A Handbook of Some South Indian Grasses These bud-like bodies are the units of the inflorescence and they are called spikelets. A Handbook of Some South Indian Grasses Each of these spikelets consists of four green membranous structures called glumes. A Handbook of Some South Indian Grasses It is the first leaf occurring in every branch on the side next to the main shoot and it is a two-keeled membranous structure resembling somewhat the palea found in the spikelets of grasses. A Handbook of Some South Indian Grasses The outer are shorter than the inner, glabrous, erect or subsquarrose and as long as the sessile spikelets. A Handbook of Some South Indian Grasses But in grasses the unit of the inflorescence is the spikelet and not the flower. A Handbook of Some South Indian Grasses When the spikelets are sessile or borne directly along an elongated axis as in Enteropogon melicoides the inflorescence is a spike. A Handbook of Some South Indian Grasses If the spikelets borne by the axis are all stalked, however short the pedicels may be, it is a raceme. A Handbook of Some South Indian Grasses An inflorescence may appear to be a spike, but on a close examination it will be seen to consist of spikelets more or less pedicelled. A Handbook of Some South Indian Grasses The spikelets are about 1/6 inch long, sub-globose, with four glumes. A Handbook of Some South Indian Grasses The inflorescence is a panicle when the spikelets are borne on secondary, tertiary or further subdivided branches. A Handbook of Some South Indian Grasses What looks like a spike in these cases consists of a jointed axis and each joint bears a pair of spikelets, one sessile and the other pedicelled. A Handbook of Some South Indian Grasses As a type for the spikelet that of an Eragrostis or Dinebra may be chosen. A Handbook of Some South Indian Grasses In this spikelet the rachilla bears a number of glumes alternating and imbricating. A Handbook of Some South Indian Grasses The spikelets are usually one to two and rarely three in an involucel and each one has four glumes. A Handbook of Some South Indian Grasses The first two glumes at the base of the spikelet do not bear any flowers and so these two glumes are usually called empty glumes. A Handbook of Some South Indian Grasses The spikelets vary very much in their structure. A Handbook of Some South Indian Grasses The spikelets in grasses of several genera consist of only four glumes. A Handbook of Some South Indian Grasses The glumes of a spikelet are really modified bracts and some differentiate the flowering glumes from the empty ones, by giving them different names. A Handbook of Some South Indian Grasses The spikelets are in panicles, 1-flowered and the flower is usually perfect. A Handbook of Some South Indian Grasses In the spikelet having only four glumes the fourth glume differs from the others mainly in texture. A Handbook of Some South Indian Grasses The palea can easily be distinguished from the glume, because its insertion in the spikelet is different from that of the glume. A Handbook of Some South Indian Grasses This may be seen in the spikelets of the species of Cynodon. A Handbook of Some South Indian Grasses Each spikelet contains a single perfect flower and sometimes in addition a staminate flower just below the perfect flower. A Handbook of Some South Indian Grasses The spikelets are jointed on their pedicels and fall away from them. A Handbook of Some South Indian Grasses But the rachilla of the spikelet may be jointed just above the empty glumes or between the flowering glumes. A Handbook of Some South Indian Grasses When mature the spikelets fall away either by themselves, singly with their pedicels or in groups with portions of rachis, according to the position of the joint. A Handbook of Some South Indian Grasses The styles are slender and distinct with plumose stigmas exserted at the top of the spikelet. A Handbook of Some South Indian Grasses The spikelets are small, 1/20 to 1/14 inch, geminate, one short and the other long pedicelled, appressed to the rachis, elliptic, silky with slender crisped hairs, pale green or purplish. A Handbook of Some South Indian Grasses There is usually a complete flower in a spikelet and the glumes are membranous. A Handbook of Some South Indian Grasses In this grass very often, purple streaks or bands occur across the leaf blades and the sheath and the spikelets become purple on one side as is met with in P. colonum. A Handbook of Some South Indian Grasses This plant occurs widely as a weed of cultivation in black cotton as well as other kinds of soil and shows variation in its leaves and spikelets. A Handbook of Some South Indian Grasses The spikelets are either perfectly glabrous or pubescent and long hairs may or may not be present on the pedicels. A Handbook of Some South Indian Grasses As regards colour the whole plant is green or the exposed portions of stems and spikelets are purplish. A Handbook of Some South Indian Grasses Mature spikelets are deciduous with their pedicels singly in Perotis and in clusters in others. A Handbook of Some South Indian Grasses The spikelets are glabrous, green, herbaceous, densely packed in small fascicles, ovoid lanceolate, 1/6 to 1/5 inch long; many spikelets are imperfect. A Handbook of Some South Indian Grasses The spikelets are glabrous, erect, pale or pale green, sometimes purplish also on one side, ovate-oblong or oblong-lanceolate, acute, 1/8 inch, pedicels are long with cupular tips. A Handbook of Some South Indian Grasses Each spikelet is solitary, and articulate at the very base of a rachis, lanceolate, 1-flowered. A Handbook of Some South Indian Grasses The first three glumes are as in the male spikelets, but larger. A Handbook of Some South Indian Grasses The spikelets are compressed and consist of only one glume bearing a perfect flower. A Handbook of Some South Indian Grasses The female inflorescence is a large globose head consisting of short spikelets articulate at the very base of the rachis, short bracts and very long, spreading, rigid rod-like rachises. A Handbook of Some South Indian Grasses The spikelets are numerous and are very closely set along the rachis of the inflorescence, 1/8 inch long, glabrous and ellipsoidal. A Handbook of Some South Indian Grasses The spikelets are ellipsoidal, obtuse, glabrous, 1/12 inch long. A Handbook of Some South Indian Grasses The second glume is as long as the spikelet or a little shorter, ovate, subacute, thinly membranous and 5-nerved.

A Handbook of Some South Indian Grasses The involucels are shortly stalked, with a few unequal bristles which are free down to the base and two to three times as long as the spikelet. A Handbook of Some South Indian Grasses The spikelets are arranged in groups of two, facing each other and appearing like a single spikelet with two equal echinate glumes, sessile, or obscurely pedicelled on very short, tumid, pubescent branches. A Handbook of Some South Indian Grasses The spikelets are usually arranged in pairs at each joint, one sessile and the other stalked. A Handbook of Some South Indian Grasses In the genera Polytoca and Coix the spikelets are unisexual and the male and female spikelets are found in the same inflorescence, the female being below and the male being continuous with it.

A Handbook of Some South Indian Grasses The lowest-spikelet in the raceme is female and this is enclosed in a bract which at length becomes hardened, polished and nut-like and the other spikelets above it are male. A Handbook of Some South Indian Grasses The female spikelet is enclosed by a closed bract which finally becomes hardened, and there are four glumes in the spikelet. A Handbook of Some South Indian Grasses The racemes of the latter are longer and drooping, the male spikelets are in threes and the wings of the first glume are usually broader than in the other form.

A Handbook of Some South Indian Grasses I. ciliare.Raceme solitary; the first glume of the sessile spikelet deeply grooved at the back along the middle line. A Handbook of Some South Indian Grasses The spikelets are large about 1/4 inch long cuneate and bifarious. A Handbook of Some South Indian Grasses There are five or seven glumes in a spikelet. A Handbook of Some South Indian Grasses This species is a tall robust one resembling Chloris barbata in its inflorescence, but with larger spikelets—as large as those of Chloris tenella. A Handbook of Some South Indian Grasses The spikelets are sessile, 3 to 12 flowered, 2 to 3-seriate, secund, laterally compressed and forming digitate whorled or capitate spikes, not joined at the base; rachilla continuous between the flowering glumes.
