[Alister Clark used R. gigantea as one of the parents in his breeding program] He believed that this rose's great vigour was an essential attribute to pass on to his hybrids.

The ancestor that gave to the Tea roses their special character. This glossy-leaved species clambers vigorously through other plants in its natural environment … The flowers of R. gigantea are white, five-petalled, opening the size of your palm; but in the bud, before they open, they have the most exquisite form, high pointed and slender, a shape that future generations would value above all others.

R. gigantea Collett ex Crép.
synonyms: R. odorata var. gigantea (Crép.) Rehd. & Wils.;R. macrocarpa Watt ex Crép.; R. xanthocarpa Watt ex Baker [The follow excerpt shows why this book is such an invaluable reference for students of species roses]
A native of N.E. India, Upper Burma and Yunnan; discovered by Sir George Watt in Manipur in 1882 but described in 1888 from specimens collected by Sir Henry Collett in the Shan Hills of Upper Burma...and introduced by him (the seeds were distributed from the Calcutta Botanic Garden in 1889).
The largest flowered of all wild roses...R. gigantea was reintroduced by Frank Kingdon Ward in 1948 from Manipur, where he found it flowering....(Plant Hunter In Manipur (1952), pp. 45-6). The largest plants he saw had stems 'as thick as a man's forearm', but the original specimen at the Château Eléonore attained a girth of almost 5 ft at the base before it died.
R. gigantea, in its typical state, extends into the southern parts of the Chinese province of Yunnan. But of greater interest are the forms collected by Forrest in central and norther-western Yunnan, which are of smaller stature than R. gigantea of Burma, even shrubs no more than 5 ft high, with fragrant flowers in shades of pale yellow or rose....It is perhaps these Yunnan forms, which Forrest found both wild and cultivated, that gave rise to the tea-scented roses of Chinese gardens....

p. 97: Hybrids of R. gigantea: aside from the work of Paul Nabonnand, Father Schoener, Alister Clark, and Captain Thomas, very little has been done in this field. The botanical species, R. gigantea, is reputed to have been discovered in Burma in 1887, but, in reality, Gilbert Nabonnand was already growing R. gigantea at Golfe Juan about 1875... The first hybrids, one of which was 'Etoile de Portugal', were obtained in 1898 at the Botanic Garden of Lisbon, by Henri Cayeux, now Director of Gardens and Walks at Havre...
p. 98: Although not remontant, the hybrids of climbing Giganteas have another great advantage -- they bloom ahead of other roses, even Teas. Besides, their vigorous growth covers a large surface quickly. The botanic type easily reaches a height of sixty feet, and hybrids ten years old cover a surface one hundred and fifty feet square, so they are not suitable for small rose gardens...

Rosa Odorata Gigantea. Rehder. Probably the ancestor of the Hybrid Giganteas...It is all mixed up with species like R. macrocarpa, R. xanthocarpa, and R. gigantea. Nobody knows what the difference between these varities is except the botanists, and they successfully keep the information to themselves by hiding it in a mass of technical language.

Rosa Gigantea And Its Hybrids by H. Cayeux
Henri Cayeux describes how Rosa gigantea bloomed in Europe for the first time in April 1896 in the Lisbon Botanical Garden. Cayeux recommends grafting a flowering branch to Rosa indica to obtain flowering much earlier than from plants grown from seed, which grow so vigorously, up to 8 to 10 meters a year, that they flower very little. He also reports even more generous bloom by top grafting Rosa gigantea on Tea roses that have been grafted on Eglantine, thus allowing hybridizing without using a ladder.

Yunnan: Lichiang valley, alt. 2500 m., May 1906, G. Forrest (No. 2049); Tali valley, alt. 2000-2400 m., May 1906, G. Forrest (No. 4452).
This form differs from [Rosa odorata var. gigantea] in its pale pink often somewhat smaller flowers.

Rosa odorata var. gigantea Rehder & Wilson
This variety is the wild form of the Tea Rose; it is widely dispersed in Southern Yunnan and has been reported from Mengtsze in the east to the frontiers of the Shan States in the extreme southwest. The flowers vary from white to yellow or pale buff or to pale pink and are delightfully fragrant. In tall thickets and margins of woods it is a tall and rampant climber, but on the open plateaus it forms a bush with arching stems and is often not more than 2 m. tall.
