The document provides information on several tree species: 1) The black mangrove grows in tropical and subtropical coastlines and can reach 10-15 meters tall. Its seeds germinate in midsummer. 2) The gumbo-limbo tree is native to tropical Americas and can grow up to 30 meters tall with reddish bark and pinnate leaves. It bears fruit year-round but mainly in spring. 3) The royal poinciana is cultivated as an ornamental tree for its large red or orange flowers and long seed pods. It provides shade as a modest sized tree.

1. Avicennia germinans
The black mangrove (Avicennia
germinans), is a species of flowering
plant in the acanthus
family, Acanthaceae.[2] It grows
in tropicaland subtropical regions of
the Americas, on both
the Atlantic and Pacific coasts, and on
the Atlantic coast of tropical Africa,
where it thrives on the sandy and
muddy shores that seawater reaches. It
can reach 10–15 m (33–49 ft) in height,
although it is a small shrub in cooler
regions of its range.
The seeds germinate in midsummer, but
may be seen all year on the trees.

2. Bursera simaruba
• Bursera simaruba, commonly known as gumbo-
limbo, copperwood, chaca, and turpentine tree, is a
tree species in the family Burseraceae, native to
tropical regions of the Americas from the southeastern
most United States (southern Florida) south
through Mexico and the Caribbean to Brazil
and Venezuela.Bursera simaruba is a small to medium-
sized tree growing to 30 meters tall, with a diameter of
one meter or less at 1.5 meters above ground. The
bark is shiny dark red, the leaves are spirally arranged
and pinnate with 7-11 leaflets, each leaflet broad
ovate, 4–10 cm long and 2–5 cm broad.

3. • The tree yields some ripe
fruit year-round, but the
main fruiting season is
March and April in the
northern part of the
plant's range. The fruit is
a small three-
valved capsule encasing a
single seed which is
covered in a red
fatty aril (seedcoat) of 5–
6 mm diameter

4. Delonix regia
• Delonix regia is a species of
flowering plant in the
family Fabaceae,
subfamily Caesalpinioideae. It
is noted for its fern-like leaves
and flamboyant display of
flowers. In many tropical parts
of the world it is grown as
an ornamental tree and in
English it is given the
nameRoyal
Poinciana or Flamboyant. It is
also one of several trees
known as Flame tree.
• In India it is known
as Gulmohar in Hindi.

5. • In the wild it is endangered, but it is widely
cultivated elsewhere. In addition to its
ornamental value, it is also a useful shade tree in
tropical conditions, because it usually grows to a
modest height (mostly 5 meters, but it can reach
an maximum height of 12 meters) but spreads
widely, and its dense foliage provides full shade.
In areas with a marked dry season, it sheds its
leaves during the drought, but in other areas it is
virtually evergreen. Flowers appear in corymbs
along and at the ends of branches. Pods are
green and flaccid when young and turn dark-
brown and woody.[4]

6. • The flowers are large, with four spreading scarlet
or orange-red petals up to 8 cm long, and a fifth
upright petal called the standard, which is slightly
larger and spotted with yellow and white. The
naturally occurring
variety flavida (Bengali: Radhachura) has yellow
flowers.[3] Seed pods are dark brown and can be
up to 60 cm long and 5 cm wide; the individual
seeds, however, are small, weighing around 0.4 g
on average. The compound leaves have a feathery
appearance and are a characteristic light, bright
green. They are doubly pinnate: Each leaf is 30–
50 cm long and has 20 to 40 pairs of primary
leaflets or pinnae on it, and each of these is
further divided into 10-20 pairs of secondary
leaflets or pinnules.

7. Carpentaria
• Carpentaria acuminata (Carpentaria
Palm), the sole species in the
genus Carpentaria, is a palm native to
tropical coastal regions in the north
of Northern Territory, Australia.
• It is a slender palm, growing to 20 m tall in
the garden situation, with a trunk 12-
15 cm diameter. The leaves are pinnate, 3-
4 m long. However, in its natural rainforest
location such as at Fogg Dam Monsoon
Forest 70 km east of Darwin, specimens
often exceed 30 metres in height. It is a
popular ornamental plant in northern
Australia, valued for its rapid growth and
very elegant foliage.

8. • . From the time of the Greek Cross Design it is clear that Wren favoured a
continuous coloaround
• the drum of the dome, rather than the arrangement of alternating windows and
projecting columns that Michelangelo had use
• Above the peristyle rises the second stage surrounded by a balustraded balcony
called the "Stone Gallery". d nnade
This attic stage is ornamented with alternating pilasters and
rectangular windows which are set just below the cornice,
creating a sense of lightness
The total weight of the lantern is about 850 tons.[70]

10. The remarkable feature here is that the lower storey of this portico
extends to the full width of the aisles, while the upper section defines
the nave that lies behind it. The gaps between the upper stage of the
portico and the towers on either side are bridged by a narrow section
of wall with an arch-topped window
The transepts each have a semi-circular entrance portico
WALLS…..The building is of two storeys of ashlar masonry, above
a basement, and surrounded by a balustrade above the upper
cornice
. The height from ground level to the top of
the parapet is approximately 110 feet

11. The choir, looking towards the nave
Interior[edit]
Internally, St Paul's has a nave and choir each of three bays. The entrance from the
west portico is through a square domed narthex, flanked on either side by chapels: the
Chapel of St Dunstan to the
The cathedral is some 574 feet (175 m) in length (including the portico of the Great West
Door), of which 223 feet (68 m) is the nave and 167 feet (51 m) is the choir. The width of
the nave is 121 feet (37 m) and across the transepts is 246 feet (75 m).[76] The cathedral
is thus slightly shorter but somewhat wider than Old St Paul's.

12. Dome[edit]
The interior of the dome showing how Thornhill's painting continues an illusion of the real architectural features.
This view of an arch spanning the aisle shows how Wren succeeded in giving an impression of eight equal arches.
The dome is supported on pendentives rising
between eight arches spanning the nave, choir,
transepts, and aisles. The eight piers that carry
them are not evenly spaced.

13. Above the keystones of the arches, at 99 feet
(30 m) above the floor and 112 feet (34 m)
wide, runs a cornice which supports
the Whispering Gallery
. It is reached by 259 steps from ground level.
. the dome rises above a gilded cornice at 173 feet (53 m) to a
height of 214 feet (65 m)
Artworks, tombs and memorials[edit]

St Paul's at the time of its completion, was adorned by sculpture in stone and wood, most notably that of Grinling Gibbons, by the paintings in the dome
