C. Lawrenceanum, Reichb. in Gard. Chron. 1878, ii. p. 748. 
Dr. Reichenbach in his description of this plant well re- 
marks that it unites the flower of the Javan C. barbatum with 
the foliage of C. Dayanum. It is one of a series of forms of the 
genus, with few linear usually tessellately spotted leaves, few- 
or single-flowered scapes, spreading petals, broad dorsal sepal 
and small combined lateral sepals, which extends from Nepal on 
the West (C. venustum, tab. nost. 2129) to Borneo and the 
Philippine Islands on the East, the colour becoming more 
intense and the flowers larger in proceeding southward and 
eastward, till they attain their known maximum in the pre- 
sent splendid Bornean species, and in C. Argus (tab. 6175) of 
the Philippine Islands. It includes also C. purpuratum (tab. 
nost. 4901) of the Indian Peninsula, C. barbatum, Ldl. (t. 
4234) of Java, C. Hookerw, Rehb. f. (t. 5362), C. Faireanum, 
Ldl. (t. 5024), and others. @. Lawrenceanum is one of Mr. 
Burbidge’s discoveries during his recent expedition to Borneo, 
in the service of the Messrs. Veitch ; another of the fruits of 
which journey is the beautiful Burbidgea nitida, figured in the 
January Number of this work (t. 6403). Mr. Burbidge in- 
forms me that he found it on sandstone and limestone rocks, 
JUNE Ist, 1879.
