 laevis trilobi lacinia intermedia siibrotunda marginibus

 nate. S'mcapore. -A slender inconspicuous species, 



allied to D. revolutum and biflorum ; with green flowers 

 growing in pairs opposite the leaves. 



37. D. bilobum (Lindl. in Hook. Journ. Bot. vol. 3) ; foliis 

 linearibus obtusis apice subaequalibus bilobis, floribus 

 membranaceis minutis (solitariis ?), sepalis obtusis, peta- 

 lis duplo minoribus apiculatis, labello libcro elongato 

 obovato apice carnoso trilobo : lacinia media verrucosa, 



cornu elongato obtuso. JVew Guinea. A small 



inconspicuous species, with the appearance of Isochilus 

 linearis. 



38. D. pugioniforme (A. Cunn. in Bot. Reg. 1839- misc. 34<); 

 caulibus repentibus nodoso-articulatis radicalibus setoso- 

 stipulatis, foliis elliptico-lanceolatis apice attenuatis 

 acutis carnosis infra fere convexis carinatis Isevibus niten- 

 tibus, floribus (resupinatis) subsolitariis axillaribus, 

 perianthii foliolis oblongo-lanceolatis acutis patentibus, 

 labello longitudinaliter tricarinato, lobo intermedio dila- 

 tato undulato-crispato apice acuto recurvato. JV. Hol- 

 land. 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 lllawarra, on the 

 west (lat. 34i S.) 



Very nearly allied to this section of the genus are those 

 Dendrobia, which, with slender stems and thin flat leaves, 

 have flowers growing in racemes. They form a group 

 which may be subdivided upon the same principle as the 

 last. 



Sect. II. Stachyobium. Stems slende?^ ; Leaves thin 

 and jiat ; Flowers in racemes. 



A. Lip undivided. 



39. D. aduncum. (Lindl. in Bot. Reg. 1842. misc. 62);
