Guatemala ; it grows in the same way, and produces its rosy 

 flowers on long drooping spikes. There are many varieties of 

 this, some of them with more colour than others ; the best

0. constrictum. — Although not a large-flowered species,

0. coronarium. — A charming species from South America ; it 

 grows eighteen inches high, with short thick pseudobulbs, and
