Source-derived summary

Hyalosperma praecox commonly known as fine-leaf sunray, is a flowering plant in the family Asteraceae. It is an upright, annual herb with stems branching from the base and yellow or white flowers and grows in New South Wales and Victoria.

Description

Hyalosperma praecox is an upright, multi-stemmed annual 10–20 cm (3.9–7.9 in) high with stems arising from the base. The leaves are narrow, green, 5–40 mm (0.20–1.57 in) long, decreasing in size toward the apex, upper leaves with a dry appendage, and tapering to a point. The white or yellow flowers are borne singly, bracts in several rows, outer bracts about 5 mm (0.20 in) long, inner bracts about 7–10 mm (0.28–0.39 in) long, corolla has five lobes and about 2 mm (0.079 in) long. Flowering occurs in spring and the fruit is an oval-shaped cypsela about 1 mm (0.039 in) long and may be either smooth or warty.

Taxonomy and naming

This species was first described by Ferdinand von Mueller and given the name Helipterum praecox. In 1989 Paul Graham Wilson changed the name to Hyalosperma praecox and the description was published in Nuytsia. The specific epithet (praecox) means "early".

Distribution and habitat

Fine-leaf sunray grows in open forests or grasslands on sand or heavy loam soils in New South Wales and Victoria.

Editorial summary

This brief starts where responsible research should: with the source description of “Hyalosperma praecox” as species of plant. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1989—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Hyalosperma, praecox and species can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Nov 19, 2023. The linked authority identifier is Q15585428. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1989.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
