Cathaya Argyrophylla is one and only specie of its genius. Dawn Redwood was once thought distinct. Again, the only one of its genius. Its tiny leaves doesn't look like needles from afar. Taiwania Coffin Tree has very prickly needles. Umbrella Pine's long needles are not leaves, but stems. 
China Fir (a cypress) has rare proliferous seed cones, where the stem will continue to grow through. The Stinking Cedar (a yew) has a pleasant citrus smell.The rest of the tour is the same as last October. Good to refresh my memory.
I caught a shuttle down to Vietnam Memorial and walked to downtown.
