CustomOrechidSubtile.java:353 currently says

tooltip.add(TextFormatting.BLUE + I18n.translateToLocal("botania.flowerType.special"));

The string "botania.flowerType.special" has no definition in the Botania lang file. Either add a localization for it or do what I think you probably meant to do and use "botania.flowerType.misc" instead.

Actually, only the Pure Daisy and Manastar are "Miscellaneous Flower" type, so honestly I'd rather have any kind of Morechid called a Functional Flower regardless of its mana cost.
