FAMILY OF THE WEEK : GENTIANACEAE

About 80 genera and 700 species worldwide.

Vegetative Characters : Herbs [shrubs or small trees], annual, biennial, or perennial. Stems ascending, erect, or twining. Leaves opposite, less often alternate or whorled, simple, base connate; stipules absent. Inflorescences simple or complex cymes, sometimes reduced to sessile clusters, often in a thyrse or 1-flowered. Flowers bisexual, rarely unisexual, 4 or 5 (or 6-8)[-12]-merous. Calyx tubular, obconic, campanulate, or rotate, lobes joined at least basally. Corolla tubular, obconic, salverform, funnelform, campanulate, or rotate, rarely with basal spurs; lobes overlapping to right or rarely valvate in bud; plicae (extensions of the corolla tube between the lobes) present or absent. Stamens inserted on corolla tube or occasionally at sinus between corolla lobes, alternate with lobes; anthers basifixed or dorsifixed, 2-locular. Nectaries absent or attached to ovary base or corolla. Ovary usually 1-locular at least apically, rarely 2-locular due to intrusion of a lamellate placenta into locular cavity. Fruit a 2-valved capsule, rarely a berry. Seeds many or rarely few, small; endosperm abundant [scant in saprophytic genera].

Pollination by insects.

Examples:

Exacum

Enicostema

Centaurium

Hoppea

Canscora

Swertia

I could gather very little information about this family.Most of the examples of this family are found in Himalayan region. Some are also found in Western ghats.The photograph attached in the above mail is most probably from Genus Swertia. I have observed some flowers of Exacum at Kas near Satara but don't have good photographs.I request the members to send their pictures as well as information of the plants of this beautiful family.

Regarding the species ID of Swertia...I don't have total field characters of the plant. The picture has been searched from my collection.Even I don't remember where I have shot it..either Kas lake plateau or Mahabaleshwar.
Acc. to Shrikant's book it appears to be Swertia densifolia.
