~POT PLANTS 
Many bulbs, corms and tubers are most desirable for growing in pots as house or 
greenhouse plants. In the following pages, hundreds of varieties are listed and full direc- 
tions are given for growing them. Many other plants like Billbergias, Anthuriums, Or- 
chids, Marantas, Maricas and African Violets are favorite house plants and are listed 
although they are not “bulbs.” We try to offer you the world’s finest plants (including 
bulbs) for growing in pots. 
CATALOG ARRANGEMENT 
is by Plant Families, according to their relationship. 
In the following lists the genus (plu. genera) is mentioned first. After it, the species 
(plu. also species) or horticultural variety is named. The initial of the genus is used for 
the second and succeeding species. Thus A. will stand for Amaryllis or Agapanthus de- 
pending on the genus last named in full. When a person’s name in parentheses follows 
a plant’s name, that person is the botanical authority for the name. 
THE AMARYLLIS FAMILY — Amaryllidaceae 
This Family includes the following bulbs, Agapanthus thru The Alliae. 
The American Plant Life Society was founded in 1934 as The American Amaryllis 
Society, which still carries on as an integral branch of the larger society. The interests 
of the society now include other bulbs and plants. There is no lessening in the interest 
paid to Amaryllids. 
The annual book, “Herbertia,” is devoted to Amaryllids. It consists of 135 or more 
pages, beautifully illustrated, on fine book paper, and is edited by Dr. Hamilton P. Traub 
of the U. S. Dept. of Agriculture, the greatest living authority on the Amaryllidaceae. 
Each member receives a copy. 
The members also receive the occasional publication, “Plant Life,’ on other bulbs 
and plants. As a temporary economy measure, Herbertia may be bound with Plant Life. 
Those who grow Amaryllis as an interesting and intellectual hobby and who love 
their vivid beauty, are invited to become members of the society. The annual dues are 
$3.00 per year, which you may send to Mr. E. Frederick Smith, Sec., Box 2398, Stanford, 
Calif., or you may include this membership fee with your bulb order to me. 
The Society also publishes the following books, bound in manila paper. 
Amaryllidaceae: Tribe Amarylleae, by Traub and Moldenka, 18 illustrations, 194 
pages. $4.00. This is a systematic treatment of one of the main tribes of Amaryllids, in 
scientific language. The most important work on the taxonomy of Amarylleae since the 
publication of Baker’s “The Amaryllideae,” in 1888. 
Catalog of Hemerocallis Clones, 1893—1948. The only complete work of its kind. 
100 pages. $1.50. . 
Amaryllid nomenclature. Carl Linnaeus, father of modern botany, made the first, 
rather complete scientific arrangement of plants according to relationships in the 18th 
century. His information about many plants was wholly inadequate to achieve perfection. 
Even in my later first French edition, 1798, nearly all American epiphytic orchids were
