T. o. ‘Roy Elliott Very dwarf form with spotted and unspotted leaf form. It originated from seed collected by Wayne Roderick on Cook and Green pass. Named by Kath Dryden about 25yrs ago but she lost her plants in winter 1981/2
T. o.‘Shiral’ previously‘Al Smith’ neither an official name. Full double as regular as a gardenia. Originally found by Verne Ahier on Vancouver Island (? ?) and came via John Derrick and Jack Todd to Al and Shirley Smith who propagated it. Diane Whitehead in the newsletter of the Vancouver Island Rock and Alpine Garden Society and Darcy Gunnlaugson in Trillium-L. Darcy states with him it flowers at the same time as grandiflorum.
T. o. ‘Vern Ahier’ Informal double with flattish petals , central ones slowly becoming smaller and more erect, bright red in age.
T. o. ‘Honey Suckle’ on the web page http://www.goldsword.com/sfarmer/Trillium) of Susan Farmer under the name of Jan Renfroe a photograph of this plant. Jan states discovered in the Olympia, WA area 1998. A large (19"tall) plant with 3 white petals measuring 2.5"x1.25" and very yellow long stamens with cream colored ovary and stigma. Leaves are 6"to7" across. The name comes from the intense scent of white honeysuckle.
T. o. ‘Roy Elliott’ named by Kath Dryden for a 4" plant with blotches on its leaves which may be synonymous with T. o. var. maculosum Case. Leaves blotched or spotted with dark maroon or maroon-green markings on upper surface (but not on lower). The plant of this name Potterton’s, of Lincolnshire, England, sell is a 4" tall plant which sets seed well but has plain green leaves.
T. o. ‘Rochester’ Informal double, petals size slowly decreasing and casually arranged- seems to resemble Ahiers double
T. o. ‘Saunders Creek’ Informal double, outer 3 petals inclined to be noticeably longer, inner ones short and noticeably twisted

According to P. & S, This form is dedicated to Mr. W.F.Shay of the Biology Department at Normandy High School, Missouri, who first called attention to it. Collected at Monarch Hill, near Monarch, St. Louis Co., Mo., April 29, 1935, by W.F.Shay ( Mo. Bot. Gard.)."
T. r. forma luteum Clute The petals are greeny-yellow but the claws of the petals, and the stamens brownish red. Freeman feels there are so many colour gradations to which this may be applied.
T. rivale ‘purple heart’ white petal with blotched heart shaped purple base
T. r ‘Del Norte’ a form that has glaucus leaves with very strong silver veining and good overlapping heart shaped petals. This form is understood to come from Del Norte and found by Boyd Kline. It was found by Boyd Kline and his business partner Lawrence Crocker in the mid to late 60's. There are 2 crosses/forms. The first form is T. rivale by T. ovatum and can produce very pink and very big rivales. The other form is T. ovatum by T. rivale. I have not seen this cross, but it seems that it would/could produce some interesting plants (Jan Renfroe).
T. r.’Roy Elliott’
T. r.’Verne Ahiers’ Flowers shell pink in colour, cup shaped, and flecked with purple on inside of petals. They fade to white as they age. Original plants found at Saanich, Victoria, B.C. and in 1968 moved because of development to Mr & Mrs Verne Ahiers rock garden in Victoria.
T. r.’Wayne Roderick’s form’ Largest flowers of pure white. largest form and growth robust. Paul Christian catalogue

T. r. ‘Gunnar’ after my father states Darcy Gunnlaugson. This is the rivale with the dark leaves and white veining which resembles a form of rivale called Del Norte from that county in California. The flower is white with pink spotting. Until now it has been referred to as the Del Norte form from Darcy's place, albeit it never came from Del Norte county, but rather from seed collected from a similar plant in southern Oregon.
