BOLLEA. 125 



SOLLEA., Reichenhacli fil. 

 ( T)-il>i; Vandeae, subtribe Cyrtopodieae.) 

 In their manner of growth the species of Bollea are much like those 

 of Pescatorea, but the flowers are quite different. Both Eeichenbach and 

 Bentham and Hooker regard the group as a section of Zygopetalum. 

 Their chief peculiarities consist in their one-flowered scapes, their broad 

 sepals and petals, their ample rounded shortly-clawed lip, which has a 

 prominent crest on the disk, and their short thick column, which has the 

 anther-bed entire and subcucullate. The species are not numerous, and 

 all inhabit Tropical America. 



Gulture. — These plants succeed well in the warm-house in a mixture 

 of peat and moss, and they require an abundant supply of water during 

 the time of growth. Many persons cultivate them in pots, but we have 

 found them do well on blocks and in cork baskets, especially those formed 

 of fern stems, but treated in this way they require an abundant supply 

 of water when growing. 



B. COELESTIS, Rchh.f. — In growth this species resembles B. Lalindei, but 

 the colouring of the flower is altogether brighter and more distinct, The 

 leaves are close-set, distichous, and cuneate-oblong ; the scapes fifteen to 

 eighteen inches high ; the flowers large, three to four inches across, the oblong- 

 acute sepals and the shorter petals light blue at the base, deeper mauve in the 

 middle, the marginal tips white ; the lip is deep violet in front, the prominent 

 basal callus yellowish white, consisting of fifteen nearly contiguous lamellse. 

 The boat-shaped column is of a fine deep violet blue, except the base, which is 

 yellow. This will form a fine distinct exhibition plant. It flowers in June and 

 July, and will last a long time in perfection. — Colombia.

B. LALINDEI, Mchh. f. — A very distinct plant of recent introduction. The 

 leaves are elliptic lanceolate, narrowing to the base, flve-nerved, a foot long, 

 distichous ; the scapes are solitary ; the flowers are about three inches across, 

 the sepals and petals in plants flowered by us lilac at the base, pale rose in the 

 upper part, with the tips straw-colour, and the lip golden yellow, with about 

 thirteen close-set lamellae ; but in those described by the late Prof. Eeichenbach 

 they were of a bright violet, the upper sepal tipped with green, the lower halves 

 of the lateral sepals brownish purple, the lip deep orange, and the column deep 

 purplish. The column is very peculiar, being broader than the lamellate disk, 

 arched and rose-coloured. — New Grenada.

B. LAWRENCEANA, Bchb. f. — A beautiful and delicately-coloured species, 

 resembling B. coelestis in growth. The plant is dwarf, almost stemless, with
