NOTES OF ORCHIDACEOUS EPIPHYTES of NEW SOUTH WALES. 



Bij Allan Cunningham, Esq. 



30. DENDROBIUM tetragonum ; caulibus gracllibus erectis elongatis quadran- 



gularibus apicc clavatis 2-3-phyllis, foliis ovato-lanceolatis acutis undulatis 

 striatiss. nervosis glabris racemo terminall 2-4-lloro longioribus, foliolis pe- 

 rianthii elongato-lincaribus 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? pygnmum. {D. Caleyi, Cunn. in Bot. Mag. Corn- 

 pan. II. 377.) 



On rocks in the Illawarra district. Flowers not known. 



33. DENDROBIUM elongatum ; caulibus articulatis 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 cariiiatis kevibus nitentibus, floribus (rcsupina- 

 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. 34 ^ S.) and 

 flowerino; in Aug-ust. 1818. 



Obs. This species approaches so near D. rigidum Br. 

 prodr. (not of Gen. et Sp. Orch. p. 86. n. 51) that I 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? crassulccfolium. 



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.
