Discovery of Tacitus bellus by Alfred Lau
艾尔弗雷德先生发现
美丽莲
"This plant I discovered years ago and I brought it home thinking it might have been a Graptopetalum; potted it and put it to one side and temporarily forgot about it, until one day my son Alfred asked me to come to the greenhouse to see the lovely flower; when I got there I found that it was not a Graptopetalum but a new plant altogether.
"这是我多年前就发现的，我把它带回家并认为是风车草；盆栽放在一边，暂时忘记了它，直到有一天，我的儿子艾尔弗雷德要我到温室去看可爱的花；我到那儿时，我发现这不是一个
风车草属，是一种全新的植物。
A little later, I took it to Mexico City to Dr. Bravo at the University there. She was so excited about it that she immediately phoned Dr. Meyrán asking him to come as soon as possible with his best camera. Later it was published under its present name Tacitus bellus, and has been called the succulent of the seventies, and my first plant discovery.
一段时间以后，我就去墨西哥市的大学找到布拉沃博士。她对此十分激动以至于她马上打电话给Meyrán博士并要他尽快带着他最好的相机来。后来它改名为Tacitus bellus发布，被称作是七十年代的
多肉，我第一个发现的植物。
It came out on several calendars and is used in Germany as a Mothers' Day plant. It is very easy to propagate and each leaf, when detached, produces 1-2 or even 3 new plants. When I found it in 1972 I brought back 3 plants and now there are millions in the world."
它被印在几个日历上并在德国作为一种母亲节用花。它非常容易通过每一片叶子繁殖，当叶片与母体分离后会产生1-2个甚至3个新植株。
我1972年发现并带回的3棵现在在全世界已经有数以百万计的种苗。"
This was a part of A. Lau's talk at the Convention CSS in Melbourne in June 1982,published in 'The Spine' Vol. 30 No. 3 June 1982.
这是A. Lau与 1982年六月在墨尔本公约CSS讲话的一部分，于1982年六月发表在'The Spine'30卷3号。
Note :A seedling from Tacitus bellus is wrongly called Tacitus bellus 'Superstar'. This name is not correct, because the plant is a hybrid, possibly with Graptopetalum rusbyi and therefore it has to be called xTacipetalum 'Superstar'.
注：美丽莲被错误地称为Tacitus bellus 'Superstar'。这个名称是不正确的，因为植物是一种杂交，可能与银天女有亲缘关系，因此也被称为xTacipetalum 'Superstar'.。
