ACTIVITY 1 - Leaf Morphological Characterization 
Name:. SOREN R. CHOA. DATE : APRIL 19, 2021 
 
Course:. BS BIOLOGY Year Level & Section:. 1ST YEAR / C 
Instructions: 
1. Select at ten (10) plants found adjacent to your residence and collect the leaves using a pair of scissor. If the 
plant is within the residence of your family relative/neighbor ask for permission to collect. 
2. Take a photo of the plant bearing the date and GPS reading. 
3. Collect the stem with leaves for trees, one leaf is enough for herbaceous plant. 
4. Make a morphological characterization of the collected plant sample.

MORPHOLOGICAL CHARACTERIZATION: 
 
NAME OF THE SAMPLE 
PLANTS 
 
 
MORPHOLOGICAL CHARACTERIZATION 
1.DUMB CANE 
( Dieffenbachia ) 
 
Dumb cane, (genus Dieffenbachia), any of about 30 species of 
herbaceous plants valued as indoor foliage for their ability to tolerate 
low light intensities. The name mother-in-law’s tongue, sometimes 
used for these plants, is also applied to Sansevieria species. Dumb 
cane (especially D. seguine) gets its name from the temporary 
speechlessness that occurs after chewing a piece of the stem. Juices 
of the plant contain oxalates and other substances that irritate the 
mucous membranes and cause swelling and inflammation of the 
tongue and throat. Dumb cane is reported to have been given to 
slaves as a form of punishment. 
 
 
 
 
Dieffenbachia includes about 30 species of erect tropical American 
herbs in the arum or aroid family (Araceae). Only a few display fancy, 
large, more or less variegated leaves; they include D. maculata 
(formerly D. picta) and D. seguine (native to the West Indies), both of 
which have yielded colourful varieties of horticultural interest. D. 
amoena is a plant of large size, up to 6 feet (180 cm) or more, with 
20-inch- (50-cm-) long leaves, having creamy markings along the 
larger veins. Flowers are borne on a long spadix, with male flowers on 
top and female flowers below. A row of sterile flowers separates the 
two sexes. Clusters of bright red or red-orange berries are the 
resultant fruits. The genus was named for an Austrian gardener of the 
1800s who worked at Schönbrunn. 
 
 
 
 
 
2. BIRDNEST 
( Asplenium nidus) 
It is characterized by dramatic foliage similar in appearance to banana 
leaves. Large, simple, stemless, strap-shaped, bright green fronds 
have a dark brown-black mid-rib and wavy margins. Overlapping 
fronds form a rosette with a nest-like center, spreading upwards then 
gracefully arching outwards. 
3. CALATHEA 
( Calathea lutea) 
The genus Calathea is comprised of some of the most attractive 
species of foliage plants. Calathea insignis, also called Rattlesnake 
plant, is a bushy species with narrow, tapering erect foliage, wavy at 
the margins, yellow green with lateral ovals, alternately large and 
small, of dark green. The underside is maroon. 
4. FRYDEK ALOCASIA 
( Alocasia Micholitziana ) 
Frydek’ is a hybrid selection of elephant’s ear that features dark, 
velvety-green, heart-shaped leaves with contrasting white veins. Will 
occasionally flower and produce a typical aroid-type inflorescence 
with a light green spathe surrounding a creamy white, spike-like 
spadix. 
5. MAYANA 
( Coleus blancoi) 
Mayana is an erect, branched, fleshy, annual herb, about 1 meter 
high. Stems are purplish and 4-angled. Leaves are variously blotched 
or colored, usually more or less hairy, ovate, 5 to 10 centimeters long, 
rather coarsely toothed in the margins; and in the most common 
form uniformly velvety-purple. 
 
 
6. BOSTON FERN 
(Nephrolepis exaltata) 
Fern consists of feathery leaves. The plant body is differentiated into 
roots, stem and leaves. The roots and stem are underground and only 
the leaves are aerial. Fern plant is classified under Pteridophyta 
division because they contain feathery leaves. 
7.BEGONIA 
(semperflorens-cultorum) 
They are from the tropics and subtropics. Prominent features are 
their usually four-coloured tepals (petals and sepals together) in two 
pairs of different sizes and the three wings on the ovaries of the 
female flowers. Flower colours are pink, red, yellow, or white, with 
the ovary below of the same colour. 
8.ALOCASIA CUCULLATA 
 
The Alocasia cucullata has beautiful heart shaped glossy green foliage 
with prominent veins on tall green stems. Also known as Buddha’s 
hand it is believed to bring good fortune and is often kept in Buddhist 
temples across its native Thailand and Laos. Combine with the Swiss 
cheese plant, Monstera deliciosa for tropical tranquility in your home. 
cucullata is a species of flowering plant in the arum family known by 
the common names Chinese taro, Chinese ape, Buddha’s hand, and 
hooded dwarf elephant ear. It is kept as an ornamental plant. 
9.ANAHAW 
(Saribus rotundifolius) 
Anahaw is a round-leaf fountain palm, medium-sized to large, 
growing between 18-27 meters high, with a slender solitary trunk 
about 20-25 centimeters in diameter, bearing prominent leaf scars, 
and clothed with beautiful grayish woven fibers in the upper part 
below the crown. 
10. BANANA 
(Musa × paradisiaca) 
It is commonly thought that bananas grow on trees; however this is 
not exactly the case. Although a banana “tree” can grow up to 20 feet 
tall, a banana tree isn’t a tree at all; it’s the world’s largest herb. Thefruit itself is actually a giant berry, and what is often thought of as the 
trunk of the tree is just a large modified stem. 
 
Bananas are perennial plants, meaning they grow and produce 
flowers multiple times over a period of years. The life cycle of a 
banana plant are divided into two distinct phases: the vegetative 
phase (in which the plant prepares itself for reproduction) and the 
and reproductive phase (in which the plant begins to produce fruit).
