I collect a lot of seeds each year from plants which I find especially interesting for one reason or another. Much of my research includes plants from somewhat inaccessible populations, especially for obscure and uneconomically-important species. I gather these seeds for my own and collaborators’ projects, as well as to have on hand for folks interested in projects using them. As many folks have kindly sent me seeds for projects, I hope to pay it forward in a way.
I'd be happy to send along most seeds I have for investigations. I did not include seeds available through the USDA GRIN program, which is an invaluable program to me and other plant researchers. A partial list is here (way out of date...), I'm also happy to collect seeds of other species if convenient.
Focal groups and species below. Feel free to email me for more information: eric.lopresti@okstate.edu
1) the Chenopodiaceae
2) Abronia/Tripterocalyx
3) Trichostema laxum, as well as some other Trichostema
4) Plants with mucilaginous seeds (largely mints, but also some scrophs, acanths, plantains, etc.)
5) sticky "Mimulus" (Diplacus/Erythranthe) species.
6) Assorted sticky plants (Proboscidea, columbines, tarweeds, gilias, petunias, tobaccos, etc.).
7) I am building up a collection of plants with sticky but non-mucilaginous seeds, but it is small so far (Boerhavia, Momordica, etc.)
A (very, very) incomplete list:
By family, families in no particular order.
Nyctaginaceae
Abronia latifolia (seeds/cuttings)
Abronia umbellata (both ssp., seeds/cuttings)
Abronia maritima (cuttings, seeds too, but easy from cuttings)
Abronia turbinata (seeds, several pops.)
Abronia villosa (seeds/cuttings - lots of pops, both ssp.)
Abronia fragrans (seeds/cuttings, several pops)
Abronia pogonantha (seeds)
Abronia elliptica (seeds/cuttings)
Abronia angustifolia (seeds)
Abronia bigelovii (may have cuttings soon)
Tripterocalyx crux-maltae (seeds)
Tripterocalyx micrantha (seeds)
Tripterocalyx carneus (seeds)
Boerhavia diffusa (Chilean population - seeds/plants)
Boerhavia coccinea, Miami
Allionia incarnata
Lots of Abronia hybrids I made in the lab (study these... please! Many occur naturally, there is at least one zone of character displacement, all sorts of cool dynamics. )
Chenopodiaceae
Chenopodium
C. album (15+ populations, Maine to California)
C. sp. nitens?, White Mountains, CA. Cool tiny prostrate thing.
C. nevadense, CA. smelly.
C. vulvaria, a very, very, weird plant, produces copious amounts of trimethylamine (the compound giving rotten fish its unique aroma), is introduced worldwide. I have some scattered data on herbivory (+ some ideas of functional significance). I have pops from Portugal, Chile, and CA.
Also other spp. which I grew out from USDA GRIN stock (preferable to order from them, but I have amplified some).
Atriplex
A. argentea
A. canescens (few populations)
A. hortensis (heterocarpy AND heterospermy)
A. lentiformis
A. rosea
A. vesicaria
(contact me for more Atriplex seeds, as they are no longer in GRIN, but I have other accessions)
Others
Blitum californicum, CA
Oxybasis glauca, CA (two pops)
Dysphania ambroisoides, CA
Dysphania sp. (botrys?), CA/MA
Suckleya suckleyana, (seriously cool plant; from USDA CO stock. Weird trichomes on leaf margins)
Lamiaceae
Trichostema laxum, CA (germination easy) I have thousands of seed packets with varying characteristics, across 30+ populations, from the range edge to near the center, though most are populations within a few miles of the Yolo/Lake/Napa Co. convergence. A very cool plant, looking for collaborators or for other people to study it independently. See its page on this website.
Trichostema lanceolatum, CA (germination difficult)
Trichostema simulatum, OR, (germination easy)
Lepechinia calycina, CA
Scutellaria spp. CA
Various Salvia, Ocimum, Thymus, etc., species which I am using to study mucilaginous seeds. Mostly ornamentals/herbs, .
Assorted families:
Proboscidea parviflora, AZ
Proboscidea louisianica, MI
Antirrhinum virga, CA (awesome huge showy snapdragon bush)
Antirrhinum cornutum, CA (somewhat glandular, germination easy!)
Verbascum blatteria, CA, Chile (rather glandular)
Mimulus [Diplacus] bolanderi, CA (fire following population)
Mimulus pilosus, CA (fire following population)
Argemone munita, CA (fire following population)
Emmenanthe penduliflora, CA (fire following population)
Mentzelia dispersa, CA (fire following population)
Mimulus [Diplacus] douglassii, CA (+ data on cleistogamy rates in a natural population)
Plantago erecta, CA (serpentine pop)
Plantago lanceolata, CA (mild serpentine)
A few sticky Phacelia spp. which I haven't grown/keyed. =
Navarettia mellita, CA (nice and sticky inflorescences)
Navarettia jepsonii, CA (showy serp endemic)
Navarettia pubescencs, CA
Navarettia sinistra, CA, (serpentine, sticky, weirdly Gilia-like)
Croton/Eremocarpus setiger/us - (mucilaginous, cool stellate trichomes)
Plantago erecta, CA (serpentine/nonserpentine pops)
Castilleja minor, CA (oily/slimy surface, cool overcompensation response in natural populations)
Dicentra/Ehrendorferia chrysantha, CA (fire-follower)
Clarkia unguiculata, CA
Solanaceae
Datura stramionum, MA/CA
Petunia axillaris
Petunia exserta
Petunia integrifolia
Petunia F1 hybrids of the above species
Nicotiana quadrivalvis, CA
Ranunculaceae
Aquilegia eximia, CA
Aquilegia shockleyi, CA (have not grown, very sticky!)
Asteraceae
Calycadenia sp. (multiglandulosa/pauciflora), CA
Hemizonia congesta, CA
Holocarpha virgata, CA
Madia elegans, CA (seeds from red, yellow and intermediate morphs as shown on left)
Many more...
