1917] Goodspeed: Notes on Trillium 73 



Stevens (1894) notes the case of a flower in which ''a stamen and 

 a petal were united edge to edge, one anther cell being obliterated by 

 the union." The plant was otherwise normal. Victorin (1904) de- 

 scribes two plants apparently tetramerous throughout. In one flower 

 a petal was anther-bearing. A flower, presumably of 1\ grandiflorum, 

 is mentioned by Meehan (1894a) consisting of "eighteen beautiful 

 white petals." A normal whorl of leaves is spoken of and it is prob- 

 able that the sepals were also normal (ef. Meehan, 1894&, who describes 

 a "very perfect eighteen-petalled flower"). The rootstock apparently 

 produced abnormally flowering shoots for three years after being 

 transplanted into a garden. Peck (1888) notes two plants in which 

 "not only petals but also sepals were wholly white." 



Trillium erectum L. 



Andrews (1906) briefly mentions an abnormal individual of this 

 species, the flower of which showed flve petals, four stamens, and two 

 styles, while the outer whorls were normal. Deane (1910) notes a 

 plant with a single whorl of four leaves, five sepals partially petaloid, 

 four petals, eight stamens, one of which was double, and an eight- 

 winged ovary. Bishop (1902) refers to "a few instances where the 

 whorls are repeated but none with the lengthening of leaf and flower 

 stems" so characteristic of the extreme variations of T. gmndiflorutn. 

 Clute (1895) reports a flower of this species with four petals — each 

 edged by a pollen-bearing anther — and flve stamens. James (1884) 

 describes a teratological specimen of the following type : four sepals, 

 four petals, eight stamens, "four pistils and a four-celled ovary," 

 whorl of leaves normal, a fourth leaf on the peduncle halfway between 

 flower and leaves, and the sepals wholly or partially petaloid. 



The remainder of the pertinent references to T. erectum which 

 have been found deal with the color of the flower and especially the 

 occurrence and origin of the var. album Pursh. Gray (1908, p. 293) 

 describes the petal color of erectum as "brown-purple, or often white 

 or greenish or pinkish." Thus a considerable range of color-forms 

 seems well recognized. Hall (1870a) comments upon the occurrence 

 of the normal "purple" form associated with the less strongly pig- 

 mented forms. He says: "I have watched individual plants of this 

 variety (var. album) as closely as possible, and seen the regular purple 

 flower in their place the next year; and have also seen the var. album 

 flower in places when the year before a purple flower had ai)peared. 

 T have noticed, too. that, as a rule, the var. albu))i is a starveling:
