Family - Euphorbiaceae
Stems - To 5m tall, glabrous, glaucous, suffrutescent (with age) or entirely herbaceous, branching, reddish, greenish, or purplish.
Leaves - Alternate, peltate, long petiolate, palmately 5 to 7 lobed, toothed, glabrous, to +30cm broad.
Inflorescence - Axillary racemes or loose panicles to +50cm tall, on thick peduncle.
Staminate Flowers - At base or lower portion of inflorescence, apetalous, pedicillate. Calyx typically 5-parted, reflexed. Stamens many, the filaments branching. Anthers yellow.
Pistillate Flowers - Capsules red, green or purple, covered with dense spines, +1.5cm in diameter, 3-seeded. Seeds mottled with copper, black, and bronze colors. Styles 3, red.
Flowering - August - November.
Habitat - Mostly cultivated. Also escaped to roadsides, railroads, waste ground, disturbed sites.
Origin - Native to Asia.
Other info. - This plant is the source of castor beans (used in ornamentation) and castor oil(pressed from the seeds). The plant is also more toxic than any other plant to humans. The seed cake which is left over after pressing contains a protein toxin known as Ricin which replaces a vital enzyme in cellular metabolism causing the shutdown of protein synthesis in the body. No protein - no life. The toxin contains an alpha section, which causes the cell shutdown, and a beta section which carries the molecule across the cell membrane.
Ricin has been used for assassinations, and has been experimented with for biological warfare. The LD 50 of Ricin is around 1/1000000 of the animals weight. It is VERY toxic. Pests which feed on the plant are usually killed.
The entire plant is toxic, but the seeds more than any other part.
The plant is, however, very striking in cultivation and many horticultural varieties exist. The typical species is mostly a green plant but I have found that the red form is very common in Missouri so I placed the plant in the red flowers section of this site.
The name Ricinus communis means "common tick" because the seeds resemble ticks.

Family - Fabaceae
Stems - Twining, thin, herbaceous, glabrous to appressed pubescent, terete, from rhizomes. Rhizomes often thickened into large tubers to +/-5cm in diameter.
Leaves - Alternate, odd pinnate with 3-7 leaflets, stipulate. Stipules linear, 5-6mm long, pubescent. Petiole thickened at base for 6-7mm, glabrous to sparse appressed pubescent, to +/-6cm long, with adaxial groove. Leaflets on short petiolules to 4mm long. Lateral leaflets ovate to ovate-lanceolate, entire, with some cilia on margins, glabrous above, glabrous to sparse pubescent below, acute to acuminate, to +6cm long, +2.5cm broad. Terminal leaflet more broad than lateral leaflets, on petiolule to 1.5cm long.
Inflorescence - Axillary pedunculate racemes to +/-8cm long. Peduncles typically glabrous, to 5cm long. Pedicels to 4mm in flower, subtended by small pubescent bract, with prominent gland in axil with stem.
Flowers - Corolla papilionaceous. Standard reflexed, deep purplish-maroon internally, lighter externally, whitish at base, 1cm long, 1.1cm broad. Wings deep brownish-purple. Keel lighter than other petals, greatly incurved, apex of keel tucked against the standard. Stamens 10, diadelphous. Stamen tube(connected filaments) white, glabrous. Anthers yellowish, .2mm long. Ovary pale green, 5-6mm long, pubescent. Style coiled as keel petals, white with green at apex, pubescent. Calyx glabrous, tubular, bilabiate. Upper lip with 3 lobes. Central lobe acute, 1.8mm long, with sparse pubescence externally. Lateral two lobes smaller, .6mm long. Lower lip with two shallow lobes. All lobes with minutely lacerate margins. Calyx tube 3mm long, green with some reddish tinge, glabrous internally. Fruit to +/-6cm long, -1cm broad.
Flowering - June - September.
Habitat - Wet meadows, streambanks, pond margins, moist woodlands.
Origin - Native to U.S.
Other info. - The plants thickened rhizome portions were a big hit amongst the Indians and used by settlers in this area. The rhizomes contain up to 3 times the protein of potatoes and can be boiled, fried, or roasted. The seeds are edible also. The plant is a fast growing perennial and, as stated above, prefers moist areas. I ate some of the rhizomes from this very plant while camping. I must admit, they could have used a little salt.

九里香的养护
土壤
九里香的培养土可用沙土、细炉渣、饼肥渣、塘泥、泥炭、河沙等六种原料以7：1：2：4：1的份数比例混合。盆地施含有磷钾肥的有机肥，增强迟效性，土壤砂质一定要有良好的排水性。
施肥
每两到三年追施一次有机的肥料，更换一次盆。5月是九里香的生长期，施肥加至每周一次，浓度也相应增加。
浇水
生长期每月给水一次，不宜过多。花期给水不仅要及时，而且要适量，这样才能保证花开的时候会更多、味道会更香。
光照
九里香是喜阳植物，全日照为好，光线稍差也不会影响太大。
温度
九里香抗寒行较好，喜温又喜热。18-28℃最佳，冬季温度5℃以下会影响生长。
九里香养殖的注意事项
初栽时需要盆地放置一些基肥。管理三怕,怕湿、怕冷、怕曝晒。多用有机肥、少用慎用化肥。

Family - Rosaceae
Stems - Woody, with dense straight prickles, hirsute, erect to clambering, to +1m tall. Prickles pubescent (at least at base).
Leaves - Alternate, odd-pinnate, with 5-7 leaflets. Stipules to 3cm long, 1cm broad, ciliate and glandular margined, glandular and pubescent below, glabrous above. Leaf rachis with prickles below, densely pubescent. Leaflets elliptic to rotund, crenate-serrate, glandular and pubescent below, glabrous and shiny above, rugose, 5-6cm long, 3-4cm broad.
Inflorescence - Single flowers from upper leaf axils. Peduncles to 1.7cm long, 3mm in diameter, densely glandular pubescent and non-glandular pubescent.
Flowers - Petals 5, rose, 4.5cm broad, 4cm long, free, glabrous, emarginate to obcordate, scented. Stamens very many (+100). Filaments white, glabrous, 6-7mm long. Anthers yellow, 2.1mm long, 1.2mm broad. Sepals 5, alternating with petals, lanceolate, joined at base, densely glandular pubescent below, pubescent above and on margins. Hypanthium subglobose, somewhat flattened, glaucous to moderately covered with prickles. Seeds many, crinite, with a hornlike protrusion.
Flowering - May - September.
Habitat - Cultivated and rarely escaped.
Origin - Native to Asia.
Other info. - I first read about R. rugosa in "This Old House Magazine", Sept./Oct. 1996. It's a great article and talks about the history and uses of the plant. Apparently the plant is quite popular on the island of Nantucket.
Personally, I'm not a huge rose fan, but this plant is nice. Nice to look at perhaps, but don't touch it. The stems are dense with stiff prickles. They may not be hooked prickles, but they can do damage none the less.
