论文名字叫做：E. Cante（广寒宫），一种来自ZACATECAS山的新品种
论文发表于1997年，这个时间也是Cante这个名字第一次写入多肉的植物学命名中，并且沿用至今。但是相对奇怪的，广寒宫这个物种却很早就在多肉养殖行业中存在，并且存在了很长的时间。但是正式命名确是在很多年后，这期间有部分原因存在。

论文摘要：
在研究了一些来自墨西哥中部的五个州的九个地方的Echeveria subrigida（刚叶莲），部分Echeveria Gibbiflorae（粉彩莲），发现一部分来自Zacatecas西北部的人群把其与这两个物种混淆了。来自前九个地区的植物样品与圣路易斯波托西州典型的刚叶莲无差异，包括描述为E. palmeri的样品。然而，来自萨卡特卡斯的植物是一种新的未描述的物种，我们以Canche，A.C.的名字命名为Echeveria cante Glass＆Mendoza（Glass和Mendoza为命名人）。它不同于刚叶莲，它拥有的大量的白色被粉而不像刚叶莲叶片上苍白的少量粉霜，它们叶片比刚叶莲的更窄，更厚，通常更长，在比较中在花上还存在各种差异。
其中我要解释几点
1.Echeveria cante Glass＆Mendoza中，最后的Glass＆Mendoza表示命名人
2.当时人们眼中的广寒宫被命名为刚叶莲，并且在当时西方养殖行业也广泛运用，但其实和真正的刚叶莲是有区别的。

论文正文第一段：
至少在过去的半个世纪里，一个名为“Echeveria subrigida”的植物在美国和英格兰都成为成功赢家。1969年11月，Glass在离开墨西哥城的Bob Foster机场后，花费大量时间悠闲地攀登从萨卡特卡斯市到杜兰戈市的山脉，在他看来这是找到新的或有趣的植物材料的最佳途径。在Sierra de Chapultepec北部（北回归线附近的塞普尔特佩克），他偶然发现了一丛靠近崎岖山峰的植物，它看起来非常美丽，令人叹为观止。它看起来像仙女杯属中的D. pulverulenta（雪山）或D. brittonii（布瑞冬尼），但这些仙女杯不可能出现在这些山中。他认为这株植物一定是之前在加利福尼亚州看过的刚叶莲。他收集植株标本并且标记下了标号Gl. & F. 1676.他于1970年5月再次返回当地，此次他们收集了更多的材料，编号为Gl. & F. 2645。
此时的植物界，错误地将广寒宫当作刚叶莲来养殖。
同时附上D. pulverulenta（雪山）

D. brittonii（布瑞冬尼）

直到1972年2月，他才真正在墨西哥州的野外，Tultenango峡谷地区看到了真正的刚叶莲，并且认识到野外的刚叶莲与那些年在培养植株中到的差异！伴随着Mammillaria pringlei（朝日丸，一种仙人球）在野外的惊人呈现，在Tultenango峡谷中，刚叶莲生长在铁轨上方众多悬崖峭壁上。由于当时没有对景天科进行分类学分类，所以他没有对他们进行系统的重新分类。John Pilbeam在我们墨西哥之行的记录本上阅读了我们记录的资料，并声称他亲眼看到我们记录的植物高达两英寸。他随后在他的文章“真正的Echeveria subrigida请站出来好吗？”（1991）中提出了关于这种错误认识的疑惑。
注：在1972年，有人开始提出，当时植物界命名为刚叶莲的植物并不是真正的刚叶莲，因为在刚叶莲真正原产地的形态和当时在欧洲种植的形态并不相同。

正如里德莫兰所指出的那样，“虽然瓦尔特将刚叶莲描述为明显的白色粉霜，并通过它的银叶来同E. palmeri区分，但事实上，当地的刚叶莲比他描述的植物更加的绿。我们将更近一步的提出，典型的野外真实刚叶莲不像描述的那样，是高度白色的，并且可以猜到，瓦尔特被来自Zacatecas的假的刚叶莲混淆了典型刚叶莲的一些特征，并做出了错误的描述。在1957年，旧金山斯特林植物园主任Eric Walther去世。

在二十世纪六十年代，Glass和Foster在斯特林植物园作为评委参加了一项展览，他们将一等奖颁给了一个名为E. subrigida（刚叶莲）的宏伟植物，这毫无疑问是我们现在描述为E. cante的植物。旧金山仙人掌和多肉协会的成员们相当吃惊地发现, 一种 "如此普通、容易生长" 的植物被授予如此高的荣誉，这意味着在瓦尔特时期, 这种形式的植物就已经存在, 所以他必须去了解它。Myron Kimnach也证实了这一点，他在20世纪50年代在伯克利植物园向我说，他在加利福尼亚大学植物园工作期间也培养了我们命名为广寒宫的植物，当时被称为作为刚叶莲，然而真正的刚叶莲当时并未在海湾地区种植。

