BOTANICAL GAZETTE. 



No. 4 is twice forked and has 3 leaves, with the flower borne in the fork between 

 the upper leaves. 



No. 5 is the same, except that the peduncle arises from one of the branches 2 or 

 more inches above the upper fork. 



No. 6 is like No. 2, but one branch is shorter and more slender, leaving a much 

 smaller leaf which is only 3-lobed, evidently a transitional state between No. 2 and the 

 next. 



No. 7 is No. 2 with one of the branches wholly suppressed, the remaining branch 

 assuming an erect position. This is the most common of the aberrant forms and is 

 more abundant than ever this j'ear. 



No. 8 is No. 2 with both branches suppressed. It might pass for a scape, were not 

 the stem just as thick and the peduncle as slender as usual. 



No. 4 and 5 furnish good and well marked examples of acceleration in develop- 

 ment, and Nos. 6, 7 and 8, of retardation, both occurring in the same species and in the 

 same place. 



In the last edition of his Manual, Dr. Gray states that Podophyllum peltdtiini has 

 been found with several carpels, instead ol oiie, and I may add that two sucli instances 

 have fallen under my observation. — Thos. C. Porter, Eastou, Peini. 



Some N»tes on Nepeta Glechoma and Other Pl.vnts. — I have just returned 



from a second short visit to Pulaski Co., Virginia. ILilesia tetraptera was just coming 



into bloom (April 26), Draba veriui fully expanded, and Se/luni Nevli not yet in flower- 



In Pulaski, Draper's Valley, I again examined Nepeta (May 18) Tlie plants yri</t 



crosses have increased in numbers, speading up the hill from tlio spot where they were 



at first confined to a space of a few yards. I send you the following measurements: 



With Crosses. I Without Crosses- 

 Greatest icidth of flower 7-16 \ 4-16 



Extreme length of flower 14-16 ! 6-l(ito8-16 



Extreme length of calyx 



Size of crosses, i.e. length of arms . 



Clear length of the corolla.

14-16 



Tul)e 9-16 



i 5-16 End of Tube to dilatation. 

 I 4. 



16 Dilated part of tube. 



Lobes 5-16 

 Larger flower irith crosses. — 



Corolla tube much dilated, hairy, mot- 

 tled with purple spots, imitating very 

 much Physostegia Virgimana; throat 

 (lower lobe of corolla) beset with thick 

 white hairs or glands 1-16 inch in length ; 

 stem square, the edges bristly downwards. 

 Calyx 16-ribbed,bristly. Pistil closely set 

 ill the groove of the upper lip. Upper 

 anthers (cross) just below summit of up- 

 per lobe, say 1-32 inch below ; lower an- 

 thers (cross) white or reddish!, just at sum- 

 mitof undivided tube, t. e. at base of upper 

 lobe. 1-16 inch of fiower crserted from 

 calyx. 



Color pink, or light-reddish purple. 



Smaller flower icithont crosses. — 

 Corolla tube slightly, if at all, dilated, 

 closely hairy with small hairs. 



Hairs delicate, 1-32 inch in length. 



Bifurcated pistil sheering off from upper 

 lip of corolla. Upper anthers (no cross) 

 below the top of undivided tube, lower 

 ones 1-32 inch below the ui)per. 



Corolla and raly.r together less than 8-16 

 inch. 



Color d^rk-hluish purple, or rather pur- 

 plish blue, often called b}' persons a blue 

 flower. 



Both plants were maturing from one to four seeds; one seed, frequently, much lar- 

 ger than the others. At Mr. Draper's the two plants were at times intermingled, but
