YELLOW AND YELLOWISH FLOWERS 
Spotted Jewelweed (Impaiiens biflora). Touch-me-not 
family. June to September. 
A widely branching annual, two to several feet high. The 
loosely clustered flowers are three-foiulhs inch or more long. 
Calyx and corolla orange with brownish spots, sepals apparently 
four, two greenish, one a pouch ; petals two, unequally two-lobed; 
spur bent back, one-third the length of the flower. Leaves egg- 
shaped to oval, coarsely toothed, with stalks. Common in damp, 
shady places and about old buildings. Pale Jewelweed {Im- 
patiens pallida) is similar but its flowers are pale-yellow and only 
slightly dotted; spur quite short. More common northward. 
Named from the fact that the seed-vessel springs open to dis- 
charge the seeds. 
Cypress Spurge {Euphorbia Cyparissias). Spurge family. 
May to September, 
A perennial herb (named for the physician Euphorbus) , gen- 
erally under a foot high. The densely crowded, stiffly upright 
stems bear at the top umbels of tiny flowers subtended by the 
yellowish bracts which give them color. The flower has a some- 
what top-shaped involucre with four crescent-shaped appen- 
dages (glands) and the three-celled ovary protrudes, with its 
three styles, each forked at the end. The leaves are narrow, 
alternate below, whorled under the umbels. The plants are 
noticeable from their manner of massing by the roadside, where 
they convey the impression of having walked out in a body from 
some neighboring graveyard.
