgherries, flowering August and September- 

 Flowers pure white. A very distinct and peculiar 

 species. The stems become like pseudo-bulbs at 



the apex, and then flower in their season. 



1637. Eria reticosa (R. W,), caespitose, stem- 

 less, pseudo-bulbs orbicular, depressed, enclosed in 

 a net-like sack : leaves about two, elliptic, spread- 

 ing : scape filiform, 1 -flowered, furnished at the apex 

 with a large somewhat boat-shaped bractea : flow- 

 ers large, resupinate, expanding: sepals and petals 

 about equal, exceeding the obscurely 3-lobed lip. 

 Flowers pure white, lip and column yellow, bract 

 brownish.
