to be met with more or less in flower the greater 

 part of the yean It is a plant of great beauty when 

 seen in perfection. Its most peculiar feature is 

 the net enclosing the pseudo-bulbs. It is so remote 

 in habit from the other Erias, that it was some 



time before I could reconcile myself to placing it yellow. 

 in that genus. 



scape terminal, length of the leaves, 2-4-flowered : 

 bracts linear, persistent, divaricate: lip erect, 3-lob- 

 ed, lateral lobes oblong, obtuse, middle one larger, 

 acute, narrower below, furnished with two sinuous 

 longitudinal crests. Flowers white, lip tinged with 



Neilgherries, on branches of trees in clumps of 

 forest near Neddawuttim. 



My figure differs so much from Richard's as to 



1638. CffiLOGYNE NERVOSA (Ach. Rich.), pseudo- __ _^ 



bulbs ovate, covered with coriaceous scales: leaves leadVe'^to doubt their identity, especially as re- 

 broad elliptic acute, or sub-acuminate, striated and - - . .. ... 



nerved, coriaceous, usually two, sheathing at the 



base : scape somewhat longer than the leaves, 2-6- 

 flowered : flowers large ; bracts shorter than the 

 flowers, ovate, acute, persistent, striated : sepals ob- 

 long-elliptic, about equal, acute : lip, like the sepals, 

 3-lobed, lateral lobes small, the middle one oval, lan- 

 ceolate. Flowers pure white, bract reddish-brown. 



Neilgherries, flowering May and June. 



This when in full flower is an exceedingly hand- 

 some species, the large pure white flowers, the lip 

 only being tinged with orange, the brownish bracts, 

 and dark green foliage present a charming com- 

 bination. It abounds on the rocks overhanging the 

 falls at Pycarrah, also at the Avalanche. The spe- 

 cimen represented flowered inCoimbatore,the roots 

 having been brought down some weeks before. 



1639. CffiLOGYWE CORRUGATA (R. W.), pSCUdo- 



bulbs CcBspitose, ovate, reticulately corrugated: 

 leaves oblong, elliptic , sub-acuminate : racemes 

 about the length of the leaves, 3-6-flowered; bracts 

 caducous or wanting: flowers large, sepals and pe- 

 tals conformable, oblong, ovate, acute : lip 3-lobed, 

 lateral lobes small, middle one produced, orate, ob- 

 tuse, the claw furnished with three longitudinal un- 

 dulato-crenate, coloured crests. 



Courtallam, Pulney Mountains, Neilgherries, flow- 

 ering August and September. 



~ The limb of the lip is marked with orange and 

 yellow lines like the crests, the rest of the flower 

 is pure white. The peculiar feature of the species 

 is the deeply corrugated, wrinked pseudo-bulbs, 

 whence I have taken the name. 



1640. CffiLOGTisE ODORATissiMA (Liud), pseudo- 

 bulbs casspitose, ovate ; leaves lanceolate, petioled, 

 length of the 2- or 3-flowered raceme : bracts boat- 

 shaped, divaricate, petals linear, lanceolate: lip 3- 

 lobed, 3-crested, middle lobe undulated, orbicular, 

 column entire. Flowers white, lip tinged with 

 yellow.

 to October. 



gards the form of the lip, acute in his, very obtuse 

 in mine. If I have erred in naming this, it is from 

 confounding two specimens much alike, one, but 

 from which the flowers have all fallen, perfectly 

 quadrates with his figure, the other, less exactly 

 corresponding but still apparently the same, having 

 flowers, was selected for representation and named 

 without again carefully comparing the character 

 throughout until copying it Are they really dis- 

 tinct or does an error exist in that part of his 

 figure? This question can, I fear, only be answer- 

 ed, in this country, by again obtaining fresh flower- 

 ing specimens^ of the more correctly corresponding 

 form. 



1642. Dewdrobium fimforme (R. W.), caespi- 



tose, pseudo-bulbs depressed, flattened, sub-orbicular, 

 netted on the surface: leaves 2-3, ovate, oblong, 

 somewhat obtuse, slightly cuspidate : raceme erect, 

 filiform ; few, 2-3- to many- (10-12) flowered : bracts 

 ovate, acute, longer than the ovary; sepals much 

 attenuated, subulate, pointed, dilated at the base, 

 adnate to the process of the column forming a 

 short obtuse saccate spur: petals about equaling 

 the sepals and nearly thrice as long as the narrow 

 ovate lip. Flowers straw colour. 



Neilgherries and lyamally Hills near Coimbatore, 



on branches of trees. I am also indebted to Mr. 

 Law of Bombay for specimens from that neigh- 

 bourhood, but the station not stated. 



The plate exhibits three forms, all more or less 

 differing but still evidently the same species. The 

 bracts are more boat-shaped than represented in 

 the drawing. The figure of the column and lip is 

 more highly magnified than the other dissections. 

 It is seen in nearly correct proportions in the front 

 view of the artificially-opened flower. 



1643. Dendrobium humile (R. W.), caespitose, 

 pseudo-bulbs ovate, covered with the sheaths of fallen 

 leaves, leaves often wanting, when present one or 

 two from the apex of the bulb, linear lanceolate, 

 about the length of the scape: raceme erect, 4-8- 

 flowered: bracts small, linear, subulate: lateral 

 sepals acute, sub-falcate, forming with the process 

 of the column an acute spur, posterior devaricato- 



This very pretty species forms large masses lanceolate: petals lanceolate, narrower than the 



sometimes covering continuously several feet of 

 the branch on which it grows, covered with numer- 

 ous racemes of its pure white flowers. The pseudo- 

 bulbs are green, intermixed with sheathing scales of 

 uniform colour. Flowers expanding, petals nar- 

 rower than the sepals. 



1641. C(Ei.oGTJ?rE AKGUSTiFOLiA (A. Richard), 

 pseudo-bulbs aggregated, ovoid oblong, the older 

 ones naked, the younger sheathed, one- or two-leaved 

 at the apex: leaves linear, lanceolate, acute, chan- 

 neled at the base, spotted beneath with white points : 



posterior sepal: lip large, three-lobed, middle lobe 

 crenulate, crisp, sub -orbicular, lateral ones entire, 

 or slightly crenate. Flowers greenish-yeUow, tipped 

 with pink, lip pink with darker crimson lines.

Except that this belongs to Lindley's first section, 

 having the pseudo-bulbs bearing the leaves, it seems 

 to approach very near Z). denxidans and alpeslre ; 

 from the latter it is certainly distinct, I am not 



Suite so certain in regard to the former; the pointed 

 ivaricating spur of this species is its most striking 

 feature.
