levis trilobi laciniá intermediá subrotundä marginibus

allied to D. revolutum and biflorum ; with green flowers 
growing in pairs opposite the leaves.

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 levibus niten- 
tibus, floribus (resupinatis) subsolitariis axillaribus, 
perianthii foliolis oblongo-lanceolatis acutis patentibus, 
labello longitudinaliter tricarinato, lobo intermedio dila- 
tato undulato-crispato apice acuto recurvato.——/. 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 Illawarra, on the 
west (lat. 342 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. Sracnyosrum. Stems slender; Leaves thin 
and flat ; Flowers in racemes.
