The first of six buds on Cereus McDonaldii flowered on the 6th of June with Mr. Macaulay, Ellsworth, Kansas, and about the same time one was opening with Mr. Pfifer, of Danville, Virginia. The simultanity of flowering in Cactaceous plants has always seemed surprising to the writer of this. Of several plants of Echinocactus multiplex, a very common kind with beautiful rosy trumpet-like flowers, all opened their blossoms the same day in a German-town collection.

"W. P.," Oswego, N. Y., says: " Last spring in looking over back numbers of the Gardeners' Monthly, I noticed different notes on time of blooming of night-blooming Cereus, and as we have two large plants, I thought I would take note of their time of blooming. The one has long, rope-like, square stems about twenty feet long - C. grandiflora; the other has flat stems - C. latifrons. The plant is about twelve feet high and from four to six feet across. C. grandiflora had twenty-eight flowers, which opened as follows: one on July 3d, nine on roth, four on 20th, three on 22d, one on 23d, eight on 27th, one on August 1st, one on 15th. The flowers slightly fragrant. The C. latifrons had twenty-two flowers on the first time it bloomed, which opened: eleven on June 18th, seven on 19th, two on 20th, the other two, two weeks later. Then it showed another batch of forty-one flowers, which opened: five on July 30th, thirty-three on 31st, three on August 1st. And now I can count about forty buds, making the third batch this summer.

Does this variety usually do so ? This variety very fragrant.
