ANGULOA. 99 



Colombia (1811 — 43) was partly dcfra3-eJ by a few English gentle- 

 men deeply interested in orchid culture^ including Mr. Barker of 

 Birmingham, Mr. Racker of Wandsworth, the Rev. John Clowes of 

 Manchester, and others.* The genus was founded by the Spanish 

 botanists Ruiz and Pavon on Anguloa unijiora, and was dedicated 

 by them to Don Francisco de Angulo, at that time Director-General 

 of mines in Peru.f 



Cultural Note. — The Anguloas are among the most tractable of orchids 

 to cultivate, exacting no extra vigilance or care at the cultivator's 

 hands. The plants should be potted in a compost of two-thirds fibrous 

 peat and one-third of chopped sphagiuim moss, to which some cultivators 

 add a little silver sand to assist drainage. This compost should be 

 placed on a drainage of clean broken crocks filling from one-half to 

 two-thirds of the depth of the pot, and from which it should be 

 separated by a layer of moss to prevent the drainage being choked 

 by the filtering through of the compost ; the best time for potting is 

 when new roots begin to appear from the base of the pseudo-bulbs. 

 The temperature should be intermediate, that is to say, a range of 

 about 12° — 15° C. (55° — 60° F.) during the resting season, allowed to 

 sink about 3° C. (5° F.) lower at night, and raised to 15° — 18° C. 

 (60° — 65° F.) during the growing season with such increments by sun- 

 heat as weather and circumstances permit. After potting, water should 

 at first be moderately applied, gradually increasing the supply as the 

 new growths gain strength, and again in diminished quantity after the 

 pseudo-bulbs and leaves are mature. The young growths should be 

 shaded from direct sunlight, but as maturity is approached they should 

 receive aU the light available. The leaves are somewhat liable to be 

 infested with red spider, which may be got rid of by sponging. 



Anguloa Clowesii. 



Pseudo-bulbs cyliadric-oblong, 5 — 6 inches long, leafless when old. 

 Leaves broadly obovate-lanceolate, acute. 18 — 2-4 inches long. Scapes 

 one-flowered, stoutish, erect, as long again as the pseudo-bulbs. Flowers 

 sub-globose, of a uniform citron-yellow, and of a peculiar odour wliich 

 has not been inaptly compared with that of a chemist's shop ; sepals 

 and petals ellij)tic-oblong, concave, the lateral sepals slightly oblirpie, 

 shorter and broader, and tlie petals narrower than the dorsal sepal ; 

 lip concave, almost like a boat, articulated with the foot of the

t Owing to the brief diagnosis of the genus given by these authors, and tlie obscure 



manner in which it is worded, Anguloa remained for half a century a botanical puzzle 



till the first flowers expanded in the orchid houses of the gentlemen through wliose 

 enterprise all the species were intioduced.
