Observations
 
      Flowering is variable, with a peak at the end of spring.
      All the floral parts are whitish with clear pink suffusion, more or less stripped with purple. Lateral lobes white , with small orange spots at base and 3 mauve lines on the top. Midlobe provided with 5 to 7 longitudinal strippes, radiant, pink darker then browning to the base.

     Different from Phalaenopsis equestris by the marblings of the foliage, the green stalk, and the orbicular and apiculate midlobe.
     It is growing to an altitude of 1500 meters, which makes of it a moderate hothouse plant which asks for a temperature of 22/24C the day and 11/14C the night.
      In a traditional greenhouse with Phalaenopsis, it can profit from a greater comfort if it is cultivated in clay pot, which ensures a greater freshness at the level of the roots.
 
Historique
 
      Phalaenopsis lindenii was collected and described by Loher in the «journal des Orchidées». It was named in honor of Jean Jules Linden (1817-1898) Belgian horticulturist.
     It was suggested that Phalaenopsis lindenii could be a natural hybrid between Phalaenopsis equestris and Phalaenopsis schilleriana. This assumption remained without continuation.
       Some additional words from Rolf in the Orchid Review N°152 august 1905 and in october 1907.
