I have had these two plants for awhile now and have been unable to identify either. I usually have no problems with identification with the books I have on hand, but these two have defied those resources. The Monocot I acquired with the name of Zanzibar Leopard Lily and that has led nowhere. Coll. # 1266.1, Acc. # 3060, 6-19-1999; Bloom time late April to June, fruit ripens in 2 months; Inflor. is scape about 15 cm long, small white flowers about 0.5 cm, peduncle very short; fruit about 0.8 cm, ripens yellow; seed black or dark purple, ovoid, shinny, smooth, 0.6 cm fresh, dries to 0.45 cm, stippled and shinny; axis of fruit appears to be variable to rachis, germination in about 23 days; pseudo bulb 4 cm dia; 5 cm tall from soil; leaves, blade 8 cm x 4 cm, deltoid, spotted, shinny, acute apex, truncate base; petiole 7 cm, channeled, reddish in same shade as spots on blade. Freely offsets. The Cactus I can ID to Echinocactaneae and that is as far as I can go in any of my books. It is not in Britton and Rose but the characteristics take it to this tribe. Plant collection # 1646.1, Accession # 4207, 11-14-2003 with 3 seed collections covering about 7 years of flowerings up to 2006. body columnar 17 x 6.5 cm, med. Yellow-green; ribs 20 straight, 0.4 cm deep; areoles round, 0.25 to 0.3 cm dia., 0 .2 cm apart, short white wool, 9 whorls right, 11 left; spines, radial ca. 15, thin, white, up to 0.5 cm, straight; central 9, 1 center, 8 surround, stouter, to 1.2 cm. straight, rusty brown to yellow in rings on spine and bands on plant; flowers, petals bright lemon yellow, 1 to 2 cm long, narrow, spread to 4 cm, at shoulder of plant, bloom time about 1.5 months, and doing so in 3 or so ranks; visual: bud, just at color break, looks much like our local (Oklahoma) Tarantula’s (wolf spider) abdomen in shape, color and hairs; stigma, bright magenta red, 12-13 lobes, exerted above yellow numerous stamens; ovary 1 x 0.6 cm, brown scales with white to golden brown hairs and bristles to 0.7 cm, ruptures at bottom pore; seeds black, dull, spheroid, mucro evident, about 0.1 cm dia., germination time aprox. 1 mo.
Perhaps Drimiopsis maculata on the first one. The common name Leopard Plant is often used for Ledebouria, but your details didn't seem to fit that one. If you Google (use the image search) it, you'll find many pix to compare to it.
Those lemon-yellow flowers on the cactus immediately make me think of Parodia (in the broad sense, including Notocactus). But I would not like to say which species. I agree with Rosemarie about Drimiopsis maculata. I have it growing myself.
I had the same thoughts as Tony on your cactus, looking up Notocactus/Parodia ottonis & scopa (& others), but couldn't find a match for the body/spines...so I didn't say. :) Someone on the thegardenforums.org might be able to pin it down for you though. On the other one...Glad to help!
I see what you mean about the flower looking very much like but not the body. Still at a dead end on the cactus.
I know this reply is somewhat late pertaining to your post, but I happened to be searching for more info on this particular bulb and found your post. I have a plant I purchased called "Zanzibar Leopard Lily" - Drimiopsis Kirkii.
Definitely a Parodia formerly called a Notocactus. Drimiopsis maculata has petiolate leaves that are deciduous in winter. The allied Drimiopsis kirkii differs by having fleshy evergreen strap-shaped leaves.
