Raceme
A raceme (/reɪˈsiːm/ or /rəˈsiːm/) is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers — flowers having short floral stalks called pedicels — along its axis. In botany, an axis means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers are borne towards the base and new flowers are produced as the shoot grows, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. Cimicifuga racemosa. A compound raceme, also called a panicle, has a branching main axis. Examples of racemes occur on mustard (genus Brassica) and radish (genus Raphanus) plants.
A spike is an unbranched, indeterminate inflorescence, similar to a raceme, but bearing sessile flowers (sessile flowers are attached directly, without stalks). Examples occur on Malabar nut (Justicia adhatoda) and chaff flowers (genus Achyranthes).
A spikelet can refer to a small spike, although it is primarily used to refer to the ultimate flower cluster unit in grasses (family Poaceae) and sedges (family Cyperaceae), in which case the stalk supporting the cluster becomes the pedicel. A true spikelet comprises one or more florets enclosed by two glumes (sterile bracts), with flowers and glumes arranged in two opposite rows along the spikelet. Examples occur on rice (species Oryza sativa) and wheat (genus Triticum), both grasses.

As a name
Spike (musician)
Jonathan Gray (born February 4, 1968), known professionally as Spike (sometimes also known as Spike Gray), is an English rock frontman, songwriter and vocalist, known for his times with The Quireboys with whom he has released seven studio albums to date.
Early life and education
Gray was born in Newcastle upon Tyne and grew up in Northern England.
Career
At age 17, he moved down to London where, eventually, he would form the rock band The Quireboys with Guy Bailey in 1984. After various tours and singles, Spike with The Quireboys released their debut album A Bit of What You Fancy (1990), which went to number two on the UK Albums Chart. The band gained significant success, but their second album Bitter Sweet & Twisted (1993) did not quite have the impact of the first.
After The Quireboys split up in 1993, he played in the United States, in Los Angeles, California, with a band called God's Hotel. He also sang lead vocals on a cover of Hank Williams's country classic "Hey Good Lookin'", with C.C. DeVille from the American glam-metal band Poison, for the soundtrack of the comedy film Son in Law (1993) that starred Pauly Shore.
