MILLER: THE PROPAGATION OF MEDICINAL PLANTS 107 
I 
From commercial samples and shipments of crude drugs in 
which the aerial parts of the plants are used, germinable seeds are 
often obtainable. Many lots of drugs must be examined, how- 
ever, and large numbers of questionable seeds examined and 
tested. In addition to furnishing material for planting, this 
procedure also serves as a valuable means of accurately identifying 
some crude drug of questionable origin. The age of seed from this 
source is always unknown and considerable time must be allowed 
for possible failures in germination. Among the forms of which 
seed may be obtained in this manner are American wormseed 
(Chenopodium ambrosioides), angelica (Angelica atropurpurea), 
anise (Pimpinella Anisum), arnica (Arnica montana), belladonna 
(Atropa Belladonna), broom tops (Cytisus scoparius), buchu 
(Barosma betulina), cannabis indica (Cannabis sativa), capsicum 
(Capsicum fastigiatum), caraway (Carum Carvi), cardamom (E£let- 
taria Cardamomum), castor bean (Ricinus communis), celery seed ° 
(Apium graveolens), cevadilla (Schoenocaulon officinale), coca (Ery- 
throxylum Coca), colchicum (Colchicum autumnale), colocynth 
(Citrullus Colocynthis), conium (Conium maculatum), coriander 
(Coriandrum sativum), fennel (Foeniculum vulgare), goats’ rue 
(Galega officinalis), grains of paradise (Amomum Melegueta), 
henbane (Hyoscyamus niger), jumbul seed (Abrus precatorius), 
larkspur (Delphinium Consolida), Levant wormseed (Artemisia 
Paucifiora), lobelia (Lobelia inflata), nux vomica (Strychnos Nux- 
vomica), parsley seed (Apium Petroselinum), passion flower 
(Passiflora incarnata), poppy heads (Papaver somniferum), scullcap 
(Scutellaria lateriflora), senna (Cassia acutifolia and C. angustifolia), 
Serpentaria (Aristolochia Serpentaria and A.'reticulata), staphisagria 
(Delphinium Staphisagria), stramonium (Datura Stramonium).
