Oh tea itself can have up to 100mg of caffeine per serving itself, if not somewhat less or more, depending on variety and steeping.
Tea doesn't just contain caffeine, it also contains small amounts of the drug theophylline, first extracted from tea leaves and eventually synthesized.
Its an agent used in certain asthmatic disorders but is pretty potent and full of side effects and isn't used for many these days.
Most varieties of tea, fermented Camellia sinensis probably have an average amount of caffeine but Black Tea has the most, with varieties of Green Tea generally having smaller amounts of caffeine.
