This is quite tall, the slender, rather weak stems being sometimes over a foot high, with smooth leaves, often with some hairs on the veins of the under side. The flowers, over half an inch across, with a short petal-spur, are almost white, delicately veined with purple, yellow in the throat and tinged with violet or purple on the outside. Occasionally they are pure-white all over and sometimes sweet-scented. The capsule is oval and smooth. This is common in eastern mountain woods, and to eastern eyes looked far from home when we found it in Walnut Canyon in Arizona.
