ELEGANS (Rose, 1905), E. Cent. Mex. state of Hidalgo (& most adjoining states) in mtns., name means “elegant”, Walther series 2, #15, p.97, (fig. 39, p.98), see p. 80 in Haseltonia #4, 1996 for Uhl’s discussion, old Series 2, later in revised Series Urceolatae, but now in new Series 16, (Urbiniae) in 2003 Lexicon; cytology: n=31, 32, 34, 60, 62-63, 96, 120-130. Plants have little main stem, rosettes branch freely, leaves in lovely and dense rosettes of greenish-glaucous, to white color. Inflorescences are a cincinnus 10 to 15 cm tall, flowers are rose to pink shading to yellow-green at apex. This species has long been one of the most popular with collectors and in nurseries and gardens. It is a bit more frost sensitive than most. It is a bit variable in nature, and collected extreme forms were published as full species or as varieties (see below), but these were too weak botanically to stand, so were combined by Kimnach in 2003 Lexicon.
