Trevoria (named for Sir Trevor Lawrence). Orchidaceae. Epiphytic orchids, grown in the warmhouse. Pseudobulbs elongated-pyriform, not compressed, 1-lvd.: lvs. large, rather leathery, folded, contracted to the petiole: scapes arising from the base of the pseudobulbs, simple, bearing a lax few-fld. raceme: fls large, fleshy, pedicelled; sepals rather thick, free- spreading, lateral ones oblique, very large; petals fleshy, twisted, conspicuously narrower than the sepals: labellum fleshy, concave, erect, not movably jointed with the base of the column, lateral lobes erect, axe-shaped, laxly surrounding the column; midlobe linear- hastate; column rather long, terete, clavate or abruptly truncate at apex; rostellum 2-toothed, membranaceous; pollinia 2: caps. fusiform.—About 3 species, Trop.

Trevoria is a genus of plants in the orchid family. It was described by FC Lehmann 1897 ser 3 vol21:345-346 in Gardeners Chronicle with a black and white picture of Trevoria chloris. (A photo of this single plant is also in the new vol 6 of the book NATIVE COLOMBIAN ORCHIDS: Volume 6: Supplement: Leucohyle-Zootrophion (1998). It grows under intermediate temperature and is found from Nicaragua & Costa Rica to Bolivia . The name is in honor of Sir Trevor Lawrence, a former president of The Royal Horticultural Society.
For relatives of Trevoria see Stanhopeinae.
Species
The representative species is Trevoria chloris.
Culture
The lava stone for culture is watered daily with 200 yS of a urea free mineral NPK fertilizer, leaves should dry fast after they get wet to prevent leafe spot fungi, every 10 days plants get organic fertilizer over the leaves in a solution of up to 600yS, sometimes fish emulsion, sometimes sea weed fertilizer (Bioalgen S90) or an amino acid fertilizer. Other Genera that grow well on such stones is closely related Schlimia and also terrestrial Polycycnis like morganii.
T chloris flowers are extremely fragrant and don't need to wait for pollinators, they only open for a day.
Concerning sandwich mounts it should be mentioned that Coryanthes were found to grow even better on sandwich mounts without bark, only Styrofoam (make sure by calling the producer its free of Freon or similar toxic substances added to prevent fire in some kinds of styrofoam), some large pieces of broken clay pots and a bit FIBER peat fixed together with a cord made of synthetic material. -Juergen Boehm Orchids
