It is considered that flower plays an important role in angiosperm taxonomy. But what about the angiosperm which have irregular flowering behavior or flower at a large interval of time?
Question is not clear. What do you mean by irregular flowering behaviour? In case of plant species that flower at one time in lifespan or intermittently, one need to wait until flowering happens if that is the only defining criteria or criterion to identify the species.
Dear Sir,
Irregular flower refers to flowers over a period of time e.g. bamboo.
To identify the plant properly the knowing of flower and flower formula is essential as it is one of the component for proper identification of plant, each flowering plant is differ in the flower pattern.
It is unfortunate that so many botanical keys focus on floral characteristics in the first instance and this applies to grasses in particular. If you are working with bamboo there should be good vegetative characteristics to separate described species. If you are looking at variation within a single species then you may need to be incredibly patient and in the meantime access herbarium material. In horticulture flowering of fruit trees is sometimes induced before maturity by the application of plant hormones, gibberellins I think, or by stressing the plants.
Flower character is key character, It gives imp. keys for the identification such as polypetalous, gamopetalous. Flower color too considered a key for the identification. Irregularity in the structure of flower is evolution by time interval. It can meant for pollination, protection from unwanted entries.
From species to species morphologically many variations are there. If we are classifying or identifying plants based on vegetative organs its more complicated to give 100% of inferences but using sexual organs means flowers if there more possibility because the flowers has unique characters themselves compared to other species. This unique features are the key for classification of plants or varying plants to plants; tatsy Bentham and Hookers classification was accepted by many researchers and followed too.
Irregular flowering in Bamboo is incorrect. In this species, flowering occurs once in lifetime and then it dies. This type of flowering is referred to a form of mast flowering.
@The role of flower in identification is very important. The other vegetative parts of the plant may differ in appearance due to climatic conditions, geographical location, and various biotic and abiotic stresses. In these cases, the floral parts or the floral formula can play a very important role in the correct identification of the species.
But in cases, where flowering occurs after a long duration or once in the life cycle of the species, it is sometimes difficult to identify the species. In these cases, chromosomal analysis and biochemical studies can help.
Recent molecular approaches are also of great significance in the identification of species.

If you want to identify the view inside a certain genus, most often along with the specific features of the flower has a specific and vegetative characteristics. The latter are not always clearly visible, often microscopic characteristics. But also can also be genus specific vegetative characteristics, which allow to identify them without flowers. For some genera have special keys, but often have to look for these signs himself, based on a precise definition of the samples with flowers.
Identifying the plant species without flowers/ irregular flowering patterns is challenging one. Since we can not determine the sexual/breeding systems (in case of doiecy) of the plant, and may need to wait until flowering. But with the help of taxonomic key with other morphological characters we could determine the plant till genus level.
the flowering period of angiosperms are uncertain who have irregular flowering behavior or interest on a large time interval, the introduction of its kind can be done by looking at the habitus and morphological characteristics of leaves, where the position of the leaves on the stem also stem morphology.
First step in flowering plant identification in my flowering plant taxonomy labs is to systematically produce a floral formula for the unknown specimen. Like it or not, floral structure is (and will continue to be, "DNA Jocks") the basis of flowering plant taxonomy!
The shape, size and finer details of different parts of a flower helps one to identify a species. Moreover the flower color and structure helps one to get a clue on its pollinator and pollination biology.
Basic concept of the plant taxonomy works on the flower, which deals many more things to enter to the Plant systematics poly, gamo, unisexuales, monocious, diocious,. KEY TO GO FOR THE family IF WE GOT FAMILY EAISELY GO FOR THE SPS AND GENUS. WITHOUT FLOWER WE are not able to classify the plant.
Flower formula plays an important role in identification of characteristic features of a particular Angiosperm family plant; in some controversy the other parts taxonomy features are to be considered in classify the plant.
