glaucous green above, and a reddish glaucous green below. The 

 stalks are reddish. It is invariably found in the deepest shade of 

 underbrush, and usually growing up through dead brush. As it is 

 exceedingly brittle, a strong puff of wind being sufficient to break off 

 the tips when entangled, this habit of growing in brush makes it 

 exceedingly difficult to secure entire specimens. I have been unable 

 to secure more than one frond out of three in a presentable condition. 

 It fruits during the middle of October, the fruit forming a deep black 

 margin to the lightish colored segments. — Henry H. Rusby. 



On the Colors of some Western Flowers.— There are a 



good many mistakes about them in the books Cordylanthus Wrightii, 

 Gray, for example, is everywhere described as having a purplish cor- 

 olla, whereas it is of a fine, light-sulphur yellow, which stands in showy 

 contrast with the commonly rich, dark purple calyx which half 

 encloses it. 



OrtJwcarpus purpureo alhus. Gray, is said to have corollas "purple 

 and often partly white ;" the truth being that they are always clear 

 white oil opening, and that after the first day they change to rose- 

 purple. 



In the January Gazette under Ribcs pinetorum, Greene, I said 

 that the flowers of ^. leptanthum, Gray, are "white, not yellow, as said 

 by Mr. Watson in Bot. King." But Mr. Watson writes to me that 

 he has seen acres of it with yellow flowers. Now though the species 

 occurs plentifully west of the Rocky Mountains I do not happen to 

 have met with it but in Colorado and New Mexico, the locality 

 whence it was first obtained, and I have never seen it but with white 

 flowers, though there is usually a tip, or marking of decided green. 

 The dubious var. brackyaiithum, Gray, of (California shows a tinge of 

 purple. Will not our botanists in different parts of our western field 

 take notice, the coming season, and all tell us through the Gazette 

 what they find to be the color of flowers in R. leptanthum ? Of course 

 they may vary in different localities, but if this be the case, it should 

 be established clearly.— Edward Lee Greene. 



Carnivorons Plants. IV.— Experiment No. IX.— Placed upon 

 the center of the disk of a very vigorous and large leaf a small crumb 

 of bread made from wheat flour, at 2:45 p. m., June 11, '79. 

 30 min. a few of the submarginal tentacles had bent slightly. 

 90 " these tentacles were standing about at right angles with the 

 plane of the surface o{ the blade of the leaf. 



3 hrs. many of the marginal tentacles had moved some. 

 7 "a few of the submarginal tentacles were so inflected as to 

 touch the specimen ; also the marginal were much inflected. 

 10 " but little changed from the last note. 



17 " all of the submarginal, marginal and outer disk tentacles had 



inflected to such a degree that nearly all of them touched 



the specimen ; the edges of the leaf were also incurved 



greatly. 



24 " leaf completely closed ; substance of the bread soft and pulpy.
