110 COOL ORCHID GROWING. 



Flowers from March to May, lasting from three to four 

 weeks. 



a. 0. nehulosum candidum. — A free-growing form of the 

 above, without the spots on the segments of the perianth, the 

 flowers being pure white, with the exception of the yellow 

 crest, and a few spots of brown on the lip. 



e. 0. nehulosum pardinum. — This is another form, having 

 flowers as in the normal type, but more densely spotted or 

 blotched with brown. It is sometimes labelled in nurseries 

 and gardens 0. pardinum, but it is only a more profusely spotted 

 variety of the clouded Odontoglot 0. nehulosum. 



0. nevadense (ISTew Granada). — This beautiful and showy 

 species at the first glance looks suspiciously like the old 

 0. luteo purpureum, but it is easily distinguished from it by 

 having simply a bilobed crest, not radiate, as in the last-named. 

 Flowers from two to three inches across ; sepals and petals 

 brown, tipped, and margined with yellow ; lip white, serrated^ 

 with a few spots on its lateral laciniee and round the crest on 

 its disc. It is from the Sierra IS'evada, and bears cool treat- 

 ment like the rest, lasting a long time in beauty. 



0. odoratum (New Granada). — A very free-flowering species 

 not a great deal unlike O.crocidipterum. Pseudo-bulbs ovoid, 

 two-leaved. Flower-spikes numerous, bearing 'flowers about 

 one and a half to two inches across ; sepals and petals lanceo- 

 late-acuminate, of a bright yellow colour blotched with rich 

 brown; lip in form lanceolate-trilobed, not unlike the other 

 segments in colour, excepting the addition of a white bilobed 

 crest. Flowers last a month, and are very fragrant. 0. con- 

 strictum also belongs to this group. 



a. 0. odoratum, var. latimaculatum. — This form has deep 

 golden flowers, very heavily blotched with bright crimson 

 brown. It is a tolerably distinct form, and very effective when 

 well grown.
