are smaller than those of L. cruenta with the sepals more acute ; 

 they are pale sulphur-yellow with some red blotches on the sepals, a 

 large brown-purple blotch at the base of the petals and a few spots 

 above it ; the lip has a purple blotch between the side lobes.

In Anguloa we have a small group of species highly prized bv 



horticulturists on account of their large and handsome flowers that 



appear in the summer months. In its botanical aspect the genus 



Anguloa is a link in the chain of affinities connecting Lycaste with 



Stanhopea ; to the first named it is indeed very closely allied but 



clearly separated from it by the very different form of the labellum. 



The most obvious floral characters of Anguloa are seen in the fleshy 



sepals and petals that are connivent, the sepals overlapping the petals, 



so that instead of spreading they form together a hollow globe, within 



which the lip and column are almost concealed. The lip is smaller 



than the other segments and three-lobed, the lateral lobes being much 



larger than the terminal one which is reduced to a small funnel-like 



body, two-lipped and hairy at its mouth.* 



In their vegetation the Anguloas are robust plants Avith large dark 



green pseudo-bulbs that are, at first, enclosed by alternate, imbricating 



leafy scales that pass upwards into true leaves. The leaves are large, 



plicate, prominently nerved, and of broadly lanceolate form. The scapes 



are produced from the base of the pseudo-bulbs, and are clothed with 



large, lax, pointed sheaths, of which the uppermost, the bract sheathing 



the ovary, is the largest. 



The Anguloas occur on the Andes of South America at 5,000 — 



7,000 feet elevation from northern Colombia southwards to about 



10° south latitude in Peru, growing chiefly on damp moss-covered 



rocks and often in shady woods. Three species only are recognised 



by botanists, viz., Aaguloa Clowesii, A. Rucheri and A. uniflora, all 



the various forms or species so-called by horticulturists being reducible 



to one or other of these. The typical forms of these three species 



were aH introduced into European gardens about the same time 



through M. Linden, the cost of whose mission to Venezuela and 



* There is a slight deviation from this stincture in Anguloa uniflara.
