Lately a few rosarians have become fond of stating that other Chinese roses were brought to Europe around the same time as 'Old Blush', 'Slater's Crimson', 'Hume's Blush', and 'Park's Yellow tea-scented China.

I am looking for sources that suggest or reveal that there were more than these Four Studs mentioned by Hurst which initiated the hybridizing of remontant roses. H.C. Andrews of 1805 is one such source, and I've recently located a number of sources re: Park's Yellow and other early yellow chinas.

Does anyone know of other sources that address the earliest pink or red chinas/teas?
