     For those who are interested, here is what I have on heat tolerant 
lilies, unfortunately without any suggestions of sources:

Heat tolerant Lilies

L. alexandrae-Ryukuyus and a few other islands in southern Japan. 1-3' 
tall.  Flower pure white, trumpet
     shaped,     carried horizontally or slightly raised.  Wants to grow 
steadily during winter.
     Has been hybridized with speciosum (Ruth Clas, Easter Bunny) 
(Judith Freeman in early 1970's
     with speciosum 'Shooting Star') and many more.  Other hybrids with 
rubellum, nobilissimum, and
     'Little Rascal'.  Succeeding generations were very fertile.

L. brownii, brownii australe

L. bakerianum

L. catesbaei--Florida swamp lily

L. formosanum (from Formosa, now Taiwan)   From sea level, a variety 
called "Wilsonii" to seven (10') feet and flowering late, an 
intermediate altitude,  medium  tall variety that flowers later, and  a 
short variety from high altitudes called pricei 1-2', July,

L. iridollae-Florida, etc USA-rare and probably not in commerce.

L. longiflorum-Easter Lily-but, there are tall ones, short ones, 
diploids, tetraploids, earlier and later
      L. longiflorum and its near hybrids are widely grown commercially 
in subtropical climates--
     Bermuda for instance was at one time the source of bulbs for the 
american forcing market.

L. nepalense

L. neilgherrense-from India, grows further south than any other lily?

L. nobilissimum  Ryukyu islands, Japan-upright to 3-4', with up to six 
pure white upright flowers on short
         stalks, to six in number.  Seed germination is dalayed 
hypogeal.  Very late flowering
         Native to cliffs, requires extreme drainage, very susceptible 
to Fusarium.
         Has been hybridizerd with alexandrae, auratum, speciosum, Pink 
Glory Str, Imperial
         Silver strain.  Some hybrids are triploids, some diploids
     Taj Mahal is a hybrid of nobilissimum currently being offered by 
The Lily Garden

L. michauxii, Carolina Lily.  Native to Virginia to Florida to Alabama 
and Louisiana.

L. philippinense-from Luzon province in the Philippines.  Grows close to 
the sixteenth parallel.  Flowers
     in July or August, to 3' tall.  Close to formosanum.

L. primulinum

L. sulfureum

L. wallichianum    (beware this name in seedlists, it often disguises L. 
formosanum or something else)

     In Growing Lilies, by Derek Fox , p40 the list recommended for 
growing under glass:
     arboricola  (this lily probably not in cultivation)
     bakerianum (stoloniform bulb)
     brownii australe
     neilgherrense (stoloniform bulb)
     nepalense (stoloniform bulb)
     primulinum (stoloniform bulb)
     wallichianum (stoloniform bulb)

     There are a number of lilies coming out of China now which may well 
be tolerant of higher  temperatures.
     They are new and not being widely distributed yet, and which 
species, and details of cultivation are limited.

     nobilissimum hybrids such as Taj Mahal

     L. parryii is native, among other places, on Mount Lemon in 
Arizona, at high altitudes.

     At one time a member of the lily society grew lilies--mostly 
trumpet hybrids--in Texas.

     At one time a lily society member writing from South Africa 
reported that L. philipinense had become a weed in both Africa and
