A stipule is "intrapetiolar" if it is located in the angle that is between a stem and a petiole. In this case, the two stipules generally form together and appear to be one stipule. A stipule is "ochreate" if a single stipule appears to be a solid tube that goes all the way around the stem. A stipule is "foliaceous" if it is leaf-like.
Artocarpus sericicarpus measures up to 30–40 m (100–130 ft), stipule are lanceolate and measure at 6–12 centimetres (2–5 in) and its dark green leaves are elliptic and ovate and measure at 20–70 cm (8–28 in) by 10–50 cm (4–20 in).
Psoralea fascicularis, the large-stipule fountainbush, is a species in the pea or Fabaceae family. [3] It is endemic to the Western Cape province of South Africa where it has been red listed as endangered (EN) by the International Union for Conservation of Nature (IUCN) Red List of Threatened Species (also known as the IUCN Red List or Red Data Book) due to its declining population.
In flowering plants, the term is often used in reference to a stalk that sometimes supports a flower's ovary. In orchids , the stipe or caudicle is the stalk-like support of the pollinia . It is a non-viscid band or strap connecting the pollinia with the viscidium (the viscid part of the rostellum or beak).

Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
The majority of species are shade-loving herbaceous plants or shrubs, which are easily distinguished from other Urticaceae by the combination of opposite leaves (with rare exceptions) with a single ligulate intrapetiolar stipule in each leaf axil and cymose or paniculate inflorescences (again with rare exceptions).
All the leaves are arranged alternately along the stem, with petioles up to about 8 cm long (or even 20 cm long in the case of some submerged leaves). At the base of each petiole is a small, ovate stipule. Plants characteristically have both laminar and capillary leaves. Flowering occurs between May and September in Northern Europe.
