One final thrill: On a good night, my little backyard three-inch telescope can make out the Trifid
Nebula quite nicely.
The two cotyledons have entire margins, the two pairs of eophylls ("primarblatter") have dentate margins, and above them, there is an abrupt change to trifid
spiny leaves on the main axis.
Key words: Hydronephrosis; trifid
pelvis; ureteropelvic junction obstruction.
Smoldering several thousand light-years away in the constellation of Sagittarius (the Archer), the Trifid
Nebula presents a compelling portrait of the early stages of a star's life, from gestation to first light.
Shape of paraprocts (males): entire (0), bifid (1), trifid
pinnata by its trifid
fertile fronds and differences in spore ornamentation.
Its characteristics are much as first described by Symonds in 1923--low-relief carving on the aprons of tables and seat furniture, usually on a diapered ground; decoration of rosettes, festoons, eagles' heads and tassels centred on lions' or other masks; baskets of flowers; acanthus leaves, shells, masks and cabochons on the knees of tables and chairs; flat, wavy stretchers on chairs; muscled or fetlocked legs; squared paw feet; webbed claw feet; panelled and trifid
feet; extended 'c' scrolls on the inside of legs.
Legs: femur I and 11 without basal swelling; femora I and 11 with primary slit sensillum directed transversely; femur I much longer than patella I; suture line between femur IV and patella IV transverse; metatarsus shorter than tarsus; metatarsal pseudotactile seta sub-proximal; legs with two bifid or trifid
subterminal tarsal setae; arolium longer than claws, not divided but slightly indented at fringed ventral margin; claws slender and simple.

The lower incisors of LSUMZ 21484 are unworn and are clearly trifid
with smaller, but distinct, middle cusps wedged between lateral lobes.
