Snpra arbores cirea Otacamiind. Jul. — Sept. Nilgherries. Perrotet. — Planta 3 — I 

 uncias alta ; labellutn paUide virens, sepala albido-subcarnea. — Affine D. alpestri 

 Royle. Mais les feuilles sont plus etroiles, oblongt-es; chaque bulbe ne porte qu'une 

 seule hampe , soutenant 3 — 4 nenrs , tandis que dans le Dendrobrum alpestre il sonl 

 3—4 hampes ayant chacune 3—5 Qeurs. 



Huc : Dendrobium humile Wight. Ic. V. I. 1643 (1851). — Caespitose, pseudobulbs 

 evate, cOTered with ihe sheaths of fallen leaves , leaves often wanting. when present 

 one or iwo from the apex of the bulbs linear laneeolaie , about the lenght of the scape ; 

 raeeme erect, 4 — 8 flowered ; bracts small . linear, subulale, lateral sepals acute 

 subfalcate forming wiih the process of the column anacutespur, posterior divaricato 

 lanceolate; petals lanceolaie, narrower ihan the posierior sepal : lip large 3 lobed, 

 middle lobe crenulate , cr^sp , suborbicular. lateral ones entire , or slightly crenate. 

 Flowers greenish yellow, tipped with pink, lip pink with darker crimson lines. — 

 JyamaHy Hills, trees. July , August. Except that this belongs to Lindley's first sec- 

 tion , having pseudobulbs bearing the leaves , it scems to approach very near Dendr. 

 denudans and alpestre; from tlie latter it is certainly distinct. I am not quile so cer- 

 tain in regard to the former ; the pointed divaricating spur of this species is its most 

 sheaking feature. 



Huc : Dendrobium crispum Dalzell in Hoo4. Joarn. Bot. IV. 111. 

 D. crispum (nobis); foliis serolinis paucis lineari-lanceolatis subcompli- 

 catis, florlbus racemosis 6— 10, ovario florem aequante basi bractea parva 

 scariosa suffulto, sepalis pelalis brevioribus, supremo lineari-lanceolato 

 obtusiusculo , lateralibus subfalcatis, petalis spathulatis, labello sepalis 

 breviore 3-lobato, lobis 2 ereclis acutis, intermedio truncato margine 

 irregulariter crenato albo roseo-maculato basi cornubus 2 erectis acutis 

 praedito, columna utrinque apice breviter cornuta. 



Tota 4—5 poll. alta , Qoribus albis, labio excepto. — Crescit in arboribus ublque; fi. 

 temp. frigido — The pseudobulbs of this very common plant are small , button-shaped, 

 and green , with a white network over them; the peduncle is delicate, filiform, purple» 

 two and a half to three inches long, glabrous and smooih, wiib tubular sheaths. 

 The fruit is oval , shining, four lines loug. Lindley has sixteen species of this section 

 in his ,,genera and species", but noi one from Continental India, where ihey are 

 plentiful.
