With respect to cold temperate plants in Madeira, I, of course, know not enough to form an opinion; but, admitting Atlantis, I can see their rarity is a great difficulty; otherwise, seeing that the latitude is only a little north of the Persian Gulf, and seeing the long sea-transport for seeds, the rarity of northern plants does not seem to me difficult. The immigration may have been from a southerly direction, and it seems that some few African as well as coldish plants are common to the mountains to the south.英文原著 · 《More Letters of Charles Darwin Volume I》
The only thing that saves the race from ruin through passion is the rarity of those by nature or by art expert in using it.

Norman felt that destiny had suddenly revealed its resolve to destroy him by giving him not one of the things he wanted, but all.英文原著 · 《The Dust》
There is a favourable, but not strong enough review on you, in the "Gardeners' Chronicle". I am sorry to see that Lindley abides by the carbonic acid gas theory.

To my mind, putting the comparative rarity of existing species in the same category with extinction has removed a great weight; though of course it does not explain anything, it shows that until we can explain comparative rarity, we ought not to feel any surprise at not explaining extinction...英文原著 · 《The Life and Letters-1》
Among her pupils are two fine voices--Tom Wilder, a grand bass, and the rosy-cheeked curate, a greater rarity still, a genuine counter-tenor.英文原著 · 《A Woman-Hater》

(1) Mimicry may occasionally arise in one sex because the differences which distinguish it from the other sex happen to be such as to afford a starting-point for the resemblance. Here the male is at no disadvantage as compared with the female, and the rarity of mimicry in the male alone (e.g. Cethosia) is evidence that the great predominance of female mimicry is not to be thus explained.英文原著 · 《Darwin and Modern Science》
