274 BOTANICAL GAZETTE. [Oct., 
On returning to Scotland, after this second American tour, he was in the 
year 1824 recommended by Mr. McNab, of the Edinburgh Botanical Gardens, 
to collect and take charge of a vessel load of plants to be taken to St. Peters- 
burg for the starting of a botanica! garden there, in which mission he acquit- 
ted himself to the satisfaction of his employers. On his return from this expe- 
dition he settled down with his family in the nursery business, but returned to 
Russia again in 1830 and made a collecting excursion through the country, 
amongst some of the fruits of which was the introduction to the English horti- 
cultural world of such plants as the Picea pictita, Pavenia tenuifolia plena, 
etc. From this time till the year 1844 he followed the business of nurseryman 
and florist at the old home near by to the birthplace of the poet Burns, a few 
miles from the town of Ayr 
In 1844, having formed a favorable opinion of Canada West as a place of 
emigration, in which he might have a chance to better the circumstances of 
himself and family, he took ship with his entire household, for Montreal, and 
from there journeyed westward and chose as a resting-place a spot near some 
of his old-world neighbors, about a mile from Ayr, in the county of Waterloo, 
where he died, surrounded by children, grandchildren and great-grandchildren, 
last June, in his ninety-fourth year. 
ium molle DC.—This species, heretofore accredited to Florida, 
seems to be no nearer to us than St. Thomas of West Indies, Panama, and trop- 
ical South America. It should be dropped from our catalogues. The plant 
escribed under that name with doubt by Chapman, and on that authority en- 
tered in Watson’s Index, is D. tortuosum DC. To it are to be referred No. 30 
Garber’s South Florida Fl, and No. 623 Curtiss’ N. Am. Pl. Its more distant 
verticels of filiform, recurved, thrice longer (9’) pedicels, and its pendulous 
loments of 4-6 equal, twisted, 2’ long, fertile joints, sufficiently distinguish 
- tortuosum from the following : 
D, molle DC.; ? Macf. Fl. Jam.; Benth. in Fl. Brasil; Griseb. Fl. Brit. W- 
Ind. ; not Chapm. (No. 861 Eggers’ Fl. Ind. Oce.)—Probably distinct from every 
other known species by its loment. This is 2- or occasionally 3-jointed ; up- 
per joint only perfecting seed, flat, oval,enlarged (3 long) and detaching itself 
at maturity, suture notched at insertion of seed ; lower joints minute, undulate- 
twisted, sterile, persistent.—Joun DonNELL SmivH, 
of several leguminous seeds, published in the Bulletin of the Torrey Botanical Club, 
February, 1886, at Dr. Coulter’s suggestion I made an examination of the 
testa of the seeds of Phytolacca, with the following results: There are four 
distinct regions: 1, The palisade layer (I). This layer consists of flat very 
thick-walled cells, each containing a very irregular cell cavity, completely 
filled with a large granular mass and numerous small granules. The thick 
walls contain a brown pigment, and are roughened all over by small projec-
