era and species of Orchideous plants*'' I had at dif- 



1681. DlPLOCETSTRUM LONGIFOLIUM (R. W)., 



ferent times two drawings made of this beautiful leaves linear, strap-shaped, channeled, obtuse, ob- 

 plant; by some accident both were, at different lique, the apex emarginate : racemes axillary, erect, 

 times, sent to the lithographer who, knowing no sparingly branched, longer than the leaves: sepals 



better, printed both. This explanation seems called 

 for to account for the appearance of two plates of 

 the same plant. The loss however is mine. My 

 location, 300 miles from the press, prevented the dis- obtuse appendage with the cells at the base. Sepals 



and petals ovate, nearly all equal, obtuse : lip entire, 

 undulated, obtuse or emarginate, capsules obovate, 

 pendulous, connectivum prolonged into a flat very 



covery of the blunder in time to prevent it. 



and petals dull brownish, tinged with pink, lip dull 



pinkish-lilac. 



1678. PoLYSTACHTA JLUTEOLA (Hookcr), spike On branches of trees, Orange Valley, Neilgher- 

 panicled, leaves oblong, lanceolate, many-nerved, ries, also lyamally Hills, flowering June and July. 



shorter than the scape : flowers and ovaries glab- 

 rous. Flowers pale yellow. 



lyamally Hills, near Coimbatore on branches of 

 trees, flowering August and September — also on 

 the Pulney Mountains during the rains. 



Lindley places this genus in the tribe MalaxidefB^ 

 remarking that "the pollen masses are in reality 

 four in number and lie loosely side by side, two in 

 each cell of the anther," and objects to the correct- 

 ness of Sir W. Hooker's figure which represents 

 them "adhering to a common pedicel and gland, 

 4 in number, and not lying side by side, but upon 

 each other." My drawing was prepared long before 

 I knew the genus, and had the pollen exactly as 

 represented by Hooker. Lindley's remark induced 

 me to re-examine it in dried specimens when I 

 found Lindley's statement correct, and unfortu- 

 nately had the drawing, as I supposed, corrected. 

 Subsequently I received living specimens of the 

 following, No. 1679, and found that they corres- 

 ponded with Hooker's figure. This led me to sus- 

 pect that I had unjustly charged the artist with 

 incorrectness of observation and had by my altera- 

 tion, in that particular, spoiled my drawing, the 

 pollen in thatbeing truly Vandeous, that is, furnished 

 with a caudicula and gland, and therefore placed 

 the genus here as being its proper place. Since 

 sending the drawing to the Lithographer, I have 

 had another opportunity of examining the fresh 

 pollen of this one, and find my suspicions verified, 

 this also having a caudicula and gland. 



1679. PoLYSTACHTA PURPUREA (R. W.), spike 

 panicled, leaves coriaceous, linear oblong, obtuse, 

 emarginate, shorter than the scape: flowers and 

 ovary glabrous: lip pubescent within: gland of the 

 pollen scutelliform, orbicular, caudicula short: cap- 

 sules ovoid. Flowers purplish or rather perhaps 

 dark lilac, lip much paler. 



On the top of lyamally, a high hill about 3000 

 feet of elevation, with the following, on branches of 

 trees, flowering in June, and on several subsequent 

 occasions from the same range of hills. 



1680. DrPLOCENTRUM REcuRvuM(Lind.), "leaves 

 folded, fleshy, recurved: racemes panicled recurv- 

 ed: flowers small: spurs obconical, incurved: upper 

 sepal and petals nearly equal, anterior sepals larger, 

 unequal-sided: lip ovate, entire, acute, much larger 

 than the sepals ; flowers deep pink, fining off on 

 the margins to white, lip crimson. 



lyamally Hills, flowering from May to September. 



It is difficult to say whether this be really Lind- 

 ley's plant, but it seems to correspond with his de- 

 scription so far as it goes. Its actual identity can 

 only be determined by comparison of specimens- 



1682. DipjLocENTRUM coNGESTUM (R. W.), leavcs 



short, sub-elliptic oblong, deeply emarginate or 2- 

 lobed at the apex : racemes longer than leaves, axil- 

 lary, sparingly branched, erect, many-flowered : 

 flowers congested, small: sepals and petals ovate: 

 lateral sepals oblique, larger than the petals: lip 

 ovate, tapering, truncated at the point; connectivum 

 of the anther prolonged, truncated at the apex: 

 caudicula long subulate ; gland very large, some- 

 what 2-lobed. Colour not preserved but like the 

 preceding. 



lyamally, on branches of trees, flowering during 

 the rainy months, July to October, rare. 



1683. iEcEOLADES TENERA (Liud.), caulcsccnt 

 leaves oblong, fleshy, emarginate ; spikes 3-4-flow- 

 ered, horizontal, shorter than the leaves : posterior 

 sepal erect, helmet-form, anterior ones leaning on 

 the lip, equal ; petals parallel to the helmet and like 

 it; all distinct at the base: lip shorter than the 

 sepals, three-lobed, cucullate, lateral lobes erect, 

 emarginate, truncated ; middle one fleshy, 3-lobed, 

 flat with 2 callosities at the base: spur short, in- 

 curved. Flowers brownish-yellow with crimson 

 points, lip white. 



Nuera EUia, Ceylon, on trees, flowering March. 



This plate is taken from a drawing by Mrs. Col. 

 Walker, with the following note attached. " Sepals 

 and petals greenish-yellow streaked with brownish- 

 red. — Lip fleshy, 3 outer lobes pure white, the other 

 part yellow, streaked with pink. Column and an- 

 thers red and yellow. Leaves thick and fleshy, on 



some plants larger and on others smaller than here 

 represented." 



1684 



W 



lous, leaves terete, filiform, spike simple, ascending, 

 much shorter than the leaves : sepals narrow lanceo- 

 late, posterior one larger : petals ovate, orbicular, ob- 

 tuse, much larger than the sepals : lip thee-lobed, 

 lateral lobes erect, obtuse, middle one ovate, acute, 

 reflexed ; spur slightly recurved, obtuse, as long as 

 the flower : capsule sub-cylindrical, clavate. Flow- 

 ers orange-yellow streaked with darker crimson lines, 



Anamally forests, pendulous from branches of 

 trees, flowering September and October. 



lam indebted to Major Cotton (Civil Engineer) 

 for the specimens here represented, I suspect the 

 large capsule represented does not belong to the 

 plant. 



1685. Sarcanthus roseus (R. W.), pendulous: 

 leaves round, subulate, of very firm hard texture; 

 racemes spicate, ascending, compact; anterior sepal 

 lanceolate, acute, posterior one linear obtuse : petals 

 broad, orbicular: spur of the lip straight, inflated at
