A very good description of the specie in: "Wetland Plants of Southwestern United States" by Donovan S.Correl – Southern Metodist University and Helen B.Correl – Botanical Editor and Researcher for Environmental Protection Agency, 1972, on page 1315

I quote this description

[i]" Erect annual to 5 dm. tall, usually much smaller; stem with few or no branches on lower half but with several simple or forking mostly alternate branches above; leaves membranous, oblong-elliptic to broadly ovate-elliptic, obtuse to acute,
broadly clasping stem, to 45 mm. long and 2 cm. wide; calyx tube to 8 mm. long, strongly pentagonal with 5 short wing-angles extending up to the sinuses, its 3-nerved lobes linear-lanceolate and to 25 mm. long; corolla roseate to pale-pink or
rarely white; corolla lobes broadly obovate to elliptic, obtuse to acute, to 23 mm. long and 15 mm. wide, their yellow basal spots 3- to 6-lobed with 1 or 2 middle lobes longest; stigmatic lobes greenish, becoming yellow with age, 5-8 mm. long;
capsule to 9 mm. long. " [i]

Here I found the book (opened to the page where I extract the quote) http://www.biodiversitylibrary...

Year of the book is 1972. For not be in copyright the book must be older like 70 years, that means must be publicated prior of 1923.

But how I can see here http://www.biodiversitylibrary... -

if I "Exapand All Scan Details" and If I well interpreted, the book is not in copyright.
I hope I don't broke some rule about quoting. If it is so I please to moderators to take corection. (In Roumania it is permited short quoted - mentioning the book and authors-, but I don't know the rules about quote in U.S.)
