 late pseudobulbs: leaf -blades linear or nearly so, 1.5-4 cm. long: flower-stalk simple: 

 lateral sepals 25-50 mm. long, linear-lanceolate and attenuate: petals greenish, 

 linear-attenuate: lip brown or purplish; blade orbicular-reniform, 1620 mm. long, 

 entire, abruptly pointed; capsule-body 20-30 mm. long. 



In hammocks, southern peninsular Florida and the Keys. Also in tropical America. 



34. HORMIDIUM Lindl. 



Epiphytic herbs with creeping stems. Leaves spreading, the blades relatively 

 narrow. Flowers in terminal clusters which are subtended by an involucre of leaf -like 

 bracts. Perianth inconspicuous. Lateral sepals mostly narrow and shorter than the 

 median one. Petals much smaller than the sepals. Lip relatively small, with 2 large 

 lateral lobes and a very small middle lobe. 



1. Hormidium tripteram (Brongn.) Cogn. Stems scaly with old leaf -bases: 

 leaf -blades oblong or nearly so, 2.5-7.5 cm. long: sepals acuminate, the lateral ones 

 5-5.5 mm. long: petals linear, 4-4.5 mm. long: lip 4.5-5 mm. wide, the lateral lobes 

 ovate or oval: capsule-body 12-15 mm. long, winged. 



In hammocks, southern peninsular Florida. Also in the West Indies. 



35. LIMODORUM L. 



Scapose herbs with corms. Leaves few, consisting of several sheathing scales, 

 and one with an elongated blade. Flowers in a terminal raceme-like spike. Perianth 

 mainly purple, pink-purple or white. Lateral sepals inequilateral, shorter than the 

 median one. Petals nearly equilateral, somewhat narrowed at the base. Lip with 2 

 minute lateral lobes and a large dilated middle lobe bearded with clavate hairs. 

 GRASS-PINK. 



Dilated portion of the middle lobe of the lip narrowed down to the lateral lobes. 

 Middle lobe of the lip cuneate, the lateral lobes half-orbicular. 



Lateral sepals broadly ovate: crest of the lip extending to the margins. 1. L. multiflomm. 

 Lateral sepals oblong-ovate: crest of the lip central. 2. L. pinetorum. 



Middle lobe of the lip rounded at the base, the lateral lobes much wider 



than long. 3. L. graminifolium. 



Dilated portion of the middle lobe of the lip separated from the lateral lobes 



by a linear stalk-like base. 

 Lip 15-19 mm. long: column- wing narrowed at the base. 



Middle lobe of the lip cuneate-flabellate: mature leaf-blades over 10 



mm. wide. 4. L. tuberosum. 



Middle lobe of the lip obreniform: mature leaf blades less than 8 mm. 



wide. 5. L. Simpsonii. 



Lip 9-10 mm. long: column-wings truncate at the base. 6. L. palhdum.
