NOTES or ORCHIDACEOUS EPIPHYTES or NEW SOUTH WALES. 
By Allan Cunningham, Esq. 
30. DENDROBIUM tetragonum ; caulibus gracilibus erectis elongatis quadran- 
gularibus apice clavatis 2-3-phyllis, foliis ovato-lanceolatis acutis undulatis 
striatis s, nervosis glabris racemo terminali 2-4-floro longioribus, foliolis pe- 
rianthii elongato-linearibus patentibus, labello vittato: disco tricarinato, 
lobo medio dilatato subcordato acuto. 
An epiphyte, hanging loosely from the stems of small 
trees, in dry shaded woods, Moreton Bay. June 1828. 
31. DENDROBIUM tortile. (Perhaps a Polystachya.) ? 
On the upper branches of the loftiest trees of Flindersia 
australis, 100 feet high ; in shaded woods, Brisbane River, 
Moreton Bay. Oct. 1824. June 1828. 
32. DENDROBIUM? pygmaum. (D. Caleyi, Cunn. in Bot, Mag. Com- 
pan. II. 377.) 
On rocks in the Illawarra district. Flowers not known. 
33. DENDROBIUM elongatum ; caulibus artieulatis teretibus- sulcatis »elon- 
gatis erectis 4-5-phyllis, foliis ovato-lanceolatis acutiusculis apice obliquis 
emarginatis, racemo terminali 3-10-floro, foliolis perianthii ovatis obtusius- 
culis, labelli disco 3-carinato lobo intermedio lato cordiformi. 
On trees in shaded dark woods, on the banks of the 
Brisbane River. Sept. 1828. 
34. DENDROBIUM pugioniforme; caulibus repentibus nodoso-articulatis 
radicalibus setoso-stipulatis, foliis elliptico-lanceolatis apice attenuatis acutis 
carnosis infra fere convexis carinatis leevibus nitentibus, floribus (resupina- 
tis) subsolitariis axillaribus, perianthii foliolis oblongo-lanceolatis acutis pa- 
tentibus, labello longitudinaliter tricarinato, lobo intermedio dilatato undulato- 
crispato apice acuto recurvato, 
A beautiful epiphyte, hanging loosely from the stems of 
trees, so as to swing freely to the wind that sweeps through 
the forests on the summit of the belt of mountain bounding 
the coast district of Illawarra, on the west (lat. 343 S.) and 
flowering in August. 1818. 
Obs. This species approaches so near D. rigidum Br. 
prodr. (not of Gen. et Sp. Orch. p. 86. n. 51) that 1 have 
often viewed it as the same plant which was described by 
Mr. Brown, from a figure in the Banksian collection. It now 
appears to me distinct. 
35. DENDROBIUM? crassulefolium. 
Of this I have no specimens or description. It is a plant 
growing on trees in ravines of the Blue Mountains. Never 
seen in flower. The pseudobulbs are oval and one-leafed ; 
the leaf is small and oval.
