This species closely resembles D. amanum, Wall, but it has pure white flowers, 
with only а spot of yellow near the base of the lip. It is а very local and scarce 
plant. Judging from the descriptions of D. spathaceum, Lindl, that species must be 
identical with D. candidum, which as the earlier published name must be kept up. We 
have therefore reduced 2. spathaceum here. 
Рглте 68.—Dendrobium candidum, Lindl. А plant, of natural size. Fig. 1 а bract, stalked ovary, 
column and lip, seen from the side, the sepals and petals having been removed, 2 lip, 3 vertical section of