1991年，在来墨西哥生活并与Cante,A.C.组织合作后，Glass决定他需要用一种非常壮观美丽的植物来纪念这个组织，因为这个组织在墨西哥做了很多植物学和园艺学方面的贡献。由于这几十年间没有人对广寒宫进行真实的命名，所以他选择了这种精致植物作作为代表，他同时邀请了同事Mario MendozaGarcía帮助他进行这一命名。我们选择Cante作为广寒宫的种名，这是一个Pame-Chichimeca语词，意思是“生命之水”。

ECHEVERIA CANTE, A NEW SPECIES FROM THE MOUNTAINS OF ZACATECAS

Summary. Forms of Echeveria subrigida (Crassulaceae), section Gibbiflorae, are studied from nine localities in five states of central Mexico, as well as a population from northwestern Zacatecas which has been confused with that species.The plant material from the first nine localities is indistingui****le from typical E. subrigida, including the form described as E. palmeri, from the state of San Luis Potosí. It is concluded, however, that the plant from Zacatecas is a new, undescribed species which we are naming in honor of Cante, A.C., as Echeveria cante Glass & Mendoza. It differs from E. subrigida in its greater number of farinose rather than glaucous to pruinose leaves, which are narrower and thicker as well as generally longer than those of E. subrigida. There are also various floral differences noted under "Comparison".
A plant labeled "Echeveria subrigida" has been a show winner, both in the States and in England, for at least the last half century. In November of 1969, after leaving Bob Foster at the airport in Mexico City, Glass leisurely made his way up from Zacatecas City to Durango City, spending much time just climbing over the hills, the best way to find new or interesting material. In the Sierra de Chapultepec, near the Tropic of Cancer in northern Zacatecas, he came across a plant near the craggy peaks that was so breath-takingly beautiful that at seeing it he gave out a loud gasp. It looked like a Dudleya species of the type of D. pulverulenta or D. brittonii, but of course they wouldn't be here in these mountains. He assumed it must be the Echeveria subrigida he had seen in shows back in California. He collected material under their number, Gl. & F. 1676. He returned again the next year, in May of 1970, this time with Bob, and they collected more material under the number, Gl. & F. 2645.
It was not until February of 1972 that he actually saw true Echeveria subrigida in the wild, at the type locality, Tultenango Canyon, in the state of Mexico, and realized how different it was from what was generally seen in cultivation in those years and from his numbers, Gl. & F. 1676 and 2645! At Tultenango Canyon it grows on the cliffs cut above the railroad tracks in considerable quantities, along with an exceedingly impressive display of Mammillaria pringlei. Not being involved taxonomically with Crassulaceae at the time, he did nothing about the new taxon. John Pilbeam read our articles in our Mexico logbook and claims that his eyebrows shot up a full two inches on seeing our color plate of the false E. subrigida and picture of the true E. subrigida from the type locality. He subsequently wrote (1991) about the apparent confusion with this misidentification in his article, "Will the real Echeveria subrigida please stand up?".
As Reid Moran notes, "Although Walther described E. subrigida as strikingly white-pruinose and distinguished it from E. palmeri by its silver foliage, the fact is that plants at the type locality (of E. subrigida) are much greener than this and that this is a most extreme form" (pers. com). We would go further than this and state that plants at the type locality of E. subrigida are scarcely more than highly glaucous and enter the realm of conjecture by imagining that Walther was confusing the misidentified, "false subrigida" from Zacatecas with typical E. subrigida. Indeed, Eric Walther, Director of the Strybing Arboretum in San Francisco until 1957, died in 1959; in the 1960s, Glass and Foster judged a show at the Strybing Arboretum in which they awarded first prize as "Best in Show" to a magnificent plant labelled E. subrigida that was unquestionably the entity we are now describing as E. cante. Members of the San Francisco Cactus & Succulent Society were quite taken aback that a plant "so common and easy to grow" was awarded so high an honor—which implies that this form had been around during Walther's day and that he had to have been familiar with it. This has been confirmed by Myron Kimnach, who stated to me (pers. comm.) that back in the 1950s in Berkeley, at the Botanic Garden of the University of California where he worked, he grew the plant we are naming E. cante as "E subrigida" and that the true E. subrigida was not in cultivation in the Bay Area at the time.
In 1991, after coming to Mexico to live and to work with Cante, A.C., Glass decided that he needed a really spectacularly beautiful plant to name in honor of that wonderful organization, which is doing so much botanically and horticulturally for Mexico, and since no one had described it in the intervening decades, he chose this exquisite Zacatecas plant for that honor, inviting his associate, Mario Mendoza García, to assist him in that description. We chose to use as the epithet the name "cante" as a noun in aposition. "Cante" is a Pame-Chichimeca word meaning "the water that gives life".
